This is a business decision taken by many ISPs - in fact, many ISPs who use dynamic addressing are starting to deliberately lower lease times for dynamic IPs (1-3 days seem to be common these days, 1-3 hours does seem on the short side), and implement mechanisms in their back-end systems to be sure the user will NOT be able to renew a lease for the same IP, but rather always be given a new one after this 1-3 day period expires. This way, you force any users who require permanent addressing (typically users who wish to run servers on their home connections) to buy your "premium" service rather than your $29.99/month-for-2Mbps low-end product. After all, you don't want your $29.99/mo users to actually USE 2Mbps, since then you will be selling your product with a loss (yes. really.), so you force the users most likely to actually use your bandwidth, to pay more for it. If you happen to be the incumbent or through other means have near-monopoly in the local market, this becomes even more attractive, as you don't need to worry that much about users switching providers rather than upgrading to your premium product. /leg -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
