+# ip6addr [![Build Status](https://travis-ci.org/MichelBoucey/ip6addr.svg?branch=master)](https://travis-ci.org/MichelBoucey/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
