Mar 27, 2018 · The subnet mask is the classical way of representing which bits are part of the network portion of the address vs. the host bits of the address. The subnet mask for a /24 network is 255.255.255.0 or frequently in hex 0xffffff00.
what is a subnet mask? | AnandTech Forums: Technology Jun 14, 2002 Guide to Subnet Mask (Subnetting) & IP Subnet Calculator #2) The bits corresponding to the subnet mask with all 1’s represent the network ID as it is a class A network and the first octet represents the network ID. The bits corresponding to all 0’s of the subnet mask is the host ID. Thus the network ID is 10 and the host ID is 20.12.2 #3) From the given subnet, we can also calculate the IP range of a particular network. What Is a "Subnet Mask"? - Ask Leo!

Jun 10, 2020 · A2-Yes you only need 8 bits for 100 hosts and both subnet masks would give you that. A subnet mask of 255.255.255.0 would give you lots of networks (2 16) and 254 hosts. A subnet of 255.255.0.0 would give you lots of hosts (approx 2 16) and 256 networks. A3 – the network has 8 bits and so does the node component. 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. Determine Default Subnet Mask: Each of Classes A, B and C has a default subnet mask, which is the subnet mask for the network prior to subnetting. It has a 1 for each network ID bit and a 0 for each host ID bit. For Class C, the subnet mask is 255.255.255.0. In binary, this is: 11111111 11111111 11111111 00000000

Oct 18, 2018 · To use the /22 subnet mask you need to use the instruction or contact the professionals. The instruction is attached to the mask upon receipt. But if for some reason the instructions were not there, you can find the instruction on the Internet. (Be careful, no one is responsible for materials posted on the Internet).

In binary, this is: 11111111 11111111 11111111 00000000 The subnet mask is the network address plus the bits reserved for identifying the subnetwork -- by convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address. In this case, therefore, the subnet mask would be 11111111.11111111.11110000.00000000.
