Oct 17, 2019 · The CIDR number comes from the number of ones in the subnet mask when converted to binary. The common subnet mask 255.255.255.0 is 11111111.11111111.11111111.00000000 in binary. This adds up to 24 ones, or /24 (pronounced ‘slash twenty four’). A subnet mask of 255.255.255.192 is 11111111.11111111.11111111.11000000 in binary, or 26 ones

Subnet mask 255.255.255.255 What is the prefix length notation for the subnet mask 255.255.255.224? A network with the subnet mask 255.255.255.0 would have what cidr block? Using cidr notation, the subnet mask 255.255.255.0 would be written as in cidr notation, the subnet mask 255.255.255.0 is represented by what prefix? The ip address of 10.240.0.0 with a subnet mask of 255.255.255.0 Netmask Converter - Bitmask | Decimal | Hex | Binary Bitmask (Bits) Dotted Decimal Hexadecimal Binary /0 : 0.0.0.0 : 0x00000000 : 00000000 00000000 00000000 00000000 /1 : 128.0.0.0 : 0x80000000 : 10000000 00000000

If you get a subnet like 192.168.0.0 with a mask 255.255.255.192, without hesitation you must calculate 256 - 192 = 64 hosts per subnets ( subtract 2 for bcast and network) 255.255.255.128 = 256 - 128 = 128 - 2
