This is the following information we know about your current networks public IP. You can hide your ip address and location by using a VPN service to block unwanted spying and surf the web and download stuff without having to worry about who sees what you do. For you internal network, we will need to probe the network for a short while to see which one your router responds on.

Click the button to proceed. There is still a simple way to quickly find out your routers IP address. Simply try any of the following links and see if the routers web-interface pages show up: List of the most common IP addresses, admin usernames and passwords for the major router brands out there. The default gateway, also commonly the routers internal IP address, is what your home devices, such as PCs, laptops, tablets and phones, will use when requesting pages and content on the web.

Since many computers and devices can be connected to the internet through a modem at home, and there is a limited number of IPV4 addresses in the world, the modem or router will translate and route all the packets to the correct place. In practice this means that from an outside observer, every device from your network will share the same IP address, while inside the home network they will have different local IP addresses. Apart from having a Public IP address, your router or modem also has a private IP, or internal IP that is used to communicate with devices in the local network.

The modem or router will usually assign itself at the first IP in the subnet, something like The IPv4 address is of limited size, so there can only be a certain number of addresses in the whole world. Although this number is quite huge, increasing demand for new IP addresses resulting from the rapid growth of the internet is creating a shortage for it.

One of the main features of this version is the vastly high number of addresses it can support compared to the traditional IPV4.

If you have a dynamic IP address plan, simply disconnecting and reconnecting your router would provide you with a fresh address, since you will acquire a new address every time your router connects to the ISP. This is not always the case as some ISPs will sometimes give the same address when reconnecting.

Your IP address is your identity on the web. It is possible to trace your internet activity with it, although this requires access to the server logs of websites.

Usually this is handled automatically by your router so you don't need to do anything. However, you need to know the router's address if you want to configure it from the web interface.
