Read top to bottom, left to right, like a newspaper. Prefix length and equivalent decimal and hexadecimal notation is given at the top of each column. Example: /8, /16, /24 and /32 are equivalent to 255 or FF in the appropriate octet. In a given column, if the shading in one row is the same as the shading in the next row, then the two addresses are part of the same subnet.
