When I specify an ip address for inclusion in UEM monitoring, the interface always returns this ip address with /32 appended. What does this mean exactly?
It is asking you to provide the subset mask.
Is this Private IP or Public which you are excluding? If you know the information then you will have to put the IP with notation e.g. 22.214.171.124/8
Just check what is the exact subnet mask. Defaults are 8, 16, 24 and 32 for the IPv4
To add more context, the /32 is reducing the IP range to one, so it is specifying a single IP address.
This tool looks pretty handy for figuring out the mask(s) you would need for any given range of IPs:
It also has a nice, succinct definition of CIDR there.
Google CIDR for much more information that you would ever want on this topic...
