> 3) {any|all} open question...can a server be "partially lame?"Sadly, yes, ref. suspected load balancers who have been taught how to reply to A queries, but return empty non-AA answers (possibly with authority information) when queried for other record types, such as AAAA, ref. dig @ns4.bpldns.com. lzd.jshsos.ksyunv5.com. a vs. dig @ns4.bpldns.com. lzd.jshsos.ksyunv5.com. aaaa (this example came up earlier in the discussion, just repeating it here as an example) See the results of querying for "ns" or "soa", they are also non-AA but with a authority section among others pointing to itself, similar to the result for the "aaaa" query.
