The IP address range 112.122.64.0 is a group of 16,384 internet addresses that can be used by organizations or Internet Service Providers (ISPs) to connect their devices or provide internet services to customers.
When a device or computer is connected to the internet, it is assigned a unique IP address that identifies it on the network. The IP address consists of a series of numbers separated by dots. The IP address range 112.122.64.0 includes a block of IP addresses that fall within the range of 112.122.64.1 to 112.122.127.254.
CIDR stands for Classless Inter-Domain Routing and is a method used to allocate and manage IP addresses on the internet. It allows network administrators to divide large blocks of IP addresses into smaller subnets, which can be assigned to individual devices or networks.
In traditional IP address allocation, there were three classes of IP addresses: Class A, Class B, and Class C. Each class had a fixed number of bits assigned to the network portion and the host portion of the IP address. This led to the inefficient use of IP addresses and the exhaustion of available IPv4 addresses.
CIDR notation is a way of representing IP addresses that makes it easier to manage and allocate them. The notation 112.122.64.0 indicates that the first 18 bits of the IP address are used to identify the network, while the remaining 14 bits can be used to identify individual devices on the network.
CIDR has become the standard method of IP address allocation and management on the internet. It has significantly increased the efficiency of IP address usage and has helped to address the issue of address exhaustion.
