Generally the CDN provider would have a cluster of machines/IP's on each of
their locations that are reused by different customers and are probably
divided by service/content. They would probably be stable but can vary due
to service improvements or disruptions. As it was noted Akamai is putting
servers into the ISP's, I don't think that others like L3 or Limelight do
it (or seen evidence that they do).
