I don't want to use that link unless I have to" Simplest solution to this is: don't advertise the path in your map entry. # However, if someone wants to cost this particular site a lot of money, they # could hand-route a whole pile of large mail directly to UUNET. If they knew about the unadvertised link, and if they had dark intentions. If and when this ever happened, I think an active response is better than the passive response of rerouting. Active in what way? Yelling, screaming, complaining, pulling links, public flamage, etc. This assumes that sending the person private e-mail doesn't work. It gets pretty far fetched, but even this contrived example doesn't make a case for limited rerouting. I rerouted "decwrl!ucbvax!foobar.berkeley.edu!user" into the more direct "user@foobar.berkeley.edu" because ucbvax is a Vax 750 and it can route packets more easily than it can route mail messages. I didn't want to advertise decwrl as a domain server to the .berkeley.edu domain, but in fact _any_ directly connected Internet host could be considered such since Berkeley allows external IP traffic to all machines on its internal net. _That_ is an example of limited rerouting to address a specific need. It wasn't a single individual, noone had any dark intentions, and noone came up with a way to tell the world that "decwrl!foobar.berkeley.edu!user" would work without bogusly registering "decwrl .berkeley.edu". -- Paul Vixie Work: vixie@decwrl.dec.com decwrl!vixie +1 415 853 6600 Play: paul@vixie.sf.ca.us vixie!paul +1 415 864 7013
