Subnetting is a fundamental concept in computer networking, particularly in IP addressing, where a large network is divided into smaller, manageable sub-networks. This division helps optimize network performance, enhance security, and efficiently utilize available IP addresses. In subnetting, a network administrator creates subnets by borrowing bits from the host portion of an IP address, dividing the address space into multiple smaller segments.
CIDR (Classless Inter-Domain Routing) notation is a method used to represent IP addresses and their associated network prefixes. It allows for more flexible allocation of IP addresses compared to older methods like classful addressing. CIDR notation expresses an IP address followed by a slash “/” and a number representing the number of bits in the network prefix. For example, the CIDR notation “192.168.1.0/24” indicates that the first 24 bits of the IP address “192.168.1.0” represent the network portion, leaving 8 bits for host addresses.
The CCNA Online Training Course is an ideal platform to learn about subnetting and CIDR notation comprehensively.

CIDR (Classless Inter-Domain Routing) notation is a method used to represent IP addresses and their associated network prefixes. It allows for more flexible allocation of IP addresses compared to older methods like classful addressing. CIDR notation expresses an IP address followed by a slash "/" and a number representing the number of bits in the network prefix. For example, the CIDR notation "192.168.1.0/24" indicates that the first 24 bits of the IP address "192.168.1.0" represent the network portion, leaving 8 bits for host addresses.
