Commandline tool to deal with IPv6 address text representations.

Commandline tool to validate, canonize and generate IPv6 address text representations

ip6addr

A commandline tool that validates and generates IPv6 address text representations

• Canonical, in conformation with RFC 5952 (default output)
• Pure, i.e. rewriting IPv4 address if present
• Full length
• Reverse lookup domain name, in conformation with RFC 3596 Section 2.5
• Windows UNC path name
• Random generation for test purpose
