Yes.  As the docs in the "see also" section of the VirtualHost directive
docs say, you should be using the IP address or "*" to match all IP
addresses.

If you put in a hostname, apache simply looks up the ip address
corresponding to that hostname and uses that.  This leads to unnecessary
DNS dependencies.  See:
http://httpd.apache.org/docs-2.0/dns-caveats.html
