evelmunkey said:Most cable companies assign a 24 hour lease to your ip address and is renewed only if your cable modem is connected when the lease expires. So if you left the modem off for more than their lease (24 hrs), you would change your IP address when the modem is restarted. I am not sure if all companies work this way but the three I have been with have always done it and the lease time is always 24 hrs.
The leases are usually far less, but it all depends on how the DHCP servers are configured.
Generally unplugging your modem for 5 minutes will give you a new IP
