View Full Version : Perplexing DNS problem
02-03-2006, 07:16 AM
Can someone help me out with this. I'm getting a little desperate:
Basically I can ping IP numbers but not domains, so I have a DNS issue, but my Networks Settings are correct and match all the other machines in the office (apart from own IP of course) which are fine.
I've tried creating a new Network Location and I've tried flushing the cache (i.e. lookupd -flushcache ).

Yay... you're resolving (almost).
try setting your DNS server in System Preferences to
It is a DNS server that I administer. (Please note this is not the same as the last address)
After setting it as the DNS server, try
You should get results (hopefully)

That's it. Thanks a million.
What I don't get is why the dozen or so other machines in my office work fine with our ISPs DNS servers when this one won't?

I don't know...
That said, would you mind sending me a PM with the name of your ISP so I can try to find one of their DNS servers that will work for you? The server you are using now is a PC located the basement of a house in Redmond, WA, USA.

Haha, no problem. Thanks again for your help.

That's one , um. "interesting" ISP you have there.
Their name servers don't respond.
Their registrants main name servers respond without resolving addresses.
Fortunately, their registrants oddly named "extra" name servers do.
Get a clue, people.(ISP)

Ok, so your ISP is being very mean...
go ahead and use
ns1.nz.opennic.glue (Auckland, NZ) - 22.214.171.124
It works, it's close to you, and I tested it fully
