Dynamic IP address assignment means that your IP address is assigned to you only temporarily and may be changed by your ISP. This makes it more difficult to ensure continuity of service to your network. Consider again our telephone number analogy. When your telephone number changes, you are able to place outgoing calls. However, until your new phone number is registered with Directory Services, other people are unable to look up your new number and place calls to you. Similarly, whenever your IP address changes, a record associating your server with its new IP address must be published with the equivalent of Directory Services (known as Domain Name Service or DNS) before incoming traffic can find you.

If your IP address is dynamically assigned and you have a dedicated connection to your ISP (for example, with a typical cablemodem), you may find it helpful to use a dynamic DNS service . We strongly recommend you review Appendix B: Dynamic DNS services for more information about this worthwhile option.
