IP Filtering
When creating a new API Client, it is possible to set up IP filtering using CIDR blocks. This enables the licence administrator to only allow access from IP addresses within a certain range.
Example
The WISEflow production environment uses multiple IP addresses for communication, one of them being:
52.212.206.254
If I want to add an IP filter that only allows a single IP, use /32 as a suffix:
52.212.206.254/32
This indicates that all the 32 bits in the IP address are fixed.
Similarly, to add a range of seven IP addresses to a filter, use the /29 suffix indicating an IP range:
52.212.206.248
52.212.206.249
52.212.206.250
52.212.206.251
52.212.206.252
52.212.206.253
52.212.206.254
This indicates that only 29 bits in the IP address are fixed, providing a range of seven IP addresses that can be used. The same principle applies to subnets.
