# custom full domain length and label length
validates :domain_name, :domain => { :length => 200, :label_length => 60 }

Ip Address Validator

# validate ip address
validates :ip, :ip_address => true

# ip address allowed with prefix
validates :ip, :ip_address => { :allow_prefix => true }

# allows only IPv4
validates :ip, :ip_address => { :only => :ipv4 }

# allows only IPv6
validates :ip, :ip_address => { :only => :ipv6 }

validates :ip, :ip_address => { :message => "custom message" }

Localization Tricks

To customize error message, you can use { :message => "your custom message" } or simple use Rails localization en.yml file, for instance:

en:
  errors:
    messages:
      domain:
        length: "your custom length error message"
     ip_address:
       invalid:
         general: "your custom invalid ip address error message"
  activemodel:
    errors:
      messages:
        domain:
          invalid: "custom error message only for activemodel"
       models:
         your_model:
           domain:
             invalid: "custom error message for YourDomain model"
