value zero for these three objects.
o icmpOutRedirects
For a host, this object MUST always be zero, since hosts
do not send Redirects.
o icmpOutAddrMaskReps
For a host, this object MUST always be zero, unless the
host is an authoritative source of address mask
information.
o ipAddrTable
For a host, the "IP Address Table" object is effectively a
table of logical interfaces.
o ipRoutingTable
For a host, the "IP Routing Table" object is effectively a
combination of the host's Routing Cache and the static
route table described in "Routing Outbound Datagrams"
section of [INTRO:1].
Within each ipRouteEntry, ipRouteMetric1...4 normally will
have no meaning for a host and SHOULD always be -1, while
ipRouteType will normally have the value "remote".
If destinations on the connected network do not appear in
the Route Cache (see "Routing Outbound Datagrams section
of [INTRO:1]), there will be no entries with ipRouteType
of "direct".
DISCUSSION:
The current MIB does not include Type-of-Service in an
ipRouteEntry, but a future revision is expected to make
RFC1123 SUPPORT SERVICES -- MANAGEMENT October 1989
this addition.
We also expect the MIB to be expanded to allow the remote
management of applications (e.g., the ability to partially
reconfigure mail systems). Network service applications
such as mail systems should therefore be written with the
"hooks" for remote management.

Security Considerations
There are many security issues in the application and support
programs of host software, but a full discussion is beyond the scope
of this RFC. Security-related issues are mentioned in sections
concerning TFTP (Sections 4.2.1, 4.2.3.4, 4.2.3.5), the SMTP VRFY and
EXPN commands (Section 5.2.3), the SMTP HELO command (5.2.5), and the
SMTP DATA command (Section 5.2.8).
