Creating an IP Address Group

IP Address Group Overview

An IP address group is a collection of IP addresses that you can use to manage IP addresses with the same security requirements or whose security requirements change frequently.

ELB allows you to use a whitelist or blacklist for access control. If you want to configure an access control policy, 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 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 blacklist for access control, all IP addresses can access the listener.

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.
