Understanding Subnetting:
Original Network: 192.168.1.0/24 has a subnet mask of 255.255.255.0, which allows for 256 IP addresses (including network and broadcast addresses).
Objective: Divide this network into two equal subnets.
Calculating Subnet Mask:
New Subnet Mask: To divide 192.168.1.0/24 into two equal halves, we need to borrow one bit from the host portion of the address, changing the subnet mask to 255.255.255.128 (/25).
Subnet Breakdown:
First Subnet: 192.168.1.0/25 (192.168.1.0 - 192.168.1.127)
Second Subnet: 192.168.1.128/25 (192.168.1.128 - 192.168.1.255)
Verification:
Each subnet now has 128 IP addresses (126 usable IP addresses, excluding the network and broadcast addresses).
