ipchecker.net is a reference site for the numbers behind your internet connection: IP addresses, router logins, DNS servers, ports and the tools to check them.
What this site is for
Most people meet these topics only when something breaks. The Wi-Fi is connected but nothing loads, a game needs a port opened, a router password has been forgotten, a website shows DNS_PROBE_FINISHED_NXDOMAIN. The answers exist, but they are scattered across forum threads, manufacturer PDFs and pages built to sell a VPN. We wanted one place that answers the question directly, shows the numbers clearly, and does not require an account.
How we work
Every IP address, port number and DNS server listed here is checked against the primary source: IANA and RFC registries for addresses and ports, manufacturer documentation for router defaults, and the providers’ own published details for DNS servers. When a default credential varies by model or region we say so rather than guessing. If you find an error, tell us through the contact page and we will fix it.
Privacy
The tools on this site run in your browser wherever possible. The What Is My IP tool reads your address from the connection your browser has already made and does not send it anywhere else or store it. We do not sell data, run tracking pixels for advertisers, or require sign-up for any feature. The privacy policy has the full detail.
What is coming
The site launched with the reference sections and the browser-side tools. Server-side tools such as IP lookup, DNS checker and port checker are in development and will appear on the tools page as they ship, followed by per-address pages for public IPs, ASNs and countries.
