Should I block HughesNet satellite provider?
SwellJoe: Why are you asking us?Contact Hughes network administrator.  They probably have a prefetching web caching server, that may be misconfigured or have a bug when interacting with your particular web server with your particular configuration...or your site may have some cache-control data botched.  Or a little of both.You have the offending IP addresses...look them up at ARIN.net, and find out who is responsible for their network.  Send them an email with what you've just told us.
