Failing to parse IPv6 addresses #31559
Description
Describe the bug
When I try to define an Application Gateway WAF custom rule with multiple Ipv6 addresses I'm getting an error.
This issue appears when using 2 IPv6 address. When using a single IPv6 address or using 2 IPv4 addresses, there is no error.
The IPv6 feature in Application Gateway WAF is currently in Private Preview, so please contact me for testing the issue/fix in production environment if necessary.
