Inspect your public connection, routing evidence and service reachability. Registry country is not precise geolocation, route visibility is not an uptime test, and a TCP timeout does not prove that a port is closed.

## Choose a check

Begin with your public IP and connection details for a local network question. Use ASN and BGP lookups to inspect network ownership and observed routes. For a service problem, choose a bounded port or TCP connection check and compare its measurement location with the affected user.

## Tools in this collection

- [What Is My IP Address?](https://tamperbox.dev/what-is-my-ip): **See the public address your connection presents to the internet.**

  See your public IP, whether you are on IPv4 or IPv6, and test IPv6.
- [My Connection Info](https://tamperbox.dev/connection-info): **See how your browser actually connects, beyond the Wi-Fi signal.**

  See your TLS version, cipher, HTTP/2 or HTTP/3 and round-trip time.
- [ASN Lookup](https://tamperbox.dev/asn-lookup): **An unfamiliar IP in your logs? Find the network announcing it.**

  Find the network (ASN) that announces an IP and who it is registered to.
- [BGP Route Lookup](https://tamperbox.dev/bgp-lookup): **Investigate routing changes when a network becomes hard to reach.**

  Inspect routes for a domain, IP, prefix or ASN: origins, visibility and BGP incidents.
- [Open Port Checker](https://tamperbox.dev/open-port-checker): **Set up port forwarding? Check whether the internet can reach your port.**

  Check whether a port on your own IP is reachable from the internet.
- [TCP Ping](https://tamperbox.dev/tcp-ping): **A service works for you but not elsewhere? Compare connections from three regions.**

  Test TCP connections to a host and port from three regions at once.
- [Minecraft Server Status Checker](https://tamperbox.dev/minecraft-server-status): **Friends can't join your Minecraft server? Check its public status.**

  Check whether a Minecraft Java server is online, its players and ping.
