Changes from version 1.0:
Introduced support for reporting network address, broadcast address,
number of IPs, first IP and last IP.
Made some source adjustments to facilitate compiling under
Win32, MacOS Classic and MacOS X.
Optimized a routine or two.
Cleaned up code / headers.
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.
