Google Public DNS Proble - Can't find domain NXDOMAIN

[Javier Cornejo]

Hi There.
Google DNS (8.8.8.8) can't find our company domain.

Many people want to send email and google dns say domain not exist.

if we use nslookup with www.icare.cl, we don't have problem, but with
"set q=any" and try to resolv just "icare.cl" can not fin NX records.

Help me!


PS: Sorry for my bad english, I'm from Chile.

Javier, there was a brief period when all of the .cl nameservers:

$ dig +short cl. nsb.nic.cl.
c.nic.cl.
cl1.dnsnode.net.
a.nic.cl.
cl-ns.anycast.pch.net.
sns-pb.isc.org.

were reporting that icare.cl didn't exist, and Google Public DNS was
correctly passing along this information. This changed while I was
investigating your reported problem.

The .cl servers are now acknowledging the existence of icare.cl, and
MX records for icare.cl are now resolving:

;; ANSWER SECTION:
icare.cl. 86340 IN MX 15 icare.cl.s10a2.psmtp.com.
icare.cl. 86340 IN MX 20 icare.cl.s10b1.psmtp.com.
icare.cl. 86340 IN MX 25 icare.cl.s10b2.psmtp.com.
icare.cl. 86340 IN MX 10 icare.cl.s10a1.psmtp.com.

from all Google Public DNS locations.

Hope this helps. --PSRC

You don't have A record for icare.cl but you have for www.icare.cl

Note the "NOERROR" here now. This means that the name icare.cl exists,
but it has no record of the type you requested. So indeed there's no A
record. But for e-mail, all you need is an MX record:

wilmer@fiona:~$ dig mx icare.cl

; <<>> DiG 9.8.1-P1 <<>> mx icare.cl

As Paul says the name was missing entirely two days ago, but that's a
separate issue.
