An organization has been assigned the network number 200.25.100.0/24 and it needs to create a set of subnets that supports up to 60 hosts on each subnet. How to partition the IP address spaces to support the maximum number of networks? List all possible networks (use slash notations).

Answer #1

given ip address  200.25.100.0/24

Address:   200.25.100.0          11001000.00011001.01100100 .00000000
Netmask:   255.255.255.0 = 24    11111111.11111111.11111111 .00000000

taking and of address and netmask we get network address that is

200.25.100.0 11001000.00011001.01100100 .00000000

given maximum host is 2^6>=60

so last 6 bit is reserved for the host and first 2 bit of 4th octet is reserved for subnet address

subnet address host min host max broadcast address
200.25.100.0 200.25.100.1 200.25.100.62 200.25.100.63
200.25.100..64 200.25.100.65 200.25.100.126 200.25.100.127
200.25.100.128 200.25.100.129 200.25.100.190 200.25.100.191
200.25.100.192 200.25.100.193 200.25.100.254 200.25.100.255
