Hi,

Can you be more specific as to why you think there's a problem?
FreeBSD supports non-contiguous netmasks - they don't have to
be composed of a series of binary ones followed by all binary
zeros.  When a netmask is non-contiguous, the system shows it
as a hex value rather than as a number of one-bits.

Unless you've got any specific problems with this, I'd like
to close this as a feature not a bug.
