DNS settings in Aegir I successfully set up Aegir hosting in my Ubuntu based VM. At the time of new site creation I face some problems. I got message saying the new site successfully installed but when i click "Log into site" I get a "page not found error". I understand there will be DNS issue, how can I resolve this?

While trying same thing in my local pc. I get to the new site by modifiying my hosts file.  Is it possible to get the site without altering my hosts file?
Check out item 2 on this page on setting up sites in Aegir.


  Login to your DNS control panel at your domain registrar, or wherever
  your nameservers are, and setup the DNS for the domain name to point
  at your Aegir server. It's worth including a wildcard record - ie an
  'A' record for '*' to resolve to your aegir server - then you can
  easily setup new sites on subdomains without having to ever setup DNS
  again!


This video also looks pretty neat, not sure how much it'll help though.
