What is a router?
A router is a piece of hardware that directs traffic between networks, most commonly between a computer and the rest of the internet. Practically, the word “router” is often used as shorthand for “wireless router”, a type of router that also functions as a wireless access point.
How does a router work?
Routers use the DHCP protocol (see DHCP) to assign IP addresses to each of the devices on their network. They typically directly on the device’s firmware and don’t employ software. The most popular router firmwares are DD-WRT and Tomato.
ExpressVPN users can set up their VPN connection directly on a router’s firmware, which allows every device connected to automatically route their internet traffic through the VPN server.
