IP allowlisting allows you to explicitly restrict access to specific IP addresses and/or CIDR notations for APIs. We highly recommend using this feature as an additional security protection. The feature is available for both Inbound and Outbound routes.
Enable IP allowlisting on a route:
Enter an IP or CIDR to match the IP address the request is made from. For example 172.16.254.1, 2001:db8:0:1234:0:567:8:1, 192.168.1.15/24. Multiple IP addresses could be added separated by a comma
