 8. DNS Packet Format

         The packet format for the NAPTR record is:

                                          1  1  1  1  1  1
            0  1  2  3  4  5  6  7  8  9  0  1  2  3  4  5
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          |                     ORDER                     |
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          |                   PREFERENCE                  |
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          /                     FLAGS                     /
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          /                   SERVICES                    /
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          /                    REGEXP                     /
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+
          /                  REPLACEMENT                  /
          /                                               /
          +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+

    where:

   FLAGS A <character-string> which contains various flags.

   SERVICES A <character-string> which contains protocol and service
      identifiers.

   REGEXP A <character-string> which contains a regular expression.

   REPLACEMENT A <domain-name> which specifies the new value in the
      case where the regular expression is a simple replacement
      operation.

   <character-string> and <domain-name> as used here are defined in
   RFC1035 [1].
