First of all, virtually all IP addresses are rent – whether it is internally on your own LAN (local area network) or externally on a WAN (wide area network, including the Internet). A leased IP basically means the IP address will ‘expire’ and then the important service in charge of leasing IPs (such as your router) will either revive and reassign the exact same IP address to you personally, or you will receive a brand new IP address completely. This really is.

In the event of an Internet Service Provider (ISP), you most probably will not get the same IP address if your IP expires. The reason you will not get the same IP is because your Internet Service Provider is always renting IPs as customers connect and disconnect from their service and has a tremendous customer base.
