IpFormat

This is a gem that leverages the Resolv library to validate IP addresses. This can handle both, IPV4 and IPV6.

Installation

Add this line to your application's Gemfile:

gem 'ip_format'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ip_format

Usage

In order to validate an attribute, use the validates keyword:

class Device < ActiveRecord::Base

  # ...

  validates :ip, ip_format: true

  # ...

end

Now the ip attribute will be validated:

Device.new(ip: 'invalidip').valid?        # => false
Device.new(ip: '192.68.0.1').valid? # => true

Also, the model in question doesn't need to inherit from ActiveRecord::Base, you only need to include ActiveModel::Validations in your class:

require 'ip_format'

class Awesome
  include ActiveModel::Validations
  attr_accessor :ip
  validates :ip, ip_format: true
end

awesome = Awesome.new

awesome.ip = "fde4:8dba:82e1::"
awesome.valid? # => true

awesome.ip = "invalidip"
awesome.valid? # => false
