DNS & httpd.conf

Hi,

I have a dedicated server, and looking to change the DNS of about 300+ domain names to implement the wildcards. I can do it one by one by logging into WHM, but it is too much time consuming.

Secondly, out of these 300+ domains, only one is the main site and others are parked and pointed to that main site. Now, my httpd.conf has about 300 entries of these domains. Will it slow down the server? If yes, is there anyway to overcome this situation.

Looking for your advice.
