The term "IP range" refers to a range of IP addresses that are directly consecutive. IP addresses are used to identify computers and devices on the Internet, to connect to the Web, and to communicate with each other.
IP ranges are often used in networking and server environments to define specific actions or configurations for a group of devices. Like for firewall rules: firewalls can be configured to block or allow traffic based on specific IP ranges. Or for access control: by assigning specific IP addresses or ranges, administrators can restrict access to certain resources or services to prevent unauthorised access.
