    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
