I'm configuring a DNS service for the first time which involves a master DNS server and a slave DNS server. On investigating why the slave zones were not updating after I make edits to the zones on the master DNS, I discovered that the serial value in the zones (on master and slave) needs to:
(a) Be different (b) Increment in the master zones in order for the files to be copied across.
Does this mean when a new client machine is added to the master zone files, I would always need to remember to change the serial value in each file? Or is there another solution for this which I'm missing?
Thanks
