클래스풀 주소 지정이란 무엇입니까?
수년에 걸쳐 나는 "CIDR"이라는 용어를 들어왔지만 그것에 대해 별로 생각해 본 적이 없습니다. 오늘 아침 나는 그 내용을 정독했다.위키피디아 기사CIDR이 실제로는 네트워크에 대한(또는 네트워크에서) IP 주소를 생성하기 위한 알고리즘일 뿐이라는 점을 이해하면서 읽은 것입니다.
이것이 공정한 평가인가? 아니면 내가 큰 그림을 놓친 걸까? 다른 주요 용도가 있습니까?
미리 감사드립니다!

인터넷에서의 주요 용도 외에도 개인 IP 주소 범위를 대기업 네트워크로 분할하는 또 다른 주요 용도도 있습니다.

Classless Inter-Domain Routing (CIDR):
an Address Assignment and Aggregation Strategy
1. Problem, Goal, and Motivation
As the Internet has evolved and grown over in recent years, it has
become evident that it is soon to face several serious scaling
problems. These include:
1. Exhaustion of the class B network address space. One
fundamental cause of this problem is the lack of a network
class of a size which is appropriate for mid-sized
organization; class C, with a maximum of 254 host
addresses, is too small, while class B, which allows up to
65534 addresses, is too large for most organizations.
2. Growth of routing tables in Internet routers beyond the
ability of current software, hardware, and people to
effectively manage.
3. Eventual exhaustion of the 32-bit IP address space.
It has become clear that the first two of these problems are likely
to become critical within the next one to three years. This memo
attempts to deal with these problems by proposing a mechanism to slow
the growth of the routing table and the need for allocating new IP
network numbers. It does not attempt to solve the third problem,
which is of a more long-term nature, but instead endeavors to ease
enough of the short to mid-term difficulties to allow the Internet to
continue to function efficiently while progress is made on a longer-
term solution.
