[squid-users] No DNS records

Hi all...

Most sites I can get without problems, but with some URLs I get always this
message and with some URLs I get it only sometimes. I hope someone can help
me. THX.
Here is the error message:

The requested URL could not be retrieved

----------------------------------------------------------------------------

----
While trying to retrieve the URL: http://www.squid-cache.org/
The following error was encountered:
Unable to determine IP address from host name for www.squid-cache.org
The dnsserver returned:
No DNS records
This means that:
 The cache was not able to resolve the hostname presented in the URL.
 Check if the address is correct.
Your cache administrator is rollolo@web.de.
