This is the ip Address Converters project
This project was registered on SourceForge.net on Aug 17, 2013, and is described as follows:
ipv6 converters were required for a another project inbits but inet_ntop and inet_pton were not available in compiler package being used, and proved difficult to get/install. So these were written, intially in Qt.C++ and Python, later in C Perl Ruby php and Tcl.
C and Qt.C++ use two element array of uint64_t integers, for ipv6 and
a single uint32_t for ipv4.
Ruby, Tcl-8.5, and Python use their built in integer types. which cope with (2^128)-1.
Perl-ipv4 uses inbuilt integer type. Perl ipv6 routines use Math::BigInt => try gmp.
php uses gmp numbers.
