/28
/29

Reduced IP address point to point means only two addresses by /30 CIDR notation. So, No of hosts/subnet - 2.

Subnet mask: 11111111.11111111.11111111.11111100/30 - 255.255.255.252/30.
point to point which are directly connected or through wireless connection but there are only two IP's.

For ex:-192.168.100.100/30.

Subnet :-255.255.255.252.
Binary :-11111100.
Network =6.
Hosts=2.

This above use on point-to-point WAN links in order to reduce the waste of IP.
