If we have the IP address 192.168.1.2 with subnet mask 255.255.255.252 then there are four addresses in the network and we can refer to the address as 192.168.1.2/30
Are addresses outside this range also diveded into subnets of four IP addresses eg. 192.168.1.(4 to 7)?
Is it valid to have an address as 192.168.1.2/30 at the same time as 192.168.1.6/30 and both use 255.255.255.252 as subnet?
My confusion is that if I look at the Six in 192.168.1.6 it has a binary value 0000 0110 which seems like would be /29 instead of /30.
