  • IP stack : CIDR

    Classless Inter-Domain Routing (CIDR) is a modern addressing scheme used in the Internet Protocol (IP) stack to optimize the allocation of IP addresses and improve routing efficiency. Introduced in 1993, CIDR replaced the traditional class-based addressing system (Class A, B, C, etc.) by allowing for more flexible and efficient use of IP address space. It…

  • CIDR Block

    A Classless Inter-Domain Routing (CIDR) block is a method for allocating and managing IP addresses in a flexible manner, reducing wastage of IP space. In cloud environments like AWS, CIDR blocks define the range of IP addresses that can be allocated to resources within a Virtual Private Cloud (VPC) or subnet. Mastering CIDR configuration is…

  • CIDR Notation in Computer Networks

    Classless Inter-Domain Routing (CIDR) notation is a method for specifying IP addresses and their associated subnet masks in a concise format. Introduced in 1993 as an alternative to traditional class-based IP addressing, CIDR optimizes IP address allocation and routing efficiency. It is an integral part of modern networking, allowing for better resource utilization and reduced…
