Add an option to resolve IP address over IPv4 only #335

Hey!

When providing my own RESOLVE_URL, there is no way to tell the resolution should be done over IPv4 only. Notably, I was not able to specify WGET_CMD as /usr/bin/wget -4. Either we could add a WGET_OPTIONS for arbitrary wget options or add a specific option to force IPv4 for resolution.

Thanks.

I had this issue too. I ended with a trick:

create a script /usr/local/lib/extra/wget4 containing /usr/bin/wget -4 $*
chmod +x /usr/local/lib/extra/wget4
set WGET_CMD to /usr/local/lib/extra/wget4
