Frequently asked questions

An IP address is the number your network uses to send and receive data on the internet. The address shown at the top of this page is your public IP — the one websites and online services see when you connect to them. It is assigned by your internet provider, not chosen by you, and it can change over time.

A public IP address is visible on the open internet and is shared by every device behind your router. A private IP address is used only inside your own network — for example between your laptop, phone and printer at home. Private addresses fall in reserved ranges such as 10.x.x.x, 172.16–31.x.x and 192.168.x.x, and they are not reachable directly from outside your network.

IPv4 is the older format, written as four numbers separated by dots (for example 203.0.113.42). Because the supply of IPv4 addresses is limited, IPv6 was introduced — a longer format written as groups of hexadecimal digits separated by colons. The two formats run side by side; your connection may have one or both, which is why the panel above can show a value for one and “Not detected” for the other.

Your IP address is what lets data find its way back to you, so it is fundamental to everything you do online. It also carries some rough information — such as the region and internet provider associated with the connection — which is used for things like content localisation and basic fraud checks. It does not reveal your name or exact street address on its own.

The simplest way is to open this page — your public IP address is detected and displayed automatically at the top. To look up a different address or a domain name instead, type it into the search box in the hero section and the results will appear below.

A dynamic IP address is assigned by your provider from a pool and may change periodically — this is the default for most home connections. A static IP address stays the same over time and is usually requested by businesses that host servers or need a fixed address for remote access. Both work the same way day to day; the difference is only whether the address is expected to change.
