domain_name

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
    

Caveats

  • It does not currently perform the strict domain label validation defined in RFC 5891 and 5892. It is being worked on on the unicode branch.
