ipv6calc is a small utility written in programming language C to manipulate (not only) IPv6 addresses and is able to do other tricky things. Intentions were convering a given IPv6 address into compressed format, convering a given IPv6 address into the same format like shown in /proc/net/if_inet6 and (because it was not difficulty) migrating the Perl program ip6_int into. Now only one utiltity is needed to do a lot.
This utility was also used in the past to extend features on network-functions-ipv6 library, used by initscripts-ipv6.
Note: this tool got also its freshmeat / ipv6calc page (not maintained by the author)
“ipv6calc”: the main utility
“ipv6calcweb”: CGI wrapper for ipv6calc's address information output
“ipv6logconv”: log converter (IPv4/IPv6)
“ipv6loganon”: log anonymizer (IPv4/IPv6)
“ipv6logstats”: log statistic generator (IPv4/IPv6)
If not disabled during compiling the tool, following databases are statically included, since version 0.95.0 internally mentioned as “BuiltIn”:
IEEE IAB, OUI, OUI-36 databases (for decoding vendor part of MAC/EUI-48/EUI-64)
Aggregated IPv4 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv4 anonymization)
Aggregated IPv6 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv6 anonymization)
Aggregated ASN assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for IP anonymization)
If enabled during compiling the tool, following external (but local stored) databases can be used
GeoIP IPv4, IPv6 (since 0.90.0, req. GeoIP >= 1.4.5)
IP2Location IPv4, IPv6
Since version 0.95.0 the tool can be compiled to use dynamically loading of library, means the binaries can be also used on systems where IP2Location or GeoIP libraries are not existing. On such system, the support is simply disabled then and some capabilities/features which requires the databases are disabled.

A SPEC file is included, so you can build a RPM from tar.gz using
$ rpmbuild -ta path/to/ipv6calc-$version.tar.gz |
In addition, conditional build options are available (see related configure options below):
--with geoip --with geoip-dyn --with ip2location --with ip2location-dyn --with shared |
Currently only on rpmfind / ipv6calc, but there are plans to publish at least source RPMS on DeepSpace6 some day.
Fedora 20 is the current developing platform, so use given hints above to create a RPM. Since Fedora 7 this package is included by default.
It's tested by the developer that creation of the RPM is working fine on RHEL 4.
RHEL/CentOS 5 has the package included by default.
RHEL/CentOS 6/7: release on EPEL planned for August 2014.
CentOS 5/6/7 are also platforms for regression tests.
Package is maintained, nevertheless, Funtoo is used as platform for regression tests.
Package is maintained, more information can be found at http://packages.debian.org/ipv6calc

only moderators are allowed to post
You can send bug reports to the author himself or subscribe to maillist “ipv6calc” and send it to the list.
The main program named “ipv6calc” is able to recognize many (not only) IPv6 address formats and depending on a selectable action (not required) a selectable output format can be specified. Also it has the capability to show detailed information of an IPv4/IPv6 address or anonymize it.
Option “-v” shows built-in features, depending on configuration before compiling:
$ ipv6calc -v ipv6calc: version 0.97.0 IP2Location GeoIP GeoIPv6 DB_AS DB_IPV4 DB_IPV6 DB_IPV4_AS DB_IPV6_AS DB_IPV4_CC DB_IPV6_CC DB_CC_REG DB_IEEE ANON_ZEROISE ANON_ANONYMIZE ANON_KEEP-TYPE-ASN-CC |

Note: since version 0.95.0 the internal layer for database usage was abstracted and each database “plugin” is initialized reporting then its supporting features in binary representation. This makes implementation of other external databases easier in the future. There are at least plans to create an overlay to built-in databases by publishing and use some “precompiled” newer databases replacing the need of recompilation for updated built-in databases.
A simple example is the conversion of an IPv6 address to a DNS PTR query string:
$ ipv6calc --out revnibbles.arpa 2001:db8::1 No input type specified, try autodetection...found type: ipv6addr 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa. |
Like you see, input format was autodetected. And the given example can be extended because ipv6calc also understands netmask / prefix length values:
$ ipv6calc -q --out revnibbles.arpa 2001:db8::1/64 0.0.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa. |
Also you've also learnt now that switch '-q' (quiet) suppresses informational messages. You can use this now to start a DNS PTR query using:
$ dig PTR `./ipv6calc -q --out revnibbles.arpa 2001:db8::1/64` |
But ipv6calc can do many more for you! Next example shows you the extraction of the IPv4 address contained in a 6to4 IPv6 address:
$ ipv6calc -q --action conv6to4 --in ipv6 2002:c0a8:fb61::1 --out ipv4 192.168.251.97 |
This also works vice-versa:
$ ipv6calc -q --action conv6to4 --in ipv4 192.168.251.97 --out ipv6 2002:c0a8:fb61:: |
There are many more features already implemented, if you miss one, send a note.
Information about a simple IPv6 address:
$ ipv6calc -q -i 3ffe:ffff::210:a4ff:fe01:2345 Address type: unicast, 6bone, global-unicast, productive Address type has SLA: 0000 Registry for address: reserved Interface identifier: 0210:a4ff:fe01:2345 EUI-48/MAC address: 00:10:a4:01:23:45 MAC is a global unique one MAC is an unicast one OUI is: XIRCOM |
Information about a Teredo IPv6 address:
$ ipv6calc -q -i 3ffe:831f:ce49:7601:8000:efff:af4a:86BF Address type: unicast, 6bone, global-unicast, productive, teredo IPv4 address: 80.181.121.64 IPv4 registry[80.181.121.64]: RIPENCC IPv4 address: 206.73.118.1 IPv4 registry[206.73.118.1]: ARIN Address type is Teredo and included IPv4 server address is: 80.181.121.64 and client port: 4096 IPv4 registry for Teredo server address: ARIN Registry for address: reserved |
There exists also a machine readable output (e.g. used by 'ipv6calcweb.cgi') - in addition, IP2Location and/or GeoIP information can be displayed, if databases are located on the system and supported.
$ ipv6calc -q -i -m 2a01:238:423d:8800:85b3:9e6b:3019:8909 IPV6=2a01:0238:423d:8800:85b3:9e6b:3019:8909 IPV6_ANON=a909:16fa:9091:a448:a909:4941:0000:0007 IPV6_TYPE=unicast,global-unicast,productive,iid-random,iid,iid-local IPV6_COUNTRYCODE=DE IPV6_AS_NUM=6724 IPV6_AS_TEXT=AS6724 STRATO STRATO AG IPV6_REGISTRY=RIPENCC SLA=8800 IID=85b3:9e6b:3019:8909 EUI64_SCOPE=local-random IP2LOCATION_COUNTRY_SHORT=DE IP2LOCATION_COUNTRY_LONG=GERMANY GEOIP_AS_TEXT=AS6724 STRATO STRATO AG GEOIP_COUNTRY_SHORT=DE GEOIP_COUNTRY_LONG=Germany GEOIP_LATITUDE=51.000000 GEOIP_LONGITUDE=9.000000 IP2LOCATION_DATABASE_INFO=IP2L-DB1 20130307 Copyright (c) 2013 IP2Location All Rights Reserved GEOIP_DATABASE_INFO=GEO-106FREE 20140506 Build 1 Copyright (c) 2014 MaxMind Inc All Rights Reserved / GEO-117 20130306 Build 1 Copyright (c) 2013 MaxMind Inc All Rights Reserved / GEO-536LITE 20140506 Build 1 Copyright (c) 2014 MaxMind Inc All Rights Reserved IPV6CALC_NAME=ipv6calc IPV6CALC_VERSION=0.97.0 IPV6CALC_COPYRIGHT="(P) & (C) 2001-2014 by Peter Bieringer <pb (at) bieringer.de>" IPV6CALC_OUTPUT_VERSION=7 IPV6CALC_SETTINGS_ANON="set=keep-type-asn-cc,mask-ipv6=56,mask-ipv4=24,mask-eui64=40,mask-mac=24,method=keep-type-asn-cc" IPV6CALC_FEATURES="IP2Location(dyn-load) GeoIP(dyn-load) GeoIPv6 ANON_ZEROISE ANON_ANONYMIZE ANON_KEEP-TYPE-ASN-CC DB_AS DB_IPV4 DB_IPV6 DB_IPV4_AS DB_IPV6_AS DB_IPV4_CC DB_IPV6_CC DB_CC_REG DB_IEEE" |
“ipv6calc” can run in filter mode to be able to extract from a huge list of IPv4/IPv6 addresses ones which are interesting or ones which are not interesting (see printout of online help below).
Filter tokens are the ones which are listed on “TYPE” lines shown in “-m -i” information mode.
Example for searching for Teredo addresses:
$ cat ip.bieringer.de-log.201310 | awk '{ print $1 }' | sort | uniq | ipv6calc -A filter -E teredo
2001:0:9d38:90d7:34f7:1a26:8599:e079 |
Note: since version 0.95.0 '-A filter' is optional if option '-E <filter expression>' is given (autoselected action).
Since version 0.40 new-style option handling was introduced, using
--in <inputtype>
--out <outputtype>
--action <actiontype>
and many more conversions were added. A built-in check matrix should prevent misconversions.
Up to version 0.39, only old-style options (aka “shortcut” options). They are one-in-all options, specifying input/action/output in one token. Internally this options will be converted into new-style options.
Online help always shows the currently implemented features.
IP2Location and GeoIP options only appear if compiled with such support.

$ ipv6logconv -h
ipv6logconv: version 0.97.0 CONV_REG CONV_IEEE
(P) & (C) 2002-2014 by Peter Bieringer <pb (at) bieringer.de>
General:
[-d|--debug <debug value>] : debug value (bitwise like)
[-q|--quiet] : be more quiet
[-n|--nocache] : disable caching
[-c|--cachelimit <value>] : set cache limit
default: 20
maximum: 200
Output:
[--out <output type>] : specify output type
addrtype : Address type
ouitype : OUI (IEEE) type
ipv6addrtype : IPv6 address type
any : any type
Takes data from stdin, proceed it to stdout |
A demonstration about which kind of statistics are possible to produce is shown at http://www.ipv6.bieringer.de/ (IPv6 only).
Example:
$ echo "2002:50b5:7940:0000:0000:0000:50b5:7940 - -" | ipv6logconv -q --out any RIPENCC.6to4.global-unicast.ipv6-addr.addrtype.ipv6calc |
See more examples inside the package.
On autoconfiguration, the interface part of an IPv6 address is based on the MAC address of the network interface card (NIC). This address is used for outgoing requests, if privacy option (RFC3041 / RFC4941) is not enabled. This results in many privacy related information on web- or mail-server log files. Administrators, which won't (be allowed to) store such information over time, but still do not want to loose information about address type distribution should use 'ipv6loganon' to anonymize their log files.
Since version 0.94.0 internally also IID anonymization is possible without loosing any information for “ipv6logstats”.
Since version 0.95.0 internally also prefix anonymization is possible without loosing any information for “ipv6logstats”.
The anonymizer would keep as much information as possible for IPv6 address types.
Client-side IID would be anonymized by
EUI-48 based: serial number would be zero'ed, keeping OID
EUI-64 based: serial number would be zero'ed, keeping OID
ISATAP: client IPv4 address would be anonymized by given IPv4 mask
TEREDO: client IPv4 address would be anonymized by given IPv4 mask, client port would be zero'ed
6to4(Microsoft): client IPv4 address would be anonymized by given IPv4 mask
local: whole IID would be zero'ed
Client-side SLA would be anonymized by
SLA would be zero'ed
Prefix would be anonymized by
6to4: client IPv4 address would be anonymized by given IPv4 mask
Compat/Mapped IPv4 addresses would be anonymized by
IPv4 address would be anonymized by given IPv4 mask
The anonymizer would keep as much information as possible for the IID of an IPv6 address.
Description from libipv6addr.h:
* IID anonymization is done by replacing with related information (64-bit) * xxxx:xxxx:xxxx:xxxC (C = 4-bit checksum) * * a9p9 4941 0000 000C -> RFC 4941 anonymized privacy extension Interface ID * * a9p9 4291 4xxx xxxC -> RFC 4291 anonymized EUI-48 Interface ID, xxx xxx = converted OUI * a9p9 4291 5xxx xxxC -> RFC 4291 anonymized EUI-48 Interface ID, xxx xxx = converted mapped IAB/OUI-36 * a9p9 4291 6xxx xxxC -> RFC 4291 anonymized EUI-64 Interface ID, xxx xxx = converted OUI * a9p9 4291 7xxx xxxC -> RFC 4291 anonymized EUI-64 Interface ID, xxx xxx = converted mapped IAB/OUI-36 * a9p9 4291 8xxx xxxC -> RFC 4291 embedded anonymized IPv4 address, xxx xxx = first 24 bit of included (anonymized) IPv4 address * a9p9 4291 c02d 5d1C -> RFC 4291 Chapter 2.5.1 anonymized static Interface ID * * a9p9 5214 4xxx xxxC -> RFC 5214 anonymized ISATAP Interface ID, xxx xxx = first 24 bit of included (anonymized) IPv4 address (local scope) * a9p9 5214 5xxx xxxC -> RFC 5214 anonymized ISATAP Interface ID, xxx xxx = first 24 bit of included (anonymized) IPv4 address (global scope) * a9p9 5214 cxx0 000C -> RFC 5214 anonymized ISATAP Interface ID, xx = first 8 bit of included vendor ID (local scope) * a9p9 5214 dxx0 000C -> RFC 5214 anonymized ISATAP Interface ID, xx = first 8 bit of included vendor ID (global scope) * a9p9 5214 exxx xxxC -> RFC 5214 anonymized ISATAP Interface ID, xxx xxx = first 24 bit of included extension ID (local scope) * a9p9 5214 fxxx xxxC -> RFC 5214 anonymized ISATAP Interface ID, xxx xxx = first 24 bit of included extension ID (global scope) * * a9p9 4843 0000 000C -> RFC 4843 anonymized ORCHID hash |
Depending on given mask, the part of the prefix will be replaced:
* SLA/NLA prefix part anonymization is done by replacing with pattern a909a909 * p = number of nibbles anonymized |
In addition to “anonymize” (of IID) this method anonymizes also the prefix of an IPv6 address or a whole IPv4 address by keeping ASN (Autonomous System Number, Country Code and Type).
Description from libipv6addr.h:
* Prefix anonymization in case of method=kp: p=0x0f * a909:ccca:aaaa:aaaC (C = 4-bit checksum) * ccc -> 10-bit Country Code mapping [A-Z]*[A-Z0-9] (936) * 0x3FF = unknown country * 0x000-0x3A7: c1= c / 36, c2 = c % 36 * aaaaaaaa -> 32-bit ASN |
Description from libipv4addr.h:
* Global IPv4 addresses are anoymized by storing country code and AS number * and using prefix of experimental range (240-255.x.y.z) * * 3 3 2 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1 * 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 * 1 1 1 1 * |p p p p| * Prefix * 0xF * * Pariy Bit (odd parity) * |P| * * Mapping of Country Code * |c c c c c c c c c c| * 10-bit Country Code mapping [A-Z]*[A-Z0-9] (936) * 0x3FF = unknown country * 0x000-0x3A7: c1= c / 36, c2 = c % 36 * * Mapping of ASN <= 65535 * 0|a a a a a a a a a a a a a a a a| * 16-bit ASN * * Mapping of ASN >= 65536, ASN & 0xE000 == 0 (12-bit LSB is ok) * 1|r r r|0|l l l l l l l l l l l l| * 13-bit LSB of ASN * * Mapping of ASN >= 65536, ASN & 0xE000 != 0 (12-bit LSB overflow) => unspecified * 1|r r r|1|0 0 0 0 0 0 0 0 0 0 0 0| * * Mapping of ASN registry for ASN >= 65536 * 0 0 0 = "unknown ASN registry" * 0 1 0 = APNIC * 0 1 1 = RIPE * 1 0 0 = LACNIC * 1 0 1 = AFRINIC * 1 1 0 = ARIN |
Currently native supported log files:
Apache log file format, 1st token is IPv4 or IPv6 address
There are plans to support also mail server log files sometimes in the future, but because of different formats, this would be probably done by a Perl program which parses the log file and a (cached) 'ip6calc' call with action 'anonymize'.

Takes data from stdin, outputs the processed data to stdout (default) |
$ cat /path/to/http_log | ./ipv6loganon >/path/to/http_log_anonymized |
(Supported since 0.90.0)
Adjust or add (note: more than one CustomLog directive is supported by Apache) httpd.conf like following:
CustomLog "|/usr/local/bin/ipv6loganon -a -f /var/log/httpd/access_log" combined |
In case of “cronolog” is used on the system, configure like this:
Apache version < 2.4:
CustomLog "|/usr/bin/ipv6loganon -f |/usr/sbin/cronolog /var/log/httpd/access.log-%Y%m%d" combined |
Apache version >= 2.4:
CustomLog "|$/usr/bin/ipv6loganon -f |/usr/sbin/cronolog /var/log/httpd/access.log-%Y%m%d" combined |
Because calling C programs directly as CGI isn't really recommended (too much security troubles all the time), I wrote a small wrapper utility which calls "ipv6calc" to get information about client and server address for displaying on a web page.
A demonstration about which kind of output is possible to produce is shown at
http://ip.bieringer.de/ (IPv4/IPv6)

This program parses a given webserver logfile and count addresses, useful for time period statistics.
Since version 0.95.0 it has extended output, adding a date/time line and statistics by Country Code and ASN (if required databases are available).

Major extensions/changes are listed here
Prefix and IID anonymization methods
Support of dynamic load of GeoIP and IP2Location libraries
Specifying dedicated GeoIP and IP2Location database files is now replaced by specifying dedicated database directories to make especially for GeoIP use of more database files.
ipv6calc/ipv6calcweb.cgi: enable included GeoIP support with IPv6 (usable with GeoIP >= 1.4.5)
ipv6calc: extend for 6rd support (--action 6rd_local_prefix --6rd_prefix <PREFIX> --6rd_relay_prefix <RELAY_PREFIX>)
ipv6calc: enable stdin support for bulk transformation
ipv6calc: add support for NAT64 address type
ipv6calc: add option “forceprefix <LENGTH>” to print prefix of an address without a given prefix length
ipv6loganon: extend for pipe usage (e.g. in Apache log file directive) and write/append to specified file
General: add configure options to disable built-in databases (reduce binary size a lot, e.g. for embedded devices)
