The modern internet can be thought of as akin to a very complex, and very fast, kind of messaging system. But no messaging system can function without a way of distinguishing one recipient from another. This is where the Transmission Control Protocol/Internet Control Protocol (that’s TCP/IP) comes in. It works by assigning every device on a network a unique address. These addresses are known as IP addresses.
What Are Static and Dynamic IP Addresses?
There are two main types of IP addresses: static ones, and dynamic ones. As the name might suggest, the former remain fixed, while the latter are assigned automatically.
It’s possible to configure a network, or device, to use either. But in most UK homes, dynamic IPs are the default, while static addresses are reserved for particular devices, like the router. So, a new device might connect to the network, and be assigned an address via what’s known as the Dynamic Host Configuration Protocol server.
How Dynamic IP Addresses Change (and Why They Do)
Dynamic IP addresses change every time a new device connects to the network. You can think of it like checking into a hotel. You don’t have the same room assigned every time you visit, and this allows the hotel to effectively manage capacity.
Dynamic addresses are more difficult to track, which makes them inherently more secure. They’re also more user-friendly and flexible. When the address isn’t being chosen by the user, there’s no risk of one device conflicting with another.
When and Why Static IP Addresses Stay the Same
For all of the advantages of a dynamic address, it’s fair to say that static ones haven’t gone anywhere. This is because they tend to offer advantages of their own. They tend to offer a simpler, more robust connection that makes them perfect for servers and business applications that are going to be used constantly, and that need special priority on the network.
If you want to set a static IP up at home, then you might need to overcome additional hurdles. You might even find that you’re unable to assign static IPs to your devices without paying extra.
If you want to learn how to change IP address yourself, then there are a number of online guides to consider.
Choosing the Right Option for Your Needs
For most home users, the flexibility and efficiency of a dynamic IP address makes it the go-to choice. If you’re doing something a little more elaborate, like hosting a website, or running an on-site storage server, then having a static address might be preferable. It can be a worthwhile exercise to try both, so you can understand exactly how they work, and which best fits your purposes.
