Synopsis

Domain Name manipulation library for Ruby

Description

• Parses a domain name ready for extracting the registered domain and TLD.

  require "domain_name"
  
  host = DomainName("a.b.example.co.uk")
  host.domain         #=> "example.co.uk"
  host.tld            #=> "uk"
  host.cookie_domain?("example.co.uk")    #=> true
  host.cookie_domain?("co.uk")            #=> false
  
  host = DomainName("[::1]")  # IP addresses like "192.168.1.1" and "::1" are also acceptable
  host.ipaddr?        #=> true
  host.cookie_domain?("0:0:0:0:0:0:0:1")  #=> true

• Implements rudimental IDNA support.
