I'm curious how y'all handle DNS if you're running a multi site installation and allowing domain mapping. Do you manage DNS for your clients? Do you give them the server's IP address and send them on their way? Something else?
We have a custom DNS server that we've been using for about 18 months. It ties into the domain mapping plugin, so our customers don't have to do anything but add their domain there. Right now it's pretty custom to our situation, but I'm thinking about releasing it as a service, and I'm curious if anyone out there is interested, or if there are any better solutions out.
