The problem is, I don't have a single place that knows all the names and 
addresses of the DHCP clients -- each router assigns IP addresses for 
its own WiFi and LAN segments.

I could have a subdomain for each router: "client.r1.example.com", 
"client.r2.example.com", but then I would have to know which router a 
client was connected to at any time, if I wanted to reach the client by 
name.  And if the client moves to a different router, its FQDN changes.

My goal is to be able to say "ping client.example.com", and get the 
client's current IP address, no matter which router it's connected to.
