Router Checker is a free, web-based tool that checks your router’s settings and detects if it may have been hijacked by cyber criminals. If your router is compromised, every single device on your network is at risk of being hacked. The Domain Name System (DNS) is like the Internet’s phone book. DNS servers translate the names of websites into the phone numbers (IP addresses) that computers need to talk to each other.
Good servers translate the names of websites into the IP addresses you’re looking for. Bad servers (often called rogue DNS servers) translate these names differently to reroute your web traffic. Using a rogue DNS server is like using a phone book that someone’s forged to help them scam innocent people.
