Netværksmappere

Netværksmappere, often referred to as network mappers, are tools and techniques used to explore and visualize the topology of a computer network. These tools discover devices connected to a network and illustrate the relationships between them, such as how they are interconnected and communicate.

The process of network mapping typically involves sending out probes or requests to network addresses. These probes can be of various types, including ping requests (ICMP echo requests), ARP requests, or SNMP (Simple Network Management Protocol) queries. By analyzing the responses received, a network mapper can identify active hosts, their IP addresses, MAC addresses, operating systems, and the types of services they are running.

The visualization of network topology can take many forms, from simple lists of devices to complex graphical diagrams. These diagrams often show routers, switches, servers, workstations, and the links connecting them. Some advanced network mappers can also track network traffic flow and identify potential bottlenecks or points of failure.

Network mapping is a crucial practice for network administrators and IT professionals. It aids in network management, troubleshooting, security audits, and capacity planning. By having a clear understanding of the network's layout and the devices within it, administrators can more effectively monitor performance, identify security vulnerabilities, and respond to incidents. Understanding the network structure is fundamental to maintaining a stable and efficient network environment.
