Unless they're doing something stupid, your web requests are still made of the original IPs, just the results are cached. I have the same thing, here, on my LAN. A Squid proxy server, so that if I have guests doing the "look at this" thing amongst themselves, or a bunch of Windows PCs doing updates, everyone after the first query sees the cached version. You can try it out, and see. Find a public DNS server that you can access on a different-than-usual port. Make a rule on your gateway that connection attempts to your router IP and DNS port get redirected to the external DNS server on the unusual port. It's probably possible to make an outgoing redirection rule on the PC that your testing, itself. As far as them optimising things, with satellite internet, there's a prolonged propagation delay. So them doing local caching means that you get to see cached data on this side of the satellite, rather than have to wait for it to come through it. Years ago I used an ISP that did that sort of thing, their service was dreadful. Everything was late, worse than dial-up. Their crap performance was the thing that pushed me into running my own DNS servers. Their DNS servers were even worse than their everything else that they did. Frequently, it could take half a minute for it to return a result. When you consider that way too many pages are a construct of data from here, there, and everywhere, not just the sites own service, it could take an age to load a page. Any service that mucks you about, and fobs you off, and leaves you trying to resolve a problem for days on end, doesn't deserve your custom. Especially if the problem is theirs. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
