As with any argument that resorts to "elegance", it's a matter of taste. A single bit, which is already being sent though currently undefined, versus 32 bits that wouldn't otherwise need to be sent, and the unavoidable necessity of parsing OPT past the header. It just seems cleaner to me, and in the absence of other considerations it seems the obvious way to design a feature like this. (DNSSEC, by example, is a little bit like this: omitting some response data if a flag bit is not set.) However, other considerations do exist, and I'm not married to it. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
