  11.3.  Examples

     The following addresses

               fe80::1234 (on the 1st link of the node)
               ff02::5678 (on the 5th link of the node)
               ff08::9abc (on the 10th organization of the node)

     would be represented as follows:

               fe80::1234%1
               ff02::5678%5
               ff08::9abc%10

     (Here we assume a natural translation from a zone index to the
     <zone_id> part, where the Nth zone of any scope is translated into
     "N".)

     If we use interface names as <zone_id>, those addresses could also be
     represented as follows:

              fe80::1234%ne0
              ff02::5678%pvc1.3
              ff08::9abc%interface10

     where the interface "ne0" belongs to the 1st link, "pvc1.3" belongs
     to the 5th link, and "interface10" belongs to the 10th organization.

  options for isURL method

  require_protocol - if set to true isURL will return false if protocol is not present in the URL.
  require_host - if set to false isURL will not check if host is present in the URL.
  require_port - if set to true isURL will check if port is present in the URL.
  require_valid_protocol - isURL will check if the URL's protocol is present in the protocols option.
  allow_underscores - if set to true, the validator will allow underscores in the URL.
  host_whitelist - if set to an array of strings or regexp, and the domain matches none of the strings
                   defined in it, the validation fails.
  host_blacklist - if set to an array of strings or regexp, and the domain matches any of the strings
                   defined in it, the validation fails.
  allow_trailing_dot - if set to true, the validator will allow the domain to end with
                       a `.` character.
  allow_protocol_relative_urls - if set to true protocol relative URLs will be allowed.
  allow_fragments - if set to false isURL will return false if fragments are present.
  allow_query_components - if set to false isURL will return false if query components are present.
  disallow_auth - if set to true, the validator will fail if the URL contains an authentication
                  component, e.g. `http://username:password@example.com`
  validate_length - if set to false isURL will skip string length validation. `max_allowed_length`
                    will be ignored if this is set as `false`.
  max_allowed_length - if set, isURL will not allow URLs longer than the specified value (default is

    This function does not check against all the media types listed
