Public vs. Private IP addresses
As you might have noticed, we are talking a lot about public and private IP-addresses, but what are they, and what is the difference between them?

You have searched for 20.20.20.0, which is a public IP address and most likely related to your own router as its external IP. It is a combination of four numbers, called octets, which are separated by dots. And because your router acts as a bridge between your local network and the internet, it also has another IP called a private IP address. The public IP address is assigned by your ISP, and is pretty much outside of your control.

The private IP address is built up in the same manner, also consisting out of four numbers separated by dots, but cannot be the same as the ones used for a public address. It is used to connect your computer to the internal network and whenever you visit a website or send out an e-mail, your router will receive it through your private network and send the information out though your public interface.

Another difference is that public IP addresses given out by providers are likely to change as every router in the world needs a unique public IP address, basically just like people and their home address, so ISPs tend to use dynamic IP addresses to make sure they don’t need more than necessary because of the finite amount of available addresses. They do this on a per-request basis. When you disconnect your router from the internet, the ip address is revoked and given to the next user that connects.

It is also common to have a static public IP address, which doesn’t change regularly like a dynamic one does. Nowadays, this is almost strictly prohibited to servers that serve websites and e-mail and are based in datacenters around the world and are often referred to as ‘the cloud’. This makes sense, as these servers need to be available 24/7.

The biggest downside of a public IP address is that it is outside-facing and can reveal details like a rough estimate of the users' location, as you can also see on this website. Using a VPN, like we offer in our ‘Hide my IP’ service, can give you some peace of mind if you don’t like the idea of being ‘out in the open’ when browsing the internet. Because it is another layer on top of your network, it hides your public IP address from the internet as it gives you a randomized address. It’s even possible to completely obscure your physical location.
These days you can buy routers which have this option built-in, but the most common way of doing this, is by installing an app on your computer or phone.
