The helper to use depends on the network environment around the submitter, so some experimentation will probably be needed to choose the correct one. éN)ÚSetÚListÚCallable)ÚreturncCsTt d¡ddl}| |j|j¡}| d¡| ¡d}| ¡t d |¡¡|S)zâFinds an address for the local host by querying the local routing table for the route to Google DNS.
