[sr-dev] Dispatcher reverse lookup by IP

Hi! Digging through the dispatcher source code I think this is the way IP matching works: * When loading or reloading dispatcher, hostnames are looked up to IP * When running a reverse check in dispatcher the IP address is checked against $si I don't understand if we handle DNS TTL and re-lookup the name here. Do I have to run a crontab dispatcher reload to make sure we have an up-to-date IP? How is names with multiple addresses handled - or SRV record sets? /O
