IP Stack : Private IP
Private IP addresses are an essential component of the Internet Protocol (IP) stack, enabling secure and efficient communication within local networks. These addresses are reserved for internal use in private networks, such as homes, offices, and data centers, and are not routable over the public internet. The Internet Assigned Numbers Authority (IANA) has designated specific…

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…

IP stack : Subnet mask
A subnet mask is an essential component of the IP stack used to divide an IP address into two parts: one for the network and one for the host. This concept is fundamental in network design, as it allows network administrators to manage and segment networks efficiently. The subnet mask enables devices on the same…

IP stack : IP4 vs IP6
The Internet Protocol (IP) stack is the foundation of modern networking, enabling communication between devices across interconnected networks. IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) are the two primary versions of IP, each with distinct characteristics and use cases. While IPv4 has been the backbone of the internet since the 1980s,…

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…
