Change the 255s to all 0s That means one and only one host
You don't really need the wildcard mask, but if you use it the syntax is 0.0.0.31 (this is an example for the /27 CIDR notation)
Yes on the no auto summary
Here's a quick primer
255.255.255|.0 The 3 255s define the network and the 0 defines the number of hosts in the network.. Since this is commonly called a Class C network, you can have 1 network with up to 254 hosts
Let's say your subnet mask is 255.255.255.192 On this you can have 4 networks with up to 62 hosts per network. So each network could be one for Sales, one for Engineering, one for HR, etc
