I'm not entirely sure what your differentiation here is. If it's that DNS can only find addresses (lets say A records) for domain names with three "parts" (or more perhaps), then that's not the case. I can resolve siphappens.com as 38.196.86.5, for instance. > So how can the my SIP proxy server get the next hop? As you don't want to use a Location Server, per se, it should use the procedures outlined in section 1.4.2; namely a combination of A and SRV lookups. I would take a look at RFCs 1034 and 2782.
