title: Are *.jpg.to style wildcard subdomains a burden on the DNS system?
body: <p>I noticed the service <a href="http://jpg.to/" rel="nofollow">http://jpg.to/</a> supports any word, e.g. <a href="http://car.jpg.to/" rel="nofollow">http://car.jpg.to/</a>. Curious if this kind of thing is a burden on the DNS system, due to all the names that must potentially be stored, and therefore considered poor practice. Not picking on jpg.to, but just curious because I haven't seen anyone mention the issue when it's been covered.</p>
  
  <p>Is it acceptable for a service to establish many thousands of subdomains?</p>
