The Name Resolution probe calls multiple drivers, including:

  • A driver that gathers IPv4 and IPv6 addresses and other MIB-II data for the system.

  • A driver that gathers VPN routing and forwarding (VRF) IP addresses and route distinguisher tags from individual vendor MIBs on the system.

  • A driver that provides a unique name for the system, as described in “How discovery names a system” on page 172.

    The Name Resolution probe discovers almost all of the IP and IPv6 addresses that are available for the system, including the VRF IP addresses if the DisableOverlappingIP configuration parameter is set to FALSE. Matrix of IP-related objects created by the Name Resolution probe summarizes the IP-related objects that are created by the Name Resolution probe.
