It would probably be easiest to use a small script to generate a list of "hostnames" in whatever format you'd like for the IP(s) in the subnet that don't have any DNS records (perhaps something like 10.0.0.1 -> 10-0-0-1.noDNS.<yourdomain>, or whatever), and then add corresponding entries to /etc/hosts for those hosts.  Then, you can add the range using that list of hostnames.

Hi All,

I have many devices in our network that do no have hostnames and nor do I want to maintain DNS records for devices that do as this will be a nightmare to managed.

Is there a way I can simply add a whole subnet range to Observium without using hostname?

Cheers,

Ivan
