In each of the conversions below, the binary octets of the 32 digit dotted binary number can be converted into a decimal number as outlined below in the individual tables. The final 4 decimal numbers of each conversion are then joined using a decimal dot between the numbers to give a final dotted decimal value.
i) 11111111.11111111.11111100.00000000
[Table]
Hence:
128 + 64 + 32 + 16 + 8 + 4 + 2 +1 (= 255). 128 + 64 + 32 + 16 + 8 + 4 + 2 +1 (= 255). 128 + 64 + 32 + 16 + 8 + 4 + 0+0 (= 252). 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 (= 0)
Dotted decimal format = 255.255.252.0
