What is an IP address?

An IP address is a logical, numerical label assigned as a unique entity to each device in a network to locate the host/system through the network ID & Host ID present in the IP address

What is CIDR?

Classless Inter-Domain routing reduces the wastage of IP addresses by extra required number of IP address to the users. It represents the IP address along with special number (/n) to specify the number of bits present in the network ID.
