Dynamic Internet Protocol Address (Dynamic IP Address)

A temporary Internet Protocol address assigned to your computer hardware at the start of your High-Speed Internet session.

The dynamic IP address is engineered specially for high-speed transmissions and is assigned from a pool of addresses owned by one's own Internet Service Provider. This address remains the same throughout your Internet session. When you disconnect, it is returned to the pool for assignment to another customer. When you reconnect to the Internet, you are again assigned a dynamic IP address. Dynamic IP addresses from the pool are assigned to just one customer at any one time, ensuring the uniqueness of the address on the Internet.
