IP Address Classification

There are five classes: A, B, C, D and E in the IPv4 IP address space. Primarily, class A, B, and C are used by the majority of devices on the Internet. Class D and class E are for special uses. Each class has a specific range of IP addresses. The IP Address Classification figure shows different classes of IP addresses. These addresses differ in the number of bits assigned to the network and host ids. Within each network class, there are designated IP address that is reserved specifically for private/internal use only. Private IP address cannot be used on Internet-facing devices as they are non-routable - not allowed to be routed outside of your internal network.

Class	Public IP Range (NID)	Private IP Range (CIDR - Classless Inter-Domain Routing)	Special IP Range	Subnet Mask	Number of Networks	Number of Hosts per Network
A	1.0.0.0 to 127.0.0.0	10.0.0.0 to 10.255.255.255 Best Practices 최신 버전 사용 권장 공식 문서 참고 테스트 환경에서 먼저 검증 References Network Class Related Pages Linux Server Hardware Network Knowledge Graph Related → Network performance test → RDMA → NIC Bonding → Network → IPMI → SDN → NFS
