Subnet Mask
This indicates the destination subnet mask of this route.
Flag
This indicates the route status.
U-Up:
The route is up.
!-Reject:
The route is blocked and will force a route lookup to fail.
G-Gateway:
The route uses a gateway to forward traffic.
H-Host:
The target of the route is a host.
R-Reinstate:
The route is reinstated for dynamic routing.
D-Dynamic (redirect):
The route is dynamically installed by a routing daemon or redirect.
M-Modified (redirect):
