IP Knowledge Hub
Deep dive into the core concepts that power the internet. Simple explanations for complex network topics.
IPv4 vs IPv6
Understand the key differences between the legacy IPv4 protocol and the modern IPv6 standard.
What is ASN?
Learn what an Autonomous System Number is and how it powers internet routing (BGP).
What is CIDR?
Master Classless Inter-Domain Routing notation and subnet masking calculations.
IP Abuse Explained
How IP reputation works, why IPs get blacklisted, and how to maintain a clean sender score.
Why Learn Networking?
Whether you're a developer, system administrator, or cybersecurity enthusiast, understanding how data moves across the internet is a fundamental skill. It helps you debug connection issues, optimize performance, and secure your infrastructure.
Core Concepts Breakdown
TCP/IP Stack
The foundation of the internet. It defines how data is packetized, addressed, transmitted, routed, and received at the destination.
DNS & Routing
DNS is the phonebook of the internet, translating names to IPs. BGP is the postal service, finding the best path for your data.
Network Security
Protecting data in transit. Understanding firewalls, encryption (TLS), and reputation (Blacklists) is critical for trust.

Frequently Asked Questions
What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It identifies the host and its location in the network.
Difference between Static and Dynamic IP?
A Static IP is manually configured and never changes, ideal for servers. A Dynamic IP is assigned automatically by a DHCP server (like your home router) and can change periodically.
Why does subnetting matter?
Subnetting splits a large network into smaller, more efficient, and secure segments. It reduces network congestion and contains broadcasts to smaller domains.
