The preffix length notation /27 means that 27 bits belong to the network section so the remaining (32 -27 =) 5 bits belong to the hosts section. Remember that the length of an IPv4 address is 32
Dec 19, 2019 · The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network. In TCP/IP, the parts of the IP address that are used as the network and host addresses are not fixed, so the network and host addresses above cannot be determined unless you have more information. Subnet Mask Calculator. The network address and host address are the components of IP address. IP address into the network and host address are separated by the Subnet mask. This IP subnet mask calculator helps you in finding the answer to your question of 'How to calculate a subnet mask?'. Subnet mask divides the IP address into a network address and host address, hence to identify which part of IP address is reserved for the network and which part is available for host use. Once given the IP address and its subnet mask, the network address (subnet) of a host can be determined. Default Subnet mask: 11111111.11111111.11111111.00000000 (in binary) Thus the number of bits are 8+8+8+0= 24 bits. As mentioned earlier, for subnetting in class C network, we will borrow bits from the host portion of the subnet mask. Therefore, to customize the subnet as per requirement: We take a subnet mask of 255.255.255.248 (in decimal) In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10.10.0 subnet mask 255.255.255.0 means that the subnet is a range of IP addresses from 10.10.10.0 - 10.10.10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. Subnet masks are also expressed in dot-decimal notation like an address. For example, 255.255.255.0 is the subnet mask for the prefix 198.51.100.0 / 24 . Traffic is exchanged between subnetworks through routers when the routing prefixes of the source address and the destination address differ. network network mask hosts networks total hosts /count possible available ; 24: 255.255.255.0: 256: 254: 1: 254: 25: 255.255.255.128: 128: 126: 2: 252: 26: 255.255

An IP address has two components, the network address and the host address. For example, consider the IP address 150.215.017.009. Assuming this is part of a Class B network, the first two numbers ( 150.215) represent the Class B network address, and the second two numbers ( 017.009) identify a particular host on this network.
