I assume it's the same as the IPv4 server - all the data is held 
internally in in-memory tables. The lease file is only there to 
provide persistence - it's read once only at startup and is otherwise 
never read by the server process.

For querying data, take a look at OMSHELL - I believe there are man 
pages for it.
