[OpenSIPS-Users] Enum modul

[Bogdan-Andrei Iancu]

Hi Miha,

In OpenSIPS, for any DNS lookup, the res_search() frunction from glib is 
used, function that uses the /etc/resolv.conf file for fetching the 
default DNS server.
I guess this function does not have the ability to figure out what's the 
direct DNS server and go directly there.

Best regards,
