Identity Domain Administrators and Service Administrators, by configuring an allowlist or a blocklist, can control whether Internet Protocol (IP) addresses belonging to a network can connect to an environment.
An allowlist contains rules that define which IP addresses can access an environment while a denylist contains rules that exclude IP addresses from connecting to an environment.
You use the Service Details screen of My Services to create allowlist or blocklist rules to regulate how users access an environment. While creating rules, the Identity Domain Administrator or Service Administrator identifies individual IP addresses, a range of IP address, subnets/masks, or Classless Inter-Domain Routing (CIDR) to identify the addresses that are allowed or denied access to the environment.
For detailed configuration instructions, see "Managing Internet Protocol Allowlist and Blocklist Rules" in Managing and Monitoring Oracle Cloud.
