IP Address Group

What Is an IP Address Group?

An IP address group allows you to manage a collection of IP addresses that have the same security requirements or whose security requirements change frequently.

If you want to use a whitelist or blacklist for access control, you must select an IP address group.

  • Whitelist: Only IP addresses in the IP address group can access the listener. If the IP address group does not contain any IP address and you have selected a whitelist for access control, no IP addresses can access the listener.
  • Blacklist: IP addresses in the IP address group are denied to access the listener. If the IP address group does not contain any IP address and you have selected a blacklist for access control, all IP addresses can access the listener.

Notes and Constraints

  • By default, you can create a maximum of 50 IP address groups.
  • An IP address group can be associated with a maximum of 50 listeners.
