Yes. Current setup runs a local DNS server which serves SRV records containing the local IP addresses and ports of services running inside FreeBSD jails. For instance, the payments service in one jail can communicate with the risk service running in another jail on the same host by sending an HTTP message to http://risk.local

Currently using dnsmasq but would like to use erl-dns once I finish wrapping it with an HTTP admin API.
