Are IP ranges (IP1-IP2) supported in mynetworks,

If so, in what format?

192.168.0.10-192.168.0.100
192.168.0.10-100

According to the documentation you can specify subnets, but not
arbitrary ranges.

netmask to the rescue:
~$ netmask -c 192.168.0.10:192.168.0.100
   192.168.0.10/31
   192.168.0.12/30
   192.168.0.16/28
   192.168.0.32/27
   192.168.0.64/27
   192.168.0.96/30
   192.168.0.100/32

So that's what you want to put into your mynetworks table in order to define the range you mean in as few networks as possible.
