(Useful) DNS servers

June 04th 2007 Posted to Geekery

Here’s a list of useful dns servers:

New SAIX DNS’s are as follows:

196.43.34.190
196.43.46.190

Hetzner’s DNS servers

196.7.147.235
196.7.150.34

A useful IP to remember is:

198.6.1.1

It’s an open recursive name server for all to use, regardless of your service provider. Always up, always accessible, always works :) (Thanks, Carl)

To check a dns server for a specific address:
dig @198.6.1.1 macgeek.co.za

That’s how, a few weeks ago, I found out that any mail sent via mail.tomorrowtoday.biz (a Hetzner server) was being routed to their old servers, instead of being pointed to the new servers (I’d transferred the hosting of a few domains to Media Temple). Of course, the mail wasn’t being bounced and it wasn’t being delivered (to where it should be).

dig @196.7.147.235 tomorrowleaders.biz

revealed that Hetzner hadn’t removed their dns zones for the applicable servers. A request to them to do this worked, an elicited an apology – but didn’t do much to placate angry clients. *sigh*
