Online VPN Server Checker

VPN checker tests TCP connectivity to common VPN ports on your servers. It detects open ports (OpenVPN, PPTP, SSTP), measures response latency and shows geolocation – all without installing any software.

What format should VPN servers be added in?
If you only have an IP or hostname: IP or hostname – checks all standard VPN ports automatically
If you want to check a specific port: IP:PORT
P.S.: Checks TCP connectivity to ports 1194, 1723, 443, 8443 and 4443

How Does the VPN Checker Work?

The VPN checker tests TCP connectivity to well-known VPN ports on your servers directly from our server infrastructure. For each host, it simultaneously probes ports 1194 (OpenVPN), 1723 (PPTP), 443 (SSTP/OpenVPN), 8443 and 4443 – and reports which ones responded, how fast, and from what country.

This is a port-level availability test: it tells you whether the VPN service is listening on a port, not whether the full VPN tunnel can be established (that requires credentials).

How to Use the VPN Checker

Paste your VPN server list into the text field, one server per line. Supported formats:

  • IP or hostname – scans all standard VPN ports automatically
  • IP:PORT – checks that specific port only

Click Start checking and results will appear in real time as each server is tested. Use the filters on the right to show only specific protocols or hide unreachable servers.

Why Check VPN Servers?

VPN servers can become overloaded or go offline without notice. Regular availability checks help you maintain a reliable list of working servers, avoid connection delays, and quickly identify which protocol and port is fastest for your location.
