Something like this may help:
domtrans f911.n130.z1.fidonet.org ratznest.r19.fidonet.org
Although, (1) there is no such thing as "Region". This Fidonet concept
is in no way mapped to the addressing scheme (I assume that 'r19' stands
for region?). And (2), the person in charge for fidonet.org probably
did a wrong thing when (s)he registered something without a zone.
