Check DNS Servers – Nslookup

Shifting to the new server, I had some problems with the domain redirections. For some weeks the domain pointed sometimes still to the old server. My domain provider could not see a mistake in their settings, first. Nevertheless, I wanted to work on PhYnformatik, what, due to some links, is only possible using the domain, not the ip. Therefore I needed a DNS-Server pointing to the correct sever.

But how do I know, where the DNS-Server is pointing?

The command line program Nslookup does the job. To see where the current used server is redirecting you for phynformatik.de, use:

$ nslookup phynformatik.de

To see what another server (here the Google server) is telling you, use:

$ nslookup phynformatik.de 8.8.8.8

By the way, the problem was an old CName record still pointing to the old server.
