My guess > would be the latter.) I believe the latter. RFC3596 redefines query types that trigger type A additional section processing to also perform type AAAA additional section processing. However, the server is only required to return records it already has, not to perform additional queries to obtain records it does not have. So, it's fairly easy to construct a scenario in which A records are returned but AAAA records are not, even though they exist. IMHO this is unfortunate, since it means that the round-trip savings realized by use of the additional section are lost in many cases. -- Jeff ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos
