COMPUTER CENTER / UTILITIES
What is my IP? Connection and proxy indicators
See the IP address reaching Computer Center, network registration and available proxy or Tor indicators. Understand what a website can observe.
My IP & connection
See the IP address reaching Computer Center, network registration and available proxy or Tor indicators. Understand what a website can observe.
How to use this tool
Run the check without entering a target. The result uses the actual connection address seen by our server, then looks up available network registration and Tor exit information. It also shows relevant request headers that may indicate forwarding.
Reading the results
There is no reliable universal test that detects every VPN or proxy. Shared networks and carrier NAT can put many people behind one address, while proxy headers can be absent or supplied by a client. The result separates observed evidence from conclusions that cannot be verified.
