I'm in the same boat. I have a port knocking app that requires sending low-level packets. DNS resolution is something I need to do before I can use the typical socket() calls. Looks like CFHostGetAddressing is now deprecated, and not a lot of alternatives. I'll see if DNSServiceGetAddrInfo can work for me. I understand it's not a common use-case, but it's been an app that continues to get usage, so clearly there's a need.
