Hello Managers,
yesterday I wrote that including in the xfrnets option (named.boot file)
host addresses instead of network ones gave the warning messages in the
daemon.log file "mask problem" during restart of named.
Thanks to those who answered:

Ian Mortimer gave the solution:

I followed this advice and now the xfrnets line looks like:
xfrnets 193.124.36.33&255.255.255.255 212.20.31.125&255.255.255.255
and restart is smooth.
Ian also replied on my question about the book:
