When you use +trace, you(the dig utility actually) are searching all the way from root servers until sipxecs.sipfoundry.org. Remember that DNS work like an inverted tree[1].
The root servers know who has the authority on org. domains, which in turn know the authority for sipfoundry.org. and finally the host sipxecs.sipfoundry.org. When you just ask dig to search for the host sipxecs.sipfoundry.org., it will ask your DNS server that will do the whole job, if it has no info about that host or simply answer with the cached info - that was what you get. In your case, your DNS server(172.23.12.222) already had the info about sipxecs.sipfoundry.org. and it will expire in 28395 seconds. ;; ANSWER SECTION: sipxecs.sipfoundry.org. 28395 IN A 216.142.118.34 If you runs that server you can always flush its cache in order to get the fresh info. - MM [1] http://en.wikipedia.org/wiki/Domain_Name_System On Wed, Apr 29, 2009 at 2:24 AM, Nikolay Kondratyev <[email protected]> wrote: > I also can not access http://sipxecs.sipfoundry.org... > I'm not sure what is happening, but > dig +trace sipxecs.sipfoundry.org shows the new address, while > dig sipxecs.sipfoundry.org (without "+trace") shows different (old?) > address... > > [r...@sipx3 yum.repos.d]# dig +trace sipxecs.sipfoundry.org > > ; <<>> DiG 9.3.4-P1 <<>> +trace sipxecs.sipfoundry.org > ;; global options: printcmd > . 202693 IN NS A.ROOT-SERVERS.NET. > . 202693 IN NS B.ROOT-SERVERS.NET. > . 202693 IN NS C.ROOT-SERVERS.NET. > . 202693 IN NS D.ROOT-SERVERS.NET. > . 202693 IN NS E.ROOT-SERVERS.NET. > . 202693 IN NS F.ROOT-SERVERS.NET. > . 202693 IN NS G.ROOT-SERVERS.NET. > . 202693 IN NS H.ROOT-SERVERS.NET. > . 202693 IN NS I.ROOT-SERVERS.NET. > . 202693 IN NS J.ROOT-SERVERS.NET. > . 202693 IN NS K.ROOT-SERVERS.NET. > . 202693 IN NS L.ROOT-SERVERS.NET. > . 202693 IN NS M.ROOT-SERVERS.NET. > ;; Received 488 bytes from 172.23.12.222#53(172.23.12.222) in 0 ms > > org. 172800 IN NS D0.ORG.AFILIAS-NST.org. > org. 172800 IN NS C0.ORG.AFILIAS-NST.INFO. > org. 172800 IN NS B0.ORG.AFILIAS-NST.org. > org. 172800 IN NS B2.ORG.AFILIAS-NST.org. > org. 172800 IN NS A2.ORG.AFILIAS-NST.INFO. > org. 172800 IN NS A0.ORG.AFILIAS-NST.INFO. > ;; Received 442 bytes from 198.41.0.4#53(A.ROOT-SERVERS.NET) in 209 ms > > sipfoundry.org. 86400 IN NS lambda.sipfoundry.org. > sipfoundry.org. 86400 IN NS dns.nostrum.com. > sipfoundry.org. 86400 IN NS dns.byexample.org. > ;; Received 150 bytes from 199.19.57.1#53(D0.ORG.AFILIAS-NST.org) in 64 ms > > sipxecs.sipfoundry.org. 3600 IN A 67.221.235.27 > sipfoundry.org. 3600 IN NS lambda.sipfoundry.org. > sipfoundry.org. 3600 IN NS dns.nostrum.com. > sipfoundry.org. 3600 IN NS dns.byexample.org. > ;; Received 150 bytes from 72.232.205.74#53(lambda.sipfoundry.org) in 169 > ms > > [r...@sipx3 yum.repos.d]# dig sipxecs.sipfoundry.org > > ; <<>> DiG 9.3.4-P1 <<>> sipxecs.sipfoundry.org > ;; global options: printcmd > ;; Got answer: > ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 8371 > ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 3, ADDITIONAL: 3 > > ;; QUESTION SECTION: > ;sipxecs.sipfoundry.org.
