RFC 2535, Domain Name System Security Extensions, March 1999

3.1.3 The Protocol Octet

   It is anticipated that keys stored in DNS will be used in conjunction
   with a variety of Internet protocols.  It is intended that the
   protocol octet and possibly some of the currently unused (must be
   zero) bits in the KEY RR flags as specified in the future will be
   used to indicate a key's validity for different protocols.

   The following values of the Protocol Octet are reserved as indicated:

        VALUE   Protocol

          0      -reserved
          1     TLS
          2     email
          3     dnssec
          4     IPSEC
         5-254   - available for assignment by IANA
         255     All

   In more detail:
        1 is reserved for use in connection with TLS.
        2 is reserved for use in connection with email.
        3 is used for DNS security.  The protocol field SHOULD be set to
          this value for zone keys and other keys used in DNS security.
          Implementations that can determine that a key is a DNS
          security key by the fact that flags label it a zone key or the
          signatory flag field is non-zero are NOT REQUIRED to check the
          protocol field.
        4 is reserved to refer to the Oakley/IPSEC [RFC 2401] protocol
          and indicates that this key is valid for use in conjunction
          with that security standard.  This key could be used in
          connection with secured communication on behalf of an end
          entity or user whose name is the owner name of the KEY RR if
          the entity or user flag bits are set.  The presence of a KEY
          resource with this protocol value is an assertion that the
          host speaks Oakley/IPSEC.
        255 indicates that the key can be used in connection with any
          protocol for which KEY RR protocol octet values have been
          defined.  The use of this value is discouraged and the use of
          different keys for different protocols is encouraged.
