Filtering a range of IP addresses

To exclude a particular range of systems, for example, 22 in the second octet of an IP address range, use a filter that includes every other possibility, as shown in Filtering by IP address. For the System Types field, select all system types.

Table 1. Filtering by IP address

Discovery filter fields	Value
IP Address Range	172.<16-21>.55.* | 172.<23-31>.55.*
System Name	*
System Description	*
SystemOID	*
System Types	<select all system types>

In general, you should use the ipExcludeList parameter in the discovery.conf file, not a discovery filter, to exclude specific systems.
