The IP MIB Group

Most of the interesting network managment information relates to the IP subsystem. Some IP scalar objects are as follows:
 
ipForwarding
If this BOOLEAN variable is TRUE, this node is acting as an IP gateway (router). Otherwise it is a host.
ipDefaultTTL
Default TTL for datagrams originating from this node -- typically 60.
ipInReceives
Total number of datagrams received from the underlying MAC (usually Ethernet) layer by the IP subsystem.
ipForwDatagrams
Total number of datagrams forwarded (ie, routed) by this router.
ipInDiscards
Total number of datagrams discarded (ie, dropped) due to resource limitations
...plus many more

 
There are also several tables associated with the IP subsystem:
 
ipAddrTable
maintains information about each of the IP addresses on a node: netmask, broadcast, etc
ipRoutingTable
keeps track of routes associated with the node. Each route is an ipRouteEntry type.
IP Address translation table
(in MIB-II) contains entries for MAC-to-IP mapping address mapping for each interface.
