546), a remainder of four equals a binary value of 1111 0000 and
the dotted decimal value of the next and last field is 240. Therefore
the first three fields of the subnet mask are 255.255.240.
If there are any remaining fields in the dotted decimal format, they
have a value of 0. Therefore, the complete subnet mask in dotted
decimal format is 255.255.240.0.
