IP addresses
Does anyone understand how IP addresses work? Please excuse my stupidity and help me understand!
As most of you know, I'm currently a finalist in a contest (see 'I'm a Finalist' thread if you have no idea what I'm talking about). There was a problem in their system so now they're limiting votes to 1 per IP address and they're going to eliminate multiple votes from an IP address.
I know when you reconnect to the internet you get a new IP address, but how many IP addresses would an internet service have? Are they indefinite or will they just rotate and run out?
If my neighbor uses the same internet service I do, could they potentially get the same IP address as me when they connect at some point?
Where my husband works they have thousands of computers but they're all on 1 IP address? How does that work?
Thanks for listening to my million questions!!
