a class to represent an Ipv4 address mask
The constructor takes arguments according to a few formats. Ipv4Mask ("255.255.255.255"), Ipv4Mask ("/32"), and Ipv4Mask (0xffffffff) are all equivalent.
Will initialize to a garbage value (0x66666666)

mask | bitwise integer representation of the mask |
For example, the integer input 0xffffff00 yields a 24-bit mask
