Demon have spent a great deal of time and energy developing a system which allows customers (who have individual IP addresses) to dial in to any one of a number of PoPs and have their mail etc automatically routed to them; the IP number is dynamically bound to the particular modem they are coming in on at run time. They are justifiably proud of this system. I believe that someone from Demon has also pointed out that it is much more efficient that the usual "class C per customer" approach, which assigns 256 addresses to half a dozen machines. We strongly encourage our customers, most of whom are providers, to use dynamic routing for dial up, but we can understand Demon's situation ... and find it hard to condemn them when there are so many more glaring examples of waste of IP address space. -- Jim Dixon VBCnet GB Ltd +44 117 929 1316 fax +44 117 927 2015 VBCnet West +1 408 971 2682 fax +1 408 971 2684
