"""converts an IPv6 netmask to CIDR form

|
|
According to the link below, CIDR is the only official way to specify

|
a subset of IPv6. With that said, the same link provides a way to
|
|
loosely convert an netmask to a CIDR.
|

Arguments:
|
|
mask (string): The IPv6 netmask to convert to CIDR
|
|
|
|
Returns:
|

int: The CIDR representation of the netmask
