Currently, atomic fragments are rare. You can easily see that many DNS servers are not doing any kind of PMTUD. They just fragment at 1280. What RFC-2460 effectively says is that if you are not doing PMTUD, then each and every outgoing packet has to be an atomic fragment. I'm not seeing that on todays IPv6 network. So that would be completely new. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
