Hi: I'm now pulling together the final list of DHCPv4 options between 128 to 223 (inclusive) that are currently in use as per RFC 3942 (http://www.ietf.org/rfc/rfc3942.txt): "Reclassifying DHCPv4 Options". The 6-month notification period has expired. - Bernie Volz > ---

This would, as Ted indicates, greatly complicate the entire update sequence. The current update sequence (see draft-ietf-dhc-ddns-resolution-10.txt), never does a query of the RRs in the server. Therefore, either we'd have to do a query first to obtain the DHCID RR and extract the algorithm so we c

Pekka: Regarding your one major issue, the updater is NOT the entity that gets to decide whether to allow any DNS update to occur or not. It is the DNS server that restricts who can do updates and what they can update. We're assuming that the most likely entity to be given fairly open access to a

BTW, whatever algorithm you use (SHA-256 or even something much more complex) is not going to help -- it may make the work someone has to do a bit more involved, but it really doesn't make it impossible. 1. You always have a brute force attack. As you indicate, calculating the hash based on the ma

BTW: Just to be clear, the MD5 hash is calculated using both the client identifier AND the domain name. But the domain name is known (it is the entry under which the DHCID RR lives). However, this means that the DHCID data for a client changes with its name. The RDATA for all type codes other

How about we address issue 1 by expanding the DHCID RR type code. We have 16-bits and we're just using 4 values presently. There's plenty of room for future expansion *SHOULD* someone come along and demand a new algorithm in the future. I can't see why this would EVER occur since this really isn't
