Commandline tool to deal with IPv6 address text representations.

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

ip6addr

1. Purpose

ip6addr is a commandline tool that validates and generates IPv6 address text representations, based upon the library IPv6Addr :

• Canonical, in conformation with RFC 5952 (default output)
• Pure, i.e. force the rewriting of 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

2. Install

2.1. With Cabal

cabal install ip6addr

2.2. With Nix

2.2.1. From sources

nix-build

2.2.2. From Nix Packages collection

nix profile install nixpkgs#haskellPackages.ip6addr

3. Usage

ip6addr v2.0.0 (c) Michel Boucey 2011-2024

Usage: ip6addr [-v|--version]
               [(-c|--canonical) | (-n|--no-ipv4) | (-f|--full-length) |
                 (-p|--ptr) | (-w|--windows-unc) | (-r|--random)]
               [-q|--quantity ARG] [-s|--prefix ARG] [-d|--no-newline]
               [IPv6 address]

  ip6addr

Available options:
  -v,--version             Show version
  -c,--canonical           In conformation with RFC 5952 (default output)
  -n,--no-ipv4             Force the rewriting of the IPv4 address if present to
                           get a pure IPv6 address made of nibbles only
  -f,--full-length         Full IPv6 address length
  -p,--ptr                 PTR reverse mapping
  -w,--windows-unc         Windows UNC path name
  -r,--random              Random generation
  -q,--quantity ARG        Amount of random addresses to generate
  -s,--prefix ARG          Set a prefix for random addresses to generate
  -d,--no-newline          Do not output trailing newlines
  -h,--help                Show this help text

N.B. : In version 2, flags and arguments have changed from version 1, but the main features are identical.
