You could put the MAC addresses, in the format given above (ie prefix 
with "dhcp-host=" and suffix with ",ignore") into another file and read 
it from the main configuration file with

conf-file=<path to my MAC addresses>

The next release will allow the guts of dhcp-host declarations to be put 
in a file and read (or re-read on SIGHUP), so then it would be enough to 


into a file.

For completeness, if you could use a manufacturer prefix then something like


would work.
