Whatmask is a small C program that lets you easily convert between three common
|
|
subnet mask notations.
|
|
|
|
Notations supported:
|
|
|
|
Name Example
|
|
---------------------------------
|
|
CIDR /24
|
|
Netmask 255.255.255.0
|
|
Wilcard Bits 0.0.0.255
|
|
|
|
The above notations are all identical. CIDR notation commonly has a "/" in
|
|
front of the number (representing the number of bits). Whatmask can accept
|
|
these notations with or without a slash. This notation is used more and more
|
|
recently. A lot of popular routers and software supprt this notation.
|
|
|
|
Netmask notation is pretty much the standard old-school way of doing it. It is
|
|
supported by most systems (Un*x, Win, Mac, etc.).
|
|
|
|
Wilcard bits are similar to the netmask, but they are the logical not of the
|
|
netmask. This notation is used by a number of popular routers.
