gate@ampr-gateways:~/Bin$ ./range2subnet 44.4.9.1 44.4.9.3
Your range can only be expressed by several subnets:
44.4.9.1/32 44.4.9.1 to 44.4.9.1
44.4.9.2/31 44.4.9.2 to 44.4.9.3
Alternatively you can cover the range with the single subnet:
44.4.9.0/30 44.4.9.0 to 44.4.9.3
gate@ampr-gateways:~/Bin$ ./range2subnet 44.4.9.1 44.4.9.6
Your range can only be expressed by several subnets:
44.4.9.1/32 44.4.9.1 to 44.4.9.1
44.4.9.2/31 44.4.9.2 to 44.4.9.3
44.4.9.4/31 44.4.9.4 to 44.4.9.5
44.4.9.6/32 44.4.9.6 to 44.4.9.6
Alternatively you can cover the range with the single subnet:
44.4.9.0/29 44.4.9.0 to 44.4.9.7

Okay, so how to do this? The assigned addresses are 44.4.9.1 through 6.
Do I just call each one a separate /32 subnet?

Yes, now 44.4.9.1 is there through the same gateway. It is entered as
44.4.9.1/30. Perhaps some will complain because it's not 44.4.9.0/30
but 44.4.9.0 is not assigned to me.
44.4.9.1/30 is invalid. It will not be loaded
in the Linux routing table.
