There's an Akamai across the hall from my office, and the way it was
explained to *me* was that the DNS always returns the same IP address
for a given Akamai'zed page (so the URLs in the HTML are consistent),
but routing games are used to direct the packets to the appropriate
server. In other words, it's one IP that points to disparate machines.
