While performing discovery for a network there is found a blocking limitation. Scanning for a subnet is not efficient when scanning for a network-range such as IP.IP.IP-IP.IP ( 10.10.1-255.1 ), in this example it is used to scan for gateways supporting snmp, ssh, http, https and responding to icmp. If this matches there is a router or switch present and it should be monitored.
This can easily be done using nmap but the input type is not supported in zabbix which only permits IP.IP.IP.IP-IP not a variation on this. If using nmap from zabbix is permitted in such way this has not been documented.
I could not find a page that documented how to make a script for this with nmap. Especially since the input type validates against IP.IP.IP.IP-IP
