The IPv6 Application Conversion Tools document provides information about:

1. conversion tools, utility software, and links to books, articles, and presentations on developing or converting programs written in languages including C/C++, Java, Python, Perl, and PHP that currently support only Internet Protocol version 4 (IPv4) to support both dual-stack (IPv4 and IPv6) or IPv6-only.

2. websites containing supplemental information.

3. tools such as the Hewlett-Packard (HP) ipv6sniff porting assistant, Microsoft Checkv4, Sun IPv6 Socket Scrubber, and later open source tools such as IPv6 CARE, IPv6finder, and PortToIPv6 Framework.

Some of the older tools and software may no longer be available from the original developers. Archival copies may be available from this IPv6 Knowledge Base administrator. Please contact ipv6-team [at]
