- do not set the gateway because you can screw you internet connection
- do not set DNS because you really don’t need it
- do not set 127.0.0.1 or 192.168.0.1 or addresses from the same class as your internet connection address
- The addresses that I’m using most of the time are 10.10.10.10 or 22.214.171.124 with 255.255.255.0 as mask.
