Describes that the domain weight determines proportionally how often a proxy is.! Of course this usually isnt done on the command line, but by an application. In hindsight the SIP protocol designers should probably have left the whole SIP server address resolution alone and let implementers use standard IP load balancing and failover mechanisms. If it does not already have this IP address, it then issues an iterative DNS Query to the Root DNS Server, otherwise, processing skips to step 4. Only DNS implements NAPTR and SRV records, and if you want to query them, you will have to use an API to query DNS directly (see res_init () and related functions, or more interesting third-party libraries like c-ares that support non-blocking operations).
