What is a “dynamic” IP address?
An IP address is your computer’s address for the Internet. When you visit a web
page, you are asking the page to send information (the text and illustrations on
the web page) to your computer. The web page sends this information to your
IP address.
An IP address is a series of four numbers separated by periods, with each
number having a value from “0” to “255.” So, for example, “10.100.1.253” could
be an IP address.
There are two general types of IP addresses: static and dynamic. A static IP
address is always the same. A dynamic IP address can change every time you
connect to the Internet.
How to determine if you have a dynamic IP address
When you signed up with your ISP, they provided information about your
connection to them. If this information included a statement such as “IP ad-
dresses are assigned dynamically,” you have a dynamic IP address. They may
also have used the phrase “DHCP,” which also indicates you have a dynamic IP
address.
If, however, they provided a specific IP address, then you have a static IP ad-
dress (and you should skip the rest of this chapter and go to the next chapter).
