I changed my domain's nameservers, but I don't think the change was processed correctly. Can anyone help me understand the result below "AFTER"? In my registrant's control panel, I change the name servers from ns1.secure.net (etc.) to ns1.linode.com (etc.). But, after the changed, it looked like the DNS was pointed nowhere at all.

Is this a normal in-between state during the process of nameserver changeover, or does this mean that the new nameservers were not correctly assigned?

(For the time being, I have changed the nameservers back to ns1.secure.net, so if you run dig yourself now, you'll see "BEFORE".)

More detail about how I got here:

  • A previous developer registered the domain with MelbourneIT.
  • I transferred the registration to active-domain. The DNS settings carried over.
  • Having trouble getting the www subdomain to work with the nameservrs, I tried to point the nameservers to Linode.
  • The site "went down" and, as you can see, the DNS pointed nowhere.

It appears that you did not get an answer because the DNS server your client computer is pointed to is not the authority. The require authority flag (if I remember the name right) is likely set and the request not completed because the DNS you queried was not the authority. This can be common if you are pointed to a Bind instance. By default, recursive look-up is not set and/or try a query directly is not set in Bind. I went through this recently, but forgive me if the exact setting names and flag names are not exactly right because I am going off of my memory.

Try: dig @ns1.linode.com mobtownballroom.com any

Alternatively, try: dig +trace mobtownballroom.com any

These should give you an answer. The first one you are querying the authoritative name server directly. If this does not work, the next will do a trace and find the authority.

OK, this helps. I'm not sure I have enough access through the dinky "control panel" offered by my domain registrant to follow your advice, but I will see if they can help me given this information. Thanks. –  Dan Allan Apr 5 at 20:35
    
Dig is available via Linux of course. But it can be available on Windows too. I have not done this. I use Linux. However, here is a link that may help: nil.uniza.sk/windows/windows-7/… –  closetnoc Apr 5 at 20:39
    
I'm on Linux; dig is fine. I meant the tools to change the "require authority" flag or whatever its proper name is. –  Dan Allan Apr 5 at 20:44
    
For the two commands I gave, you will not need that. The require authority comes from Dig. The other two are settings in Bind itself. –  closetnoc Apr 5 at 20:46
    
In fact, while I was thinking about it, I was not suggesting changing any settings. I was just explaining what I found and how to get around it. If you can change the settings, then that would help for the future. –  closetnoc Apr 5 at 20:50
