RFC950: "Since the bits that identify the subnet are specified by a bitmask, they need not be adjacent in the address. However, we recommend that the subnet bits be contiguous and located as the most significant bits of the local address."
So essentially any mask IS legal (even if not recommended). The two standard subnets notations are dotted decimal (e.g. 255.255.255.0) and network prefix (e.g. /24). So recognizing just "24" may not be terrible, but I find no precedent for doing so.
