Why is my subnet mask 255.255.248.0? - Windows 7 Help Forums
This subnet calculator can help you with the following tasks: Identify subnet parameters for a given IP address and subnet mask (or CIDR prefix). Display subnet parameters for a number of consecutive subnets of the specified length. Enter IP address value either in dot-decimal notation (e.g., 10.1.1.5) or in CIDR notation (e.g., 10.1.1.5/24). How to Understand IP Address and Subnet Mask? | FS Community If the subnet mask example is 255.255.255.0, and since 255 in binary notation equals 11111111, so the subnet mask is: 11111111.11111111.11111111.0000000. Lining up the IP address and the subnet mask together, the network and host portions of the address can be separated: 11000000.10101000.01111011.10000100 -- IP address (192.168.123.132 Subnetwork - Wikipedia 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. A router serves as a logical or physical boundary About Slash Notation Convert the decimal representation of the subnet mask to a binary representation. Count each “1” in the subnet mask. The total is the subnet mask number. For example, to write the IPv4 address 192.168.42.23 with a subnet mask of 255.255.255.0 in slash notation: Convert the subnet mask to binary. In this example, the binary representation of
