Not every cable internet provider does things that way. You probably have @Home, right? They do that, but two other cable internet providers I've dealt with just give you and IP number, and some name that corresponds to that number (and hence always changes when the number does). Several people have recommended various "dynamic DNS" services. I use dyndns.org and it works beautifully. Basically, you sign up for a hostname of the form <your-choice>.dyndns.org (there are a few other choices for the suffix). You then run a client program (they have them for most operating systems) which detects your IP number and sends it to dyndns.org's DNS server, which updates its table to reflect your current IP number. The client programs I have even work through a "cable/dsl router" -- that is, my PC running the dyndns client has a 192.x.y.z number on the local network, but the router's "outside" IP number is what gets passed to the DNS server. I don't know how that happens, but it works perfectly (surprisingly!) -- it even worked automagically when I switched from having the PC plugged directly into the cable modem to having the router in between. --Robert --------------------------------------------------------------------- To unsubscribe, mail [EMAIL PROTECTED] with the line: 'unsubscribe vnc-list' in the message BODY See also: http://www.uk.research.att.com/vnc/intouch.html ---------------------------------------------------------------------
