DNS wildcard

[skotman]

I have a customer who is going to want multiple domain names, added at random (besides the

http://www and

mail). I did some research and found that DNS has a wild card so you can have *.domain.com. I've got it working but I'm curious to know what others think. Is this a good idea? What problems can this cause?
Thanks!

I assume you mean sub-domains, ie. new.domain.com, old.domain.com, another.domain.com. Works well with the wildcard entry in the dns. You could make separate entries, but no need if your sending everything to one IP address. If at some point you decide to forward a specific sub-domain to another IP address, you'll need to make separate entries for each on in your dns.

SO if in the future I want abc.domain.com to go to some other IP address then where the wildcard goes I just need to specifiy that?

I'm not sure if you can have a wildcard entry and a regular sub-domain entry for the same TLD. But yes if you wanted abc.domain.com to go to another IP you would specify that in your dns. You may have to remove the wildcard and create separate entries for your other sub-domains to make it work though.

I just tested it. It looks like it checks to see if the subdomain has a real record and if it does it uses that IP, other wise it uses the wild card. I think this is how Network Solutions is doing the contreversial domain redirect.
