Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a domain name that for some reason is pointing to different servers depending on where you are located in the world.

What is odd is that I have another domain that has the same DNS servers, which points to the same server regardless of your location (which is the way it's mean't to work).

Any ideas why the first domain is pointing to different IP addresses for different people?

When you say "I have a domain name" do you mean it's yours or it's simply one you are aware of? –  John Gardeniers Mar 20 '10 at 23:09

It's possible that this is a deliberate application of GeoDNS, as many companies prefer that requests from, say, the UK resolve to a host located in the UK.

If you know that this is not the case, then you'll need to troubleshoot the resolution from each location. Old, crufty resolvers with hard-coded resolution paths for some domains, etc.

If you provide the domain name in question (it's public info, after all) you'll be much more likely to get a specific, useful answer.


There is something odd going on with your DNS. The nameservers list two nameservers for your domain:

$ dig ns 172800 IN      NS 172800 IN      NS

But those two nameservers seem to be a bit... confused:

$ dig a 14400  IN      A 86400  IN      NS 86400  IN      NS

$ dig a
.                       518400  IN      NS      B.ROOT-SERVERS.NET.
.                       518400  IN      NS      C.ROOT-SERVERS.NET.
.                       518400  IN      NS      D.ROOT-SERVERS.NET.
.                       518400  IN      NS      E.ROOT-SERVERS.NET.
.                       518400  IN      NS      F.ROOT-SERVERS.NET.
.                       518400  IN      NS      G.ROOT-SERVERS.NET.
.                       518400  IN      NS      H.ROOT-SERVERS.NET.
.                       518400  IN      NS      I.ROOT-SERVERS.NET.
.                       518400  IN      NS      J.ROOT-SERVERS.NET.
.                       518400  IN      NS      K.ROOT-SERVERS.NET.
.                       518400  IN      NS      L.ROOT-SERVERS.NET.
.                       518400  IN      NS      M.ROOT-SERVERS.NET.
.                       518400  IN      NS      A.ROOT-SERVERS.NET.

The expected result from either query would have been either NXDOMAIN (if I was requesting a subdomain that didn't exist) or a series of A or CNAME records. It appears that c13 is trying to return an authoritative result and, at the same time, delegate the domain elsewhere. That could produce inconsistent results. And the c14 server appears to know nothing about your domain at all but, instead of returning NXDOMAIN it's pointing me back at the root servers. Fortunately most resolvers are smart enough to avoid going into a loop at this point.

I don't see anything that would indicate why you might get different IPs back when resolving from different parts of the world, but I could certainly see why this domain might behave inconsistently. You can probably fix the c13 results (eliminating the delegation) by editing your DNS config in whatever control panel they provide. You'll need to talk to your hosting provider's support department about figuring out if you need to change your NS records at your registrar to point to something other than c14 or if they just need to fix c14 so it has a valid answer for your domain.

The domain is my own and I didn't want it to do this. Its –  David Mar 22 '10 at 10:12
