I am not certain that the cost of doing TCP for this is worth the benefit of getting a signed priming response. I agree with section 2.4 - no DO bit. What does a DNSSEC-protected priming query gain you? Accepting any old priming query and having a root SEP configured, if the query is right all things work. If the query is wrong/forged you won't get anywhere any how. (Without going into the weeds here - what if one IP address were forged, what if it were 6, 16, or all of them?) (13 name servers => 13 A records + 7 AAAA records last check) Besides the warm and fuzzy feeling, what do you gain? (Keep in mind all of the TCP traffic it would take to get warm and fuzzy.)

Yes, you'll know sooner if a server's IP address is a problem, but you'd figure it out before it mattered anyway (if you ever use that server). -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Edward Lewis NeuStar You can leave a voice message at +1-571-434-5468 As with IPv6, the problem with the deployment of frictionless surfaces is that they're not getting traction.
