    i-stream doesn't use DHCP. Instead the connection is session-based (IPCP using PPPoE), as for dial-up. The IP address will stay the same as long as the connection is unbroken.

    As eircom only uses routers for i-stream, the session is kept alive by the router, so in theory, if you don't power the router down, the connection will stay alive indefinitely. That's the theory though - my connection usually stays alive for a few days at a time

    DHCP is emcapsulated by IPCP. So there is a DHCP request, but it's just a bit hidden.

    If you're running the PPPoE stack on your PC, then you should be able to find out the lease time by going ipconfig /all.

    Last time I looked at an eircom connection I wasn't paying much notice, but the lease time I think is 24 hours, though this does not imply that the IP address will change after 24 hours -- the client will re-request the same IP address, and may or may not get it again from the server. Most "normal" dhcp servers will re-issue the same IP address, but eircom's may not be "normal".

    DHCP leasetimes are set on the server. You'd have to ask Eircom what they set their leasetime to on the server side.

    If you are looking to run a server, and you're worried about the IP changing, there are tons of services on the net you can use to get a static name with a dynamic IP (http://www.dyndns.org/ being an example of a free one).

    I'm open to correction on this but I belive I was told by an Istream tech that the lease is 99 Days. It was sometime ago though.
