The first mode (which is how prior +versions worked) is to invoke Whatmask with only a subnet mask as the +argument. In this mode Whatmask will echo back the subnet mask in four +formats, plus the number of useable addresses in the range. - Name Example - --------------------------------- - CIDR /24 - Netmask 255.255.255.0 - Wilcard Bits 0.0.0.255 +Netmask Notations supported: -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 support 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. + Name Example +--------------------------------- + CIDR /24 + Netmask 255.255.255.0 + Hex Netmask 0xffffff00 + Wilcard Bits 0.0.0.255 |
