🧭 Introduction to Network Mapping
In the world of cybersecurity and network administration, network mapping is an essential process. It helps identify all devices, IP addresses, routers, switches, and servers connected to a network. Network mapping gives a visual representation of your network infrastructure, allowing administrators to detect vulnerabilities, unauthorized devices, or configuration issues.
In simple words — network mapping is like drawing a map of your digital world. It tells you who is connected, how they’re connected, and what they’re doing.
⚙️ What Are Network Mapping Tools?
Network mapping tools are specialized software applications that automatically scan, detect, and visualize all network components. These tools gather information such as:
-
IP address
-
MAC address
-
Device type (Router, Switch, Server, Printer, etc.)
-
Open ports and running services
-
Network traffic and performance metrics
They are heavily used in penetration testing, network security auditing, and IT infrastructure management.
