Yes, we have been informed that the the servers, ns{1,2}.obol-net.net are running Novell 5.0 and 5.1, respectively (or the other way around). > As Eric has just pointed out (as I was writing this), this tells BIND (and > DJBDNS) "I do not have this answer, but the answer can be found at my > nameserver". I tested a server which I think is an NT (non-bind) server, which permits recursion. It accepts the respons from the Novell server without SERVFAIL: ; <<>> DiG 2.2 <<>> @ns1.ballou.se ns1.obol-net.net mx ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10 ;; flags: qr aa ra; Ques: 1, Ans: 0, Auth: 2, Addit: 2 ;; QUESTIONS: ;; ns1.obol-net.net, type = MX, class = IN ;; AUTHORITY RECORDS: obol-net.net. 86400 NS ns2.obol-net.net. obol-net.net. 86400 NS ns1.obol-net.net.
