The Discovery tab is first step to identifying network resources to add to your inventory. Here, you can use configuration files, paste text configs, or use automated scanning options to identify devices to use for discovery.
The Discovery tab allows the user to gather IP topography data via the following methods, organized as sub-tabs: DHCP, DNS, Firewall, Generic Config, mDNS, Load Balancer, Ping Scan, RIR, Router Configs, SNMP, ARP, and SSDP.

RIR discovery establishes a baseline of public space. From here, NetAudit will use the current user’s IP / provided IP, and then query the WHOIS system to find its ASN. From there, it queries again in order to discover allocations.
