WebNov 8, 2007 · Subnetting is the process of stealing bits from the HOST part of an IP address in order to divide the larger network into smaller sub-networks called subnets. After subnetting, we end up with NETWORK SUBNET HOST fields. We always reserve an IP address to identify the subnet and another one to identify the broadcast subnet address. WebFeb 12, 2024 · For that, they use a second number that you’ll always see in association with an IP address. That number is called the subnet mask. On most simple networks (like the ones in homes or small businesses), you’ll see subnet masks like 255.255.255.0, where all four numbers are either 255 or 0. cygwin strings
