From the original CR forum post: https://support.appsanywhere.com/hc/en-us/community/posts/6354733840285-More-Complex-IP-Range-Declarations

Allow for a range of IP's to be excluded within a larger range of allowed address.

For example,

We have a range set as follows:

139.184.0.0/16

However, within this range are staff connecting off-site via a VPN service.

We would like to exclude ranges, e.g. 139.184.134.0/23 within the above range?
