IP 195.5.2.0/24

Mask 255.255.255.0


Mask in binary 1111111.11111111.11111111.00000000


To calculate the number of possible subnets, use the formula 2n , where n equals the number of host bits borrowed.

To get at least 30 subnets we need to borrow 5 host bits from the fourth octet


25 = 32 subnets


New subnet mask in binary 11111111.11111111.11111111.11111000 is equivalent to /29

We will use the first 30 subnets

Number of hosts for each subnet will be

2h – 2 = 23 -2 = 6 hosts per subnet



The subnet list order subnet number, Subnet ID, valid host range, subnet broadcast IP
