### Description

```asn1
devIPRouteMask OBJECT-TYPE
SYNTAX IpAddress
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Indicate the mask to be logical-ANDed with the
destination address before being compared to the
value in the devIPRouteDest field. For those systems
that do not support arbitrary subnet masks, an
agent constructs the value of the devIPRouteMask by
determining whether the value of the correspondent
devIPRouteDest field belong to a class-A, B, or C
network, and then using one of:
mask network
255.0.0.0 class-A
255.255.0.0 class-B
255.255.255.0 class-C
If the value of the devIPRouteDest is 0.0.0.0 (a
default route), then the mask value is also
0.0.0.0. It should be noted that all IP routing
subsystems implicitly use this mechanism."
