X.X.X.80 is a valid network for a /28.

CSCve91311, which has been fixed.

The parser truncates the prefix string to 15 characters, which is the
longest possible IP address (but not the longest possible IP address
plus mask).

"10.203.165.80/28" is 16 characters.  When it gets truncated to 15
characters, it becomes "10.203.165.80/2".  Which does have host bits
set and is invalid.
