IP lease query

[huggy bear]

I know that ntl don't give static IP addresses unless you have a business account (I think) but what is the story with a router that remains on all the time. Does the IP number ever change on this and if so, how? e.g does it just suddenly stop being one number then become another akin to a bloke leaping from one horse to another in a circus? (sort of thing)

My IP addy hasn't changed for a long while. Even rebooting the STB has no effect. Only leaving the STB powered down for quite a few hours would result in a possible change of IP, because the lease inthe meantime has expired. Even then you could get the same IP addy back if it has not been reallocated to someone else.

The IP addy is issued by the NTL network, to the STB or CM in your home. Only if the network is reset, is there a possibility that new IP addys will be issued as the old ones get cleared. Even then if despite the network reset, your STB/CM is still on and saying "i was allocated IP xxx", chances are the network kit will pick that up and resuse it.

Each sector of the ntl network will have been proogrammed with a range of IP addresses that it can use and issue to the kit connected into it. Who gets what IP in that range is then determined by the network's programming, usually on a first come first served basis.
