Wwhitelisting Webhook IP

[jerome mourey]

Hello, 

I'a trying to whitelist IP of incoming webhook, the documentation state I must had those 4 IP addresses in my system

• 104.192.136.0/21
• 34.198.203.127
• 34.198.178.64
• 34.198.32.85

I am a bit confuse for the first one. What does it mean ? Both 104.192.136.0 and 104.192.136.21 should be added or a range from 104.192.136.0 to 104.192.136.21 should be added or something else ? 

Thanks in advance for the help.

Hi Jerome, welcome to the Community :) 

The first one is indeed a range, but that doesn't mean is from 0 to 21, it's a bit more complex than that. You can use an IP Subnetting calculator to obtain that range, in your case:

HostMin:   104.192.136.1      
HostMax:   104.192.143.254 

You can learn a bit more about it at Subnetting.

Hope that helps!
