static IP address blog

What is a static IP address and how does it differ from a dynamic IP address?

In order for any device to communicate it needs an IP address. The type of IP address that you’ll be most familiar with is an IPv4. This is a string of numbers, usually in a format like 201.51.252.526 .

Every single device that connects to the internet needs an IP address and under the current format we’re limited to just 4.3 billion number combinations. Because of this limitation a static IP address doesn’t tend to be offered as standard and is only really available on specific, individually tailored connections.

What is a static IP address?

A static IP address is an IP that is manually configured for a certain device, rather than it being assigned to the device. The reason that it is called a static IP is because irrespective of where the device is, the IP address doesn’t change.

What is a dynamic IP address?

The majority of devices, (especially mobile) that connect to the internet will do so using a dynamic IP address. Dynamic IP’s can be reused multiple times or assigned to a large group of devices at the same time.

Why would you need a static IP and what are its advantages?
