AAP 2.5 - Proxy settings do not support CIDR notation (/24) in NO_PROXY

I am trying to define proxy setting in the extra environmental variables in Job settings like below

NO_PROXY = { 
    "HTTPS_PROXY": "http://proxy.example.com:3128",
    "HTTP_PROXY": "http://proxy.example.com:3128",
    "NO_PROXY": "127.0.0.1,localhost,.example.com, 172.20.0.0/24" 
} 

AAP doesn’t recognize the “/24” format; instead, if I define individual IP addresses, it works fine.

Is it not supported in AAP 2.5, or did I do anything wrong in this context?

Thanks
