I think it is stupid that some online TV-channels and software suppliers demands that you must have an ip from "their" region.
Therfore I would like to know if anyone knows a way around this.
Nobody is getting hurt. There are only a few of us who are that nerdy.

Also, I think this would help secure me from all kinds of "bad things"- It would not be easy for a hacker to find an adress that does not exist.

I think proxies should do the trick. Go here.Enter the URL and select a proxy based on the country you need.

Actually, the contents of these basically are country specific and that is why they do not allow users from certain countries. You can use firefox tools to bypass such sites.
