An IP.

An IP address is a number that allows you to establish a connection between two computers.

The IP address is a unique identifier for a computer connected to the Internet to identify that computer on the network. An IP address is assigned to each computer connected to the Internet and located in a domain when it is registered as an Internet resource. IP addresses are generated by computers to identify each other on a subnet. They are also used by other network devices to recognize each other's networks, allowing devices to easily connect to each other. Finding out your IP address isn't tricky; a standard IP Tracker is suitable for this, where you can also find out if your IP is clean.

The router that connects you to the Internet costs thousands of dollars, and new routers cost even more. New networks are expensive to build, so the economic incentives were strong to keep old routers working. But the Internet has changed. The network no longer works this way. Today, routers are cheap. When a new router is built, it connects you to existing networks. The router that connects you to the Internet does not bind you to it. The routers always talk to each other on the Internet, so breaking in and deleting a router isn't a big deal.

In the networking world, a default gateway is an IP address that traffic gets sent to when it’s bound for a destination outside the current network. On most home and small business networks with a single router and several connected devices, the router’s private IP address is the default gateway. All devices on your network send traffic to that IP address by default. This guide will explain how to find your router’s IP address.
