Network diagnostics
Port checker
Test one TCP port on a public hostname or IP address from the IPGetter server.
Quick guide
What a port check means
IPGetter attempts one normal TCP connection to the public address and port you specify. An open result means a TCP handshake succeeded from this server.
A failed connection does not always mean the service is down. Firewalls, allowlists, geo restrictions and rate limits can block IPGetter while allowing traffic from somewhere else.
Plain HTTP web traffic.
Common SSH and SMTP ports, often restricted by firewalls.
The hostname is resolved and IPGetter attempts a TCP connection to the chosen public port from the IPGetter server, measuring how long the connection takes.
- Confirming a public service is reachable
- Checking common web or mail ports
- Distinguishing DNS resolution from TCP reachability problems
