How to test what filtering method your ISP uses

If your ISP does IP based filtering(which is pretty unlikely), you can't do much about it except using proxies. In other scenarios, you can check for DNS level filtering very easily, see the bypass section below. DPI is way harder but we'll get to that. To see what filtering system they use, first test the DNS filtering bypass method. If it doesn't work, it's DPI.

Warning: Your ISP may be (and probably is) using multiple filtering methods like DNS and DPI combined.
