A router is a device that connects your computer to the internet and allows you to share files, printers, and other devices on your network with others in your home or office. A router also provides security for your data by filtering out unwanted traffic from the outside world. Routers are typically connected directly to your modem or cable/DSL box.

Dynamic DNS-  lets you automatically update the domain name servers on your router when your external IP changes, making it easier to find your router online.

Parental Control – This enables parents to control what their children do online. Some routers offer parental controls that let you block websites based on categories like gambling etc.

QoS – Improves the performance of streaming video and audio applications. It lets you prioritize bandwidth for important tasks like downloading large files or playing games.

VPN – Creates a secure tunnel between two locations. Using a VPN, you can securely access resources on the web while remaining anonymous.

Routers connect computers to the Internet, allowing them to communicate with each other over the local area network (LAN). They can be used to provide wireless access points for wireless networks. Routers can also be used to create virtual private networks (VPNs) so that multiple users can have secure connections to the Internet through one public IP address.
