IP stack : Public IP
A public IP address is a unique identifier assigned to a device or network that is accessible over the internet. It plays a pivotal role in the IP stack by enabling global communication between devices on different networks. Public IPs are routable across the internet, making them essential for web servers, cloud resources, and other…

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 : Loopback
The loopback interface is a fundamental component of the IP stack, enabling internal network communications within a device. It provides a mechanism for testing and debugging network services without requiring physical network hardware. The loopback interface is identified by the IP address 127.0.0.1 for IPv4 and ::1 for IPv6, both of which are reserved specifically…

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 Datagram Access via CMD Commands
An IP Datagram is a basic unit of data that is transmitted across an IP network. At the core of the Internet Protocol (IP), datagrams are used to carry payloads (the actual data being transferred) from the source to the destination in a network. Unlike higher-level protocols like TCP or UDP, IP operates at the…
