For instance, if “Bob” walks into work in the morning and starts up his computer, and the DHCP server assigns his computer a dynamic IP address, a DNS entry “bob.example.com” can be associated with that IP address. Even though Bob’s IP address may change every time he starts up his computer, his DNS name remains the same. This lets users communicate with Bob’s computer without knowing the IP address.

You can also use dynamic DNS to provide static host names for users who connect to the Internet through a modem. An ISP can set up dynamic DNS so a home computer has the same host name every time it connects.
