Network grouping issues

For the setup to work, the 16 IPs below must be identified as
"interesting" for VPN encryption and these IPs can be identified via per
host or subnet.

If it's to be identified via host, they have to use /32 for the prefix
length i.e 10.55.32.80/32 --- this is the same as 10.55.32.80 mask
255.255.255.255. Using this method, you have to configure all 16 IPs, one
by one.

If it's to be identified via subnet, you have the choice of prefix length
as long as long as all the 16 IPs are covered i.e 10.55.32.0/24
(10.55.32.0 mask 255.255.255.0), 10.55.32.0/25 (10.55.32.0 mask
255.255.255.128), etc...
The benefit in using a subnet is you only have to define 1 subnet instead
of defining all the 16 host IPs. But, caution has to be taken in order not
to overlap w/ any existing IPs in use or possible concern of wasting
allocated IPs.
All IPs are assigned to PCs with WIndows OS
