Let's see, millions of full-service resolvers, times the packet-count differential between UDP and TCP, times the average reload/restart frequency of those full-service resolvers per day/week/month. Can't a case be made from sheer volume?

Although the existence of the "general desire" might be debatable, I think Shane has a valid point. The requirement level of the TCP support has been already tightened in RFC5966 (from a SHOULD in RFC1123 to REQUIRED), so it doesn't make much sense to me to use a MUST in this document referring to the older RFC. At the very least, if we want to keep the MUST, there should be a different reason than the reference to RFC1123. -- JINMEI, Tatuya _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
