How many bits are in a subnet mask
WebAug 30, 2016 · By default, the subnet mask for a Class C IP address class is set to 255.255.255.0, meaning that the first 3 octets (24 bits) in an IP address are used to identify the network ID, and the last octet (8 bits) are … WebThe reason for subtracting 2 is that the first address in each subnet is reserved as the network address, and the last address is reserved as the broadcast address, making them unusable for hosts. In summary, a subnet mask of 255.255.255.248 has 29 network bits and 3 host bits, allowing for 6 usable host addresses per subnet.

Class address ranges: Class A = 1.0.0.0 to 126.0.0.0 Class B = 128.0.0.0 to 191.255.0.0 Class C = 192.0.1.0 to 223.255.255.0 Reserved address ranges for private (non-routed) use (see RFC 1918): 10.0.0.0 -> 10.255.255.255 WebIn the above example, the subnet mask consists of 26 bits, making it 255.255.255.192, leaving 6 bits for the host identifier. This allows for 62 host combinations (2 6 −2). In general, the number of available hosts on a subnet is 2 h −2, where h is the number of bits used for the host portion of the address.
WebDec 27, 2024 · The first 24 bits (the number of ones in the subnet mask) are identified as the network address. The last 8 bits (the number of remaining zeros in the subnet mask) are identified as the host address.
