IP Address Ranges

The IP address of a discovery hint must match an Include in Rule entry in the IP address range list. If there are no included IP address ranges in an auto-discovery rule, then all address hints are considered a match. (For this case, see Tips for Configuring Auto-Discovery Rules.) Additionally, the hint must not match any entry marked Ignored by Rule. If all checks successfully match, this rule’s configuration is used for handling the hint.

  • If you are not discovering some expected devices, check your configured IP ranges to ensure that the IP addresses for those devices are included in a range and not ignored by a rule with a lower ordering number.
  • If you are discovering more devices that you want, modify the include ranges or add ignored ranges for the IP addresses of the devices that you do not want discovered. Also, determine if Discover Any SNMP Device is enabled.
