Creating an IP Address Group

Function

This API is used to create an IP address group. You can associate the IP address group with a listener to control access to this listener.

Each IP address group can contain IP addresses, IP address ranges, and CIDR blocks. Each IP address range must be in the format of ip-ip, for example, 10.12.3.1-10.12.3.10. Both IPv4 and IPv6 addresses are supported.

Note: 0.0.0.0 will be considered the same as 0.0.0.0/32. If you enter both 0.0.0.0 and 0.0.0.0/32, either one will be kept. 0:0:0:0:0:0:0:1 will be considered the same as ::1 and ::1/128. If you enter 0:0:0:0:0:0:0:1, ::1, and ::1/128, only one will be kept.
