RFC 2929 • RFC 2929 Provided first IANA considerations for RR TYPEs, CLASSes, RCODEs, OpCodes, header bits, etc. • RFD 2929 generally provides some Private Use, some Publication Required, some IETF Consensus, and few reserved or Standards Action required allocation policies. IETF DNSEXT
RFC 2929 (cont.) • Main Problem: • “IETF Consensus” and even “Specification Required” were considered too hard for allocating Type Codes in a timely fashion, so people overload TXT, etc. • Solution History • There initially appeared to be a strong desire for a liberalized version of “Early Allocation” (RFC 4020) which was put in draft -00. • Then there was a backlash at the Paris meeting against “Early Allocation” and for “Expert Review” resulting in draft -01. • In Vancouver, feelings seemed a bit more positive but there was a desire for more explicit guidance for the Expert. IETF DNSEXT
RFC 2929bis • Primary Effect: Replace RFC 2929 with a more liberal document • draft-ietf-dnsext-2929bis-02.txt will be submitted next week, available at www.pothole.com/~dee3 • Changes to RFC 2929 (see Appendix to draft): • Replace “IETF Consensus” for RR Type Codes with “Expert Review” as described on later slides. • Cover AFSDB Subtypes allocation using IETF Consensus. • Augments some “IETF Standards Action” required with “as modified by [RFC 4020]”. • Provides for hypothetical future “meta-CLASSes”. • Numerous minor updates and changes. IETF DNSEXT
RFC 2929bis DNS Type Allocation Policy • About half of the RR Type Codes can be allocated with Expert Review. Most of the other half is “Specification Required”. • Expert Review only available • After a completed DNS RR Type Allocation Template has been posted for at least three weeks on the namedroppers mailing list. • The RR for which a TYPE code is being requested must be either (a) a data TYPE which can be handled as an Unknown RR as described in [RFC 3597] or (b) a Meta TYPE who processing is optional, i.e., which it is safe to simply discard. IETF DNSEXT
DNS RR Type Parameter Allocation Template • Date • Name, telephone, and email of originator • Pointer to public RR description document • Need for new RR Type? • Closest existing RR Type • Does new RR Type require special handling different from an Unknown RR Type or an ignorable meta-Type?
