Fixed in CVS by extending the Makefile(.in) to make IP2Location support optionally. Also committed IP2Location C-API 1.1.0 to CVS.

IP2Location support added to ipv6calc
by Peter Bieringer 07 Jun '06

07 Jun '06

Hi, in March I've implemented IP2Location support to ipv6calc. See here for more information: http://www.ip2location.com In March 2006, the support of IPv6 was still missing in C API. Unfortunately, last status I get some days ago has't changed, they are out of manpower and missing demand to implement it soon. Anyway, I committed the changes now to CVS, for IPv4, IP2Location support is already working. Here the changelog since the last release (0.51): 20060607/PB lib/librfc1924.c - replace conversion code with clean reimplementation created by Niko Tyni because of unknown license issue of the old piece of code update databases 20060317/PB databases/ipv6-assignment/create-registry-list.pl databases/ipv4-assignment/create-registry-list.pl databases/ipv6-assignment/dbipv6addr_assignment.h databases/ipv4-assignment/dbipv4addr_assignment.h lib/libipv6addr.h lib/libipv4addr.h - store also prefix length in lookup table update databases 20060316/PB lib/libipv4addr.c - fix wrong use of () in ipv4addr_setword 20060306/PB Makefile.in ipv6calc/Makefile.in ipv6calc/ipv6calc.c ipv6calc/showinfo.c - add support for IP2Location lib/ipv6calcoptions.h - add new option: -p <path to IP2Location database> 20060213/PB ipv6calc/Makefile.in - replace "make" by "${MAKE}" (forgotten in 20051119) Please try it.

ipv6calc BUG: --printuppercase doesn't work.

ipv6calc BUG: --printuppercase doesn't work. It is documented to work in version 0.45 and 0.50, but it does not work. --uppercase (the old option?), however, does.

Each option could be given a short one letter abbreviation, such as -i for --in, -o for --out, -6 for --ipv6addr, -U for --printuppercase, -u for --printuncompressed, and -f for --printfulluncompressed, so the above command would become ipv6calc -qo6fU 'Itq!EN%BS(OvEV3?2kP!'. ( -qo6fUi8 would be -q --out ipv6addr --fulluncompressed --printuppercase --in base85, and likewise -qi8o6fU would be -q --in base85 --out ipv6addr --printfulluncompressd --printuppercase.) I think ipv6calc is a perfect example case study in what's wrong with long options. They are insane. Sincerely, Brad Allen <ULMO(a)SONIC.NET>

Hi, I've added support for AfriNIC registry and Teredo addresses, extend registry information generation for IPv6 like in IPv4, and fix a bug detecting the local unicast addresses (which affects also detection of link-local addresses - stupid bug). Current ChangeLog: 20051026/PB restructure registry database directory - process now registry files 2 days ago to prevent problems short after local day switches add support for new registry AFRINIC extend IPv6 registry data from 32 to 64 bits, adapt related function in lib/libipv6addr 20051021/PB lib/libipv6addr - fix bug for unique local unicast detection ipv6calc/showinfo - minor review ipv6calcweb.cgi - updates according to changes of showinfo.c 20051020/PB lib/libipv6addr ipv6calc/showinfo ipv6logconv ipv6logstats - add support for Teredo addresses 20050916/PB various make files - add missing entries to fullfil NetBSD's make Please run tests, I plan to release the new version this weekend.

Hi, sorry, but I had no luck with 0.49, there were some stack overflow and off-by-one bugs sleeping since longer time, but now rising up during compiling with some protection options. Many credits to Radek Vokál for finding bugs and pointing out the snprintf size problems. Therefore I released now version 0.50: Available at: <ftp://ftp.bieringer.de/pub/linux/IPv6/ipv6calc/> (and via CVS - note that DS6 currently contain only older versions). Not-minor changes: 20050915/PB various c files - fix snprintf size parameter (credits to Radek Vokál for pointing this out) lib/libipv6addr.c#ipv6addr_copy - fix bug which causes stack overflow (credits to Radek Vokál for finding the bug) several Makefiles - add compiler switch -O2, reason for segfault was found - remove also static on clean ipv6logconv: - add support for unique local unicast update databases Happier using now...
