An IP address group is a collection of IP addresses that are managed or treated as a single unit for various networking purposes. These groups are commonly used in firewall configurations, network access control lists (ACLs), and routing policies. Instead of defining individual IP addresses repeatedly, administrators can create a group containing all the relevant addresses. This simplifies management and reduces the potential for errors.

For instance, a firewall rule might specify that traffic from a particular IP address group should be allowed or denied access to a network resource. This group could represent all the servers within a specific data center or a range of IP addresses assigned to a particular department. When an IP address is added to or removed from the group, the firewall rule automatically updates to reflect the change, without requiring manual modification of the rule itself.

IP address groups can be defined based on various criteria, including contiguous ranges of IP addresses, individual IP addresses, or even other defined groups. They offer a flexible and efficient way to manage network security and access permissions, especially in large and dynamic network environments. The concept allows for abstraction, making complex network configurations more manageable and less prone to misconfiguration.
