What is an IP address?

To make it possible for computers to find and identify each other they need their own number. An IP address, short for Internet Protocol address, is a number that makes the computer visible to all other computers on the Internet. This is similar to how phones find each other by using a phone number. An IP address is usually associated with a company or agency. For home networks, this means that it identifies their Internet service provider.

The Internet Protocol address is important to know to see if your modem is already working with a modern IPv6 address or the older IPv4 address. In addition, it can be important if you want to share services on the Internet yourself. The address must also be known for security techniques such as IP whitelisting: only allowing certain Internet Protocol addresses to appear on, for example, a login screen.

Is my Internet Protocol address dynamic?

You can check this too. If you come back to this website in a few days, your IP address may be different. If you are looking at the website from the same device at that time, it is probably dynamic: it changes regularly. This is good to know because it helps protect your privacy.

Usually, Internet Protocol addresses of business connections are fixed. This has to do with IP-whitelisting. IP-whitelisting is not possible with a dynamic address. Private homes often have dynamic addresses. In the Netherlands and Belgium, the address will often only change when the modem is turned off and on, or when you switch internet providers.
