ipv6calc will do some format changes and calculations for you (P) & (C) 2001-2024 by Peter Bieringer <pb (at) bieringer.de> published under GNU GPLv2 For suggestions and bug report please contact author More help is available using 'ipv6calc -?' Intention: * This utility can be used by the IPv6 enabled initscripts for better duplicate address detection on setup of IPv6 addresses * Also migrate "ip6_int" of Keith Owens <[email protected]> into this utility Known bugs: * ipv6calc is sure not the securest C program around the world Contents: * "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) * "mod_ipv6calc": Apache module Included internal databases: * IEEE IAB, OUI, OUI-36 databases (for decoding vendor part of MAC/EUI-48/EUI-64) * IPv4 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv4 anonymization) * IPv6 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv6 anonymization) * ASN assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for IPv4/IPv6 anonymization) Supported external databases: * GeoIP(MaxMindDB) - internally handled as GEOIP2 * IP2Location * DB-IP.com(MaxMindDB) - internally handled as DBIP2 Where to get: Homepage: https://www.deepspace6.net/projects/ipv6calc.html Latest version of sources: ftp://ftp.bieringer.de/pub/linux/IPv6/ipv6calc/ http://www.bieringer.de/ftp/pub/linux/IPv6/ipv6calc/ https://www.bieringer.de/ftp/pub/linux/IPv6/ipv6calc/ ftp://ftp.deepspace6.net/pub/ds6/sources/ipv6calc/ http://www.deepspace6.net/ftp/pub/ds6/sources/ipv6calc/ https://www.deepspace6.net/ftp/pub/ds6/sources/ipv6calc/ GitHub access: https://github.com/pbiering/ipv6calc Available formats: tar.gz spec-file is included, so you can build an RPM from source tarball using rpm -ta ipv6calc-version.tar.gz Ready to use packages for several operating systems: Linux: Fedora (https://src.fedoraproject.org/rpms/ipv6calc) Core 6: initial developing platform, so use given hint above to create a RPM since 7: package is included Enterprise Linux (https://src.fedoraproject.org/rpms/ipv6calc / https://koji.fedoraproject.org/koji/packageinfo?packageID=366): EL3: build from source package potentially still work but not tested anymore, OS is EOSL EL4: build from source package potentially still work but not tested anymore, OS is EOSL EL5: build from source package potentially still work but not tested anymore, OS is EOSL EL6: build from source package potentially still work but not tested anymore, OS is EOSL EL7: package is available via EPEL EL8: package is available via EPEL EL9: package is available via EPEL Mandrake (EOSL): similar to Red Hat, rebuild should work, too Debian: maintained package at http://packages.debian.org/ipv6calc Ubuntu: maintained package at http://packages.ubuntu.com/ipv6calc or http://packages.ubuntu.com/cgi-bin/search_packages.pl?searchon=names&version=all&exact=1&keywords=ipv6calc BSD: NetBSD: ftp://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/net/ipv6calc/README.html FreeBSD: http://www.freshports.org/net-mgmt/ipv6calc/ (http://www.freebsd.org/cgi/query-pr.cgi?pr=34441) OpenBSD: http://www.openbsd.org/cgi-bin/cvsweb/ports/net/ipv6calc/ Mailing lists: ipv6calc-announce Reason: sending announcements of new versions Traffic: very low Postings: only moderators are allowed to post, others are rejected automatically Subscription: https://lists.deepspace6.net/postorius/lists/ipv6calc-announce.lists.deepspace6.net/ ipv6calc Reason: discussions Traffic: medium Postings: only subscribers are allowed to post Subscription: https://lists.deepspace6.net/postorius/lists/ipv6calc.lists.deepspace6.net/
According to the docs I can do this:
$ ipv6calc --out ipv6 --examples
--forceprefix <num>: Force prefix to <num>
--no-prefixlength: Don't print prefix length if given on input
However those two options don't seem to work:
$ ipv6calc --in prefix+mac "1:2:3:4::/56" "11:22:33:44:55:66" --action prefixmac2ipv6 --out ipv6addr --no-prefixlength
ipv6calc: unrecognized option '--no-prefixlength'
$ ipv6calc --in prefix+mac "1:2:3:4::" "11:22:33:44:55:66" --action prefixmac2ipv6 --out ipv6addr --force-prefix 56
ipv6calc: unrecognized option '--force-prefix'
The other options listed in --examples
work.
While contrib/ipv6calc.spec is generated from contrib/ipv6calc.spec.in, the pregenerated file is shipped in the source tree and resulting tarball. This is unlike e.g. Makefiles, that are also generated from Makefile.in, but in this case no pregenerated Makefiles being shipped.
This results into a dirty source tree when running "make; make clean" and requires workarounds in the Debian package.
At a few points throughout configure.in
, the macro AC_ARG_ENABLE()
is incorrectly used. The parameters should be interpreted as follows:
AC_ARG_ENABLE(option-name, help-string, action-if-present, action-if-not-present)
but instead it seems that you are interpreting the 3rd and 4th parameters as what to do if the option is enabled and what to do if it is disabled, respectively. An example of this problem is at line 1440 where you have
AC_ARG_ENABLE([mod_ipv6calc],
AS_HELP_STRING([--enable-mod_ipv6calc],
[Enable build of mod_ipv6calc for Apache (default: disabled)]),
[
ENABLE_MOD_IPV6CALC="1"
],[
ENABLE_MOD_IPV6CALC="0"
])
This leads to the result that ./configure --disable-mod_ipv6calc
actually enables mod_ipv6calc, as does ./configure --enable-mod_ipv6calc
. The only way to disable this option is to NOT pass either --disable-mod_ipv6calc
nor --enable-mod_ipv6calc
.
To fix this, the 3rd parameter above should be changed from ENABLE_MOD_IPV6CALC="1"
to ENABLE_MOD_IPV6CALC="$enable_mod_ipv6calc"
, and the 4th parameter can be left as is if you want --disable_mod_ipv6calc
to be the default if this flag is not passed.
I did make your team aware of this some years ago, and sent a patch (if memory serves), but it seems that the same erroneous logic is being re-introduced. Take a look at (say) the db-ipv4
option on line 366 for a correct example.
Also, to modernize things, you should rename configure.in
-> configure.ac
. The former name has been deprecated for years.
Though I had succeeded at compiling the code from git in recent past, the recent code fails to compile due to unused parameter errors.

At present you cannot extract the EUI64 or MAC component from an IPv6 address:
ipv6calc --in ipv6 2001:db8::a8bb:ccff:fedd:eeff --out eui64
Specify proper action or input for output format: eui64
$ ipv6calc --in ipv6 2001:db8::a8bb:ccff:fedd:eeff --out mac
No valid MAC address given!
However if you use --showinfo
then both these values are extracted:
ipv6calc --in ipv6 2001:db8::a8bb:ccff:fedd:eeff --showinfo
Interface identifier: a8bb:ccff:fedd:eeff
EUI-48/MAC address: aa:bb:cc:dd:ee:ff
It would be very helpful if we could extract these values without scraping the --showinfo
output.
My reason for requesting this feature is that I would like to take an internal IPv6 address from DNS for a number of hosts on my LAN, extract the EUI64 or MAC component of each, and then append that onto a routable IPv6 prefix from my ISP in order to construct a valid global IPv6 address for each host. I then plan to update DNS records with these newly constructed global IPv6 addresses, so that when my router's IPv4 address changes, all my hosts get their DNS entries updated with their new public IPv6 addresses.
Essentially, I have an IPv6 address and I want to replace the prefix on it with a different prefix. For example, I have the private IP fd00::1234
and I should remove the fd00::/64
prefix, then replace it with the 2001:db8:aaaa:bbbb::/64
prefix instead, to produce the public address 2001:db8:aaaa:bbbb::1234
. The prefix is a 6rd one generated from my ISP's IPv6 prefix and my IPv4 address.
I can use ipv6calc to convert the IPv4 address into a valid 6rd prefix, however there doesn't seem to be a way to replace the prefix on a private IPv6 address with a public prefix, or to extract the EUI64/MAC so you can use string concatenation to replace the prefix either.

http://www.deepspace6.net/ says "ipv6calc 1.0.0 was released" but on GitHub the latest release (https://github.com/pbiering/ipv6calc/releases/latest) shows as 0.99.2 (https://github.com/pbiering/ipv6calc/releases), which confuses the Homebrew livecheck system.
Thanks!
In ipv6calc-db-update.sh, the "skip_download" variable is always set to "true", so it won't download any files. The variable should be set to "false" by default, and only assigned "true" when the "-s" switch is provided.

*** Error code 1
"make install" seems to be installing all of the files under "tools" to (e.g.) /usr/share/ipv6calc/tools.
However, most of these seem to be internal, source-level tools, e.g. regenerating header files out of IEEE databases and such, and are not really useful in the "destionation" system or in /usr.
A real-world problem that arises with this is when building ipv6calc for a distribution, such as Debian.
The current DBIP source only implements the free databases, as well as the DBIP-Generate.pl script. Is it possible to get them working with the full version from DBIP to improve the output?
I wanted to contact you about looking into the changes since any modifications would be something you could do faster then others being the author of the code.
current "master" contains now support for OpenSSL 3 which deprecated the really old MD5 functions.
But after switching to new EVP MD5 functions, static build reports a warning, don't know how to solve this proper.

Hi,
I have a list with some IPv6 addresses I would like to put them into perspective.
I would like to specify to which of those assignment a specific IP belongs.
http://www.iana.org/assignments/ipv6-unicast-address-assignments/ipv6-unicast-address-assignments.xhtml
What I need to do for that is making a comparison of a given network prefix like 2001:0600::/23 and see if my specific IP address belongs to that range.
Is there any way your toolkit can do this for me? If not, do you have any suggestions for me?

Build reproducibility is the concept that builds in equivalent build environments should result in the same output. https://reproducible-builds.org/ has more information.
I'd recommend avoiding this fprintf altogether.

Compressed IPv6 addresses are formatted as per RFC 1884 section 2.2, which is arguably unclear about whether a single zero should be replaced by ::
. (Even though RFC 1884 does say "[the] use of "::" indicates multiple groups of 16-bits of zeros", with the most common interpretation of "multiple" being "> 1".)
However RFC 1884 was obsoleted by successive versions of "IP Version 6 Addressing Architecture", with the latest being RFC 4291 (which explicitly allows for both :0:
and ::
). But RFC 4291 was (according to IETF) updated by (among others) RFC 5952 and while the latter is titled "Recommendation", in section 4.2.2 it explicitly disallows using ::
to replace a single zero:
The symbol "::" MUST NOT be used to shorten just one 16-bit 0 field.
For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but
2001:db8::1:1:1:1:1 is not correct.
It would seem to me like the only code change necessary in ipv6calc
would be to bump this >= 0
test to >= 1
. (And maybe simplify the logic a bit. And rename the file from librfc1884.c
to librfc5952.c
.)
For context, we are running into issues string matching (within Prometheus labels) IPv6 addresses generated by Rust library code (that implements RFC 5952) with ones generated by ipv6calc
for about half the IP addresses we use (which have exactly one zero segment). And make it impossible to match the instance
label of our process with that of node-exporter
, so we're "missing" machine metrics for about half our instances.
It took me a while to figure out how to regenerate the ipv6calc.html
file from the source ipv6calc.lyx
file. I'm filing this to document this for others, and perhaps as a feature enhancement request for doc/generate.sh
:
This is a two step process: first, the Lyx file is generated to an SGML. Second, the SGML to the HTML. (Note: I have not figured out what the purpose of the XML file in the source tree is.).
Only the second step is actually in generate.sh
.
apt install lyx docbook-utils
cd doc && lyx --export docbook ipv6calc.lyx
The build system seems to be using "jade", but this is an old piece of software that has been forked in the meantime. Replacing "jade" with "openjade" seems to work just fine.
apt install opensp openjade docbook docbook-dsssl
cd doc && onsgmls -s ipv6calc.sgml
(This is optional and just validates the SGML. ./generate.sh
does this)cd doc && openjade -t sgml -i html -V nochunks -d "ldp.dsl#html" ipv6calc.sgml > ipv6calc.html
(./generate.sh
does this)As an alternative:
apt install ldp-docbook-dsssl
cd doc && openjade -t sgml -i html -V nochunks -d "docbook/stylesheet/dsssl/ldp/ldp.dsl#html" ipv6calc.sgml > ipv6calc.html
(in this case, doc/ldp.dsl
is not necessary and can be removed)ldp here stands for "Linux Documentation Project", and the ldp.dsl file is almost a pristine copy compared to the system copy as shipped in the ldp-docbook-dsssl package.
This was under a Debian sid with Lyx v2.3.7, Docbook 4.5, Docbook-utils 0.6.14, Docbook-DSSSL 1.79, OpenJade 1.4devel1, opensp 1.5.2
While autoconf (./configure) seems to be obeying CPPFLAGS from the environment, this does not seem to be used by Makefile etc. when building .c files to .o.
(Note: I see that in master the CPPLAGS -> CPPFLAGS typo has been fixed. This is unrelated.)
Distributions often pass default build flags through both CFLAGS and CPPFLAGS, as appropriate. For example, Debian, when the "foritfy" hardening flag is enabled, passes "-D_FORTIFY_SOURCE=2" to CPPFLAGS. The build system seems to entirely ignore this right now, requiring the use of workarounds.
Separately, I don't understand the DEFAULT_CFLAGS variable. Given one can pass CFLAGS to ./configure through the environment, why employ an additional variable?

This is likely due to an older version of GnuPG as I think newer versions have improved defaults.
But you can override the defaults using --personal-cipher-preferences

I have to admit that I have lust in my heart to be able to lift bits of ipv6calc into a simpler library mostly dedicated to dealing with prefix pools quickly (sse2 and arm intrinsics for the fast stuff). But to do that, I'd have to license it LGPL, and it looks as though ipv6calc the program is GPLv2 (which is fine) and most of the libraries could be LGPL, except that they aren't.
