Brandon, What you don't seem to understand is that cable modem customers are connected 24x7. @Home does use DHCP, but the address almost never changes since DHCP is designed to keep assigning the same address to the same host as long as possible. Think of them as pseudo-static. If you are connected by dial-up, you only need an IP address while dialed in. With a permanent, 24x7 link, you need a permanent, 24x7 address. Even if it changes, there is always an address assigned. Being on a cable modem is effectively the same as being on a T1 (although it's a bit faster in one direction). R.
