I have a centos box from linode and I have set the
/etc/resolv.conf to only one domain.
Is it okay to host multiple domains on the same machine, while only one domain is configured with the above?
For example if I have
hostname.mydomain.com as the main domain, and have a few vhosts under apache
somedomain42.com is this still a correct setup?
Also I found
http://freedns.afraid.org/. Should I use it for my domain? Is it good to use an external DNS instead of my registrars DNS?
