CIDR to netmask

To begin with, something basic but useful, a LabVIEW VI for converting CIDR suffix to a standard IP mask. As you know, in CIDR format the number after the IP indicates the bits that address uses. If you need to convert to a traditional subnet mask, this VI comes handy.

So, a CIDR of 24 will return a 255.255.255.0 mask, 28 is 255.255.255.240, etc. Pretty simple, but a lot of applications demand netmasks in this format.

LabVIEW still only supports IPv4, so I haven't delved into the complexities of IPv6 (we'd need a U128 data type for that).
