Penteract NAT Detector

Detect whether your ISP put you behind a NAT (Also called a CGN - Carrier-Grade NAT) and therefore you're sharing a public IP address with other subscribers. This might cause you some trouble such as if someone else sharing your public IP address misuses a search engine and that search engine blocks or rate-limits your IP address. This app shows you the steps from your computer to a public IPv4 address.
