This article will explain IP address changes and which locations have the same IP address.
Once you connect to a location, you will have the same IP until you reconnect. That is done with the "Round Robin" principle when a new user connects to one of the available servers in random order.
If you wish to have an identical IP each time you connect, you can try connecting to the Static IP locations. These locations always have a single IP address shared among all users currently connected to that specific location.
