DNS Question? Not to do with being down either

[el2ik]

Hey,

On my site http://www.novetec.org some people are reporting a DNS error, i know about the whole ISP delivering thing but it's not that as this site is not on Powweb and on a server that hasn't been affected in over 2 years....

Anyways...

My friend suggests that I change the CNAME in the DNS, can someone explain this to me? Thanks a bunch

Some times you need a host to respond to more than one name.

eg webpc.wanbridge.net could be a server that does a number of things, including acting as the web, mail,wins servers all in one

Now you can point an ip address say 65.50.60.3 to www.wanbridge.net and you may also want this to point to ftp.wanbridge.net

you do this with a CNAME record in the DNS database, also known as aliases ,so the record could be

www Alias webpc.wanbridge.net

ftp Alias webpc.wanbridge.net

here we have created a CNAME within a domain wanbridge.net, the CNAME is set to end with the domain name

if the machine that this is being pointed to is not in the domain name then it wil need an A record in the DNS database

or if using a GUI like windows 2000 you can enter the fully qualified domain name for the host eg. ftp and FQDN www.anotherdomain.com

OK all this may have your throughly lost unless you know about DNS it is best to leave well alone and get a network administartor to change things, although DNS is not that complicated you need a sound understing of how it all works otherwise? well i refer the honorable gentleman to the case of powweb dns v angry users
