So trying the 'other' listed NServers above: That's wrong of course; it is returning two A RRs for mail.wtplaw.com. however a) they always show 3 (three!) seconds TTL on those records, and b) these two NS, lp1.wtplaw.com. and lp1.wtplaw.com. , aren't shown as authoritative, and c) aren't even auth. / don't work for themselves! ======= smithi on paqi% dig @lp1.wtplaw.com. lp1.wtplaw.com. ; <<>> DiG 9.3.4 <<>> @lp1.wtplaw.com. lp1.wtplaw.com. ; (1 server found) ;; global options: printcmd ;; connection timed out; no servers could be reached smithi on paqi% dig @lp2.wtplaw.com. lp2.wtplaw.com. ; <<>> DiG 9.3.4 <<>> @lp2.wtplaw.com. lp2.wtplaw.com. ; (1 server found) ;; global options: printcmd ;; connection timed out; no servers could be reached ======= Cheers, Ian
