That's all but if you disable it, it means that basically any host can 
overwrite any record and multiple hosts with the same name will 
continuously take turn to update the same record.

With "update-conflict-detection" on, the first host get to update the 
zone and after that any other hosts with the same name are rejected as 
long as the lease of the first one is valid.
