def validate_each(record, attribute, value)
  # In Rails 4.0.0, ip_address will be nil if an invalid IP address was assigned.
  # https://github.com/jetthoughts/rails/commit/0aa95a71b04f2893921c58a7c1d9fca60dbdcbc2

  # BUT: in Rails 4.0.1, validators don't get a chance to
  # run before IPAddr::InvalidAddressError is raised.
  # I don't see what broke it in rails 4.0.1...
  # So this validator doesn't actually do anything anymore.
  # But let's keep it in case a future version of rails fixes the problem and allows
  # validators to work on inet and cidr columns.
  record.errors.add(attribute, :invalid) if record.ip_address.nil?
