well, there is also the fact that all the dynamic IP schemes for DSL suck. most providers these days are offering PPPoE which is a lot like a dialup connection in terms of the ISP's level of control over the connection (it is a session based connectivity protocol, i.e. your DSL has to "dial up" with a username and password). DHCP is not so bad, unless your DSL network is overbooked, in which case you can have problems renewing leases (read: you can't access the Internet because your ISP takes away your IP address and won't return it or give you a new one). to me, avoiding all of that hassle is worth a few extra bucks a month. my static IP DSL is rock solid.
