Re:What about WAP enabled devices (Score 1)

Because of the way they work...

Phone -> Gateway -> Wapsite

...with most providers using their own gateway, generally the phones are allocated IP's in the private address space.

This does make some sense, since a random probe (you know, you get them all the time on any machine that's been connected for longer than 10 minutes) could upset this little (generally buggy) device. An nmap scan is enough to crash some of the early 7110's (which btw have had a lot of stack problems so don't be suprised about different ping replies between different firmware versions). Even with the always-on GPRS, it's likely some kind of cut-down and reshaped DHCP will be used, since even though the phones can stay on-line all the time a lot of people don't leave them switched on all the time... :) silly really, I have about 3 weeks uptime on my Motorola Timeport :)
