This test allows you to port scan your connecting IP address. To prevent abuse, you can not change the target address.
Fire-walled hosts may take up to 30 minutes to check or timeout, especially with UDP, this is generally a good thing.
You may however be behind a proxy, we do our best to get your actual IP address, but in some cases, this may not be possible.

You have connected via IPv4 from, this is the IP we will check.
