Network mapping is a process of creating a visual representation of the devices, connections, and topology of your network. It can help you monitor, troubleshoot, and optimize your network performance, security, and efficiency. In this article, you will learn about some of the tools that you can use to map your network for a new project.
Mapping your network can provide you with several advantages. You can identify the physical and logical layout of your network, including devices, cables, switches, routers, firewalls and servers. Furthermore, it can detect any issues or anomalies in your network, such as misconfigured devices, faulty connections, unauthorized access or bandwidth bottlenecks. Additionally, it can help you plan and implement changes or upgrades to your network, such as adding new devices, expanding the network or improving the security. Finally, mapping your network can enable you to document and report your network status, performance and configuration to stakeholders, clients or auditors.
Mapping your network is paramount for several reasons. First, you want to have a bird's eye view of your IT assets and how they are connected. By mapping, you uncover potential vulnerabilities and inefficiencies and better understand what can or should be changed in the future, when you want to scale infrastructure, for example. A well-documented network map is invaluable for audits, communicating with stakeholders, and having a clear picture of your infrastructure's health and efficiency. First, you map it, and then you Master it!
Sem controle nada será eficiente, ent?o mapear a rede para saber os equipamentos que est?o conectados e catalogar estes equipamentos para saber o que est?o realizando é a eficiência que o administrador da rede deve ter. Realizar um scan na rede atrás dos equipamentos é o início.
In order to manage any network, you need a clear and detailed network map. It allows you to see areas of weakest, particularly single points of failure. It also allows you to more easily manage projects with regards to upgrades and asset management. Knowing your network and where the essential routes are will help make your network more resilient and offer a more proactive model to your work.
mapping network is very important is helps to manage and plan for future extensions of your network, you need detailed map of the structure for easy planning. and it also helps for easy troubleshooting at a single point or the other.

Go to tool for me has always been Visio. Or a cocktail napkin if I am not near a computer. But I am always near a computer so have not drawn a cocktail napkin network for about 25 years.
When it comes to network mapping, there is a range of tools available, from simple to complex, free to paid, and manual to automated. It's important to consider your needs, budget, and preferences when selecting the right tool. Common types of tools include network scanners, mappers, and analyzers. Network scanners detect devices and connections on the network, such as IP addresses, MAC addresses, device names, and operating systems. Network mappers create visual diagrams of the network topology and hierarchy. Network analyzers monitor and measure traffic performance such as bandwidth usage, packet loss, latency, errors, and protocols. Examples of these tools include Nmap, Angry IP Scanner, Advanced IP Scanner, LanTopoLog, SolarWinds Network Topology Mapper, Microsoft Visio, Wireshark, PRTG Network Monitor, and Nagios.

Antes de avaliar as ferramentas avalie o quanto e onde haverá mais variáveis neste processo. Avalie a empresa como um ambiente, a conex?o com a internet e também a nuvem. Se o processo for suportado pela rede local, se houver demanda hibrida ou se ele demandar servi?os em nuvem (Cloud). Embora medir o uso, tráfego, capacidade de resposta das conex?es, para cada ambiente terá que habilitar alertas e precisar o entendimento dos mesmo. Saber dos alertas poderá ser um facilitador de solu??o e gest?o de crise.
Come?ar aos poucos é o mais importante, pois querer utilizar tudo de uma vez logo, acaba gerando muitos dados e n?o conseguindo realizar a análise com êxito, ent?o come?ar escaneando a rede para catalogar os equipamentos para depois utilizar outra ferramenta para realizar uma análise mais profunda.
The mentioned Angry IP Scanner is an excellent tool for a start. It's user-friendly and perfect to identify all active IP addresses quickly. One of the most annoying issues System Admins encounter is IP conflicts. It is annoying because IP conflict is easy to fix and, in essence, is not a big deal - but how it affects everything involved makes itself a huge deal. Maintaining an up-to-date map of your network's IP addresses will give you a tool to figure out IP conflict in minutes, if not seconds. An Angry IP Scanner is invaluable. Oh, and it's free.
Para mapear eficientemente sua rede para o novo projeto, recomenda-se o uso de ferramentas para descoberta de dispositivos, para análise de tráfego e para avalia??o de vulnerabilidades. Essas ferramentas fornecem insights cruciais para a configura??o adequada, seguran?a e otimiza??o da infraestrutura de rede.
To map a network effectively, you'll need various tools such as network discovery tools like Nmap or SolarWinds, which scan and identify devices on the network. Network mapping software like Visio or Lucidchart helps visualize network topology and connections. Additionally, tools like Wireshark or Tcpdump capture network traffic for detailed analysis. SNMP (Simple Network Management Protocol) monitoring tools provide insights into device status and performance metrics. Finally, documentation tools like Confluence or OneNote help organize and record network maps, configurations, and notes for future reference.
Mapping your network may vary depending on the tools you use, but generally, it involves defining your network scope and objectives, choosing the right tools for the job, scanning the network, mapping it, and analyzing it. To define your network scope and objectives, decide what parts of your network you want to map and why. For example, do you want to map the physical or logical topology? Do you want to map the network for troubleshooting, planning, or documentation purposes? To choose the right tools, consider your network scope and objectives. Then use a network scanner to discover devices and connections on the network. Use a network mapper to create a visual diagram of your network based on the data collected by the scanner. Finally, use a network analyzer to monitor and measure traffic and performance of your network. You may need to interpret and act on the data collected by your analyzer.
Escanear a rede já é o ponto de partida para ter no??o dos equipamentos e como eles est?o dispostos na rede, podendo em um segundo momento realizar uma verifica??o física e com esta confirma??o visual, registar estas informa??es num sistema chamado Netbox para ter estas informa??es centralizadas num sistema web.
Utilize diagramas de topologia para visualizar a arquitetura e identificar possíveis gargalos. Considere também a implementa??o de scanners de vulnerabilidadespara avalia??o de possíveis falhas de seguran?a e garantia da robustez da infraestrutura.
Define your goals, choose tools like Nmap or Wireshark, scan and visualize connections, analyze data flow for efficiency, conduct security checks, and keep your map updated to reflect changes. It's a dynamic process that ensures your network remains secure, well-organized, and ready for future advancements.
