Route destinations like 10/8 are most likely intended as a shorthand
for 10.0.0.0/8, but instead it means 0.0.0.10/8, which includes
only bits in the host part of the mask, and hence adds a route to
0.0.0.0/8. In 12.x, there was code to "do what I mean", which was
removed as part of a cleanup of old network class remnants. Given
that we have gone this long without that code, do not restore that
behavior. Instead, detect the issue and produce an error.
Specifically, if there are no dots in a numeric IPv4 address, the
mask is specified with CIDR notation (using a slash), and there are
bits set in the host part, produce an error like this for 10/8:
route: malformed address, bits set after mask; 10 means 0.0.0.10

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
For information on the CPU architectures and platforms supported by FreeBSD, see the FreeBSD website's Platforms page.
