Not working on IRAN server

[EbadiDev]

I just tested this script on my Iran Server and here is my results:

my setup was on Iranian server which 8.8.8.8:53 is open on it
and I can connect to slipstream using 8.8.8.8:53 and base on recommended settings I did --auto and 443 port

Also, could you make DNS scanner to support IP range ? slipnet app is already having the best DNS scanner
it would be awesome if you make it similar to slipnet application

right now it does not support IP range:
