Is tracking 2.......

You're probably entering the wrong IP or something. Try putting the country in all lowercase. I just tried it, and it's fine.

I tried that, and entering the ip instead of the host name. and none worked….

this challenge is weird about the format. just rearrange things.

The following is taken from the HBH FAQ's page…

Tracking 2 wont accept my answer.

Tracking 2 uses scripts to collect a active IP from a large proxy list.

This means the IP for the challenge could possibly change daily.

If your answer isn't accepted, its quite possible your either:

1. Your entering details that have expired.
2. The IP comes from a country that can have various spellings. (i.e UK / United Kingdom / England)

If this happens and your positive you've entered the correct details, please try the challenge again the next day.

I got it.. I think the IP had changed.. :D
