Zabbix Network Discovery Query.

[Ajithradhakrishnan]

Hello,

I want to understand the filtering options for network discovery in Zabbix (version 7.2.4).

Current Setup:

We have configured network discovery with an IP range (192.168.1.0/24) and assigned ICMP protocol for checking availability.

The discovery results appear under Administration > Discovery, showing which IPs respond to ICMP ping.

The discovered IPs are mapped to hostnames, displaying entries like:

Testserver = 192.168.1.1 → This IP is assigned to the host interface of "Testserver".

However, if the same host Testserver has another IP (e.g., 192.168.1.2), it also appears in the discovery results under Administration > Discovery.

My Requirement:

I want secondary IPs to be excluded from the network discovery results.

The goal is to differentiate between primary and secondary IPs and prevent duplicate host entries.

This is important because we need to track which IPs from multiple ranges are added as hosts in Zabbix and which are not yet added.

Questions:

Is there any way to filter out duplicate/secondary IPs in Zabbix network discovery?

I have already tried various methods from Zabbix documentation and knowledge base, but they didn’t work as expected.

Any suggestions on additional filtering possibilities?

Note: I have added the secondary IP on the host interface, and in discovery, it shows the same hostname for both the primary and secondary IPs. I want to work with multiple IP ranges.

Let me know if there’s any possible solution for this.

Thanks,
Ajith
