Grabs IP from Domain and updates the iptables
In order for this to work you need to have a comment with HOME (unless you change the script to something else) in your iptables
Then when the script runs it will get the ip from the domain name and checks it if its different than the last time
and if it is it will update the iptable
You need the Go languange installed
for ubuntu
sudo apt install golang
for arch
sudo pacman -S go
For a single run go run gip.go
If you want exec file
go build gip.go
./gip
