1.1.1.1 not showing correct data for bsrgroup.com.au (8.8.8.8 and 1.0.0.1 are fine)


#1

1.1.1.1 doesn’t have the correct data for this domain (and possibly others, but this is the one we’ve discovered so far), but 1.0.0.1 DOES, as does google’s 8.8.8.8

i.e.:

bsrgroup.com.au
Server: 1.1.1.1
Address: 1.1.1.1#53

UPDATE:: I can’t post replies to this message for some reason, I think because my account is new and still awaiting moderation.

However, this problem seems to have been resolved. NOW when I run an nslookup against 1.1.1.1 for bsrgroup.com.au it returns the correct information:

bsrgroup.com.au
Server: 1.1.1.1
Address: 1.1.1.1#53

Non-authoritative answer:
bsrgroup.com.au mail exchanger = 10 au-smtp-inbound-1.mimecast.com.
bsrgroup.com.au mail exchanger = 10 au-smtp-inbound-2.mimecast.com.

However, it was broken for at least several days and perhaps weeks (meaning that e-mail sent by anyone using 1.1.1.1 as their resolver to that domain wasn’t delivered, because it couldn’t find an MX record). I don’t know what fixed it today, whether it was my post here, or something coincidental.

It works fine for me

nslookup bsrgroup.com.au 1.1.1.1
Server:  1dot1dot1dot1.cloudflare-dns.com
Address:  1.1.1.1

Pretty weird for 1.1.1.1 to return a referral. It sounds like “1.1.1.1” is being intercepted by a different server, or there’s a weird bug.

Can you post the diagnostic information?

bsrgroup.com.au
