From the Subnet of 192.168.1.64/26 (i.e. 192.168.1.64-192.168.1.127) used previously we need 8 Hosts/Subnet

192.168.64.0/26

Requirement : 8 Hosts/Subnet

2^4 = 16 Hosts/Subnet Usable Hosts = 2^n (host bits) -2 = 2^4-2 = 16-2 = 14 Usable Hosts/Subnet New Mask = /32-/4 = /28 New IP: 192.168.64.0/28

192.168.64.0/28 (First NID)

192.168.64.1/26 (First Host IP)
