IP addresses......help

Question

...I've changed my ip address a few times by unplugging my hub over night.

Just now i have visited a forum were it show you your ip address at the bottom, and when i looked at the last three digits of my ip address it looked very similar to a ip address i had before.

My question is... can your ip address return to an old ip...or do you never have the same ip twice. ty

Answer 1

You can have the same one twice.

IP addresses used by Internet Service Providers are re-used all the time. They have a lease time which expires every so often (usually 24 hours or a few days).
