CSE JRF Classless Inter-Domain Routing (CIDR)

Classless Inter-Domain Routing (CIDR) 

  

• Classless Inter - Domain Routing ( CIDR ) is an alternative way to classify different IP addresses to the classification system into class A , class B , class C , class D , and class E. Also known as super netting .

• CIDR is a routing mechanism that is more efficient than the original way , ie, by dividing the IP address of the network into classes A , B , and C. The problem that occurs in the old system is that the system leaves a lot of unused IP addresses.

• CIDR ( CLASSES Inter domain Routing ) notation is used to facilitate the writing of the subnet mask to be more concise than writing the actual sub net mask notation .

• To use the CIDR notation classfull address address in class A is / 8 up to / 15 , class B is a / 16 and / 23 , and class C is a / 24 to / 28 . CIDR subnet mask of / 31 and / 32 never existed in the real network .
