CIDR Blocks

A system called Classless Inter-Domain Routing, or CIDR, was developed as an alternative to traditional subnetting. The idea is that you can add a specification in the IP address itself as to the number of significant bits that make up the routing or networking portion.

CIDR senin sebekeni nece böleceyini gösterir yeni senin daxili sebekeni nece ip alacaqini gösterir meselen 192.168.0.0/24 bu o demekdir ki ilk 3 reqeeme deyme onlar olduqu kimi olsun ve sen son reqemi 1 256 qeder deyise bilersen istifadecilerin ipleri bele olacaq eger 192.168.0/16 ise sen ilk iki reqeme deyme ve senin ip in 192.168.1.1 ve ya 256 ya qeder deyisir her iki birde yeni her bir ip 8 8 8 8 olmaqla 32 tamamlanır senin ise orda 16 deyir ve 24

  • When you create a subnet, you specify the IPv4 CIDR block for the subnet, which is a subset of the VPC CIDR block

  • Defines a range of IP addresses

  • CIDR = Classless Inter-Domain Routing

Defines a range of IP addresses

CIDR = Classless Inter-Domain Routing
