![]() ![]() As you need 2 subnets, x is 1.ġ92.168.255.0 is also the common network identifier for the whole network, and its subnet mask is 255.255.255.0 In this case, the first 24 bits (i.e., 192.168.255) represent the network identifier, and the remaining 8 bits represent the host identifier.Ĭonsidering x is the number of 1 bits needed in the host identifier part of the subnet mask, 2x is the number of subnets. All the host addresses in the same network will have an identical network identifier but a unique host identifier. In general, each IP address consists of two parts: network identifier and host identifier. Say you have a network with IP addresses ranging from 192.168.255.0 to 192.168. This is how a router identifies the subnet of an IP address since data packets only contain the destination IP address. All the IP addresses in a subnet contain an identical most-significant bit group. Subnet mask (or) netmask: This is the bitmask used to identify the subnet of an IP address by applying bitwise AND operation with the netmask and the IP address.A packet forwarded to the broadcast address is broadcasted to all the addresses in a subnet. Broadcast address: This is always the last address of the subnet.Network address (or) subnet ID: This is always the first address of the subnet. ![]()
