Both IPv4 and IPv6 are supported. [![Build Status](https://travis-ci.org/ruby/ipaddr.svg?branch=master)](https://travis-ci.org/ruby/ipaddr) ## Installation This library is part of the standard ruby distribution as default gem and synchronized periodically, but you can explicitly depend on this gem with version constraints as necessary, like when you need a newer version than comes with older versions of ruby. For example, you can add this line to your application's Gemfile: ```ruby gem 'ipaddr', '~> 1.2' ``` And then execute: $ bundle Or install it yourself as: $ gem install ipaddr ## Usage ```ruby require 'ipaddr' ipaddr1 = IPAddr.new "3ffe:505:2::1" p ipaddr1 #=> # p ipaddr1.to_s #=> "3ffe:505:2::1" ipaddr2 = ipaddr1.mask(48) #=> # p ipaddr2.to_s #=> "3ffe:505:2::" ipaddr3 = IPAddr.new "192.168.2.0/24" p ipaddr3 #=> # ``` ## Alternative The [ipaddress](https://rubygems.org/gems/ipaddress) gem is a popular, extensive library for manipulating IP addresses with a layer of compatibility with `ipaddr`. If you need a richer set of features than `ipaddr` has, try this library instead. ## Development After checking out the repo, run `bundle install` to install dependencies. Then, run `rake test` to run the tests. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/ruby/ipaddr. ## License The gem is available as open source under the terms of the [2-Clause BSD License](https://opensource.org/licenses/BSD-2-Clause). ipaddr-1.2.5/lib/0000755000004100000410000000000014346440171013564 5ustar www-datawww-dataipaddr-1.2.5/lib/ipaddr.rb0000644000004100000410000005114314346440171015360 0ustar www-datawww-data# frozen_string_literal: true # # ipaddr.rb - A class to manipulate an IP address # # Copyright (c) 2002 Hajimu UMEMOTO . # Copyright (c) 2007, 2009, 2012 Akinori MUSHA . # All rights reserved. # # You can redistribute and/or modify it under the same terms as Ruby. # # $Id$ # # Contact: # - Akinori MUSHA (current maintainer) # # TODO: # - scope_id support # require 'socket' # IPAddr provides a set of methods to manipulate an IP address.
