routing only a segment of a subnet?

Sorry if this belongs on a different sub.

We have vlan with a /24 subnet: 10.0.130.0 / 24

A server on this vlan has the following static route:

route add 10.0.103.192 mask 255.255.255.224 172.16.10.1 -p 

It looks like this route is 'routing' only a segment or a subnet of my original subnet (10.0.103.0 /24)

I thought 10.0.103.0 /24 was a subnet. If so, what is 10.0.103.192 /27?

Since the default route is using 10.0.103.192 /27.. does this mean .192 and .223 cannot be used?

What is this practice of routing a subnet within a subnet called?
