Unimatrix supports restrictions on the IP addresses of API call requests to safeguard your SMS API calls from trusted servers. You can specify the IP addresses that are allowed to be accessed by setting up a whitelist, or the IP addresses that are forbidden to be accessed by setting up a blacklist.
This feature is an extension service and is not enabled by default. Please go to Extensions - IP Restriction in the Console to configure according to your actual needs.
Supports filling in IPv4 addresses such as
220.127.116.11 or IPv4 segments such as
18.104.22.168/24, with multiple entries separated by commas, and adding up to 50 records.
