Network Mapping
Network mapping uses a process to discover and visualize assets by actively probing them. Nmap sends both TCP and UDP packets to a targeted machine. These are called probe packets. A probe packet is a packet used in an active tool to collect information on a network segment of interest. Data is collected after sending those probe packets that hop from node to node and asset to asset, which returns that information to Nmap.
If you were to scan 65,536 ports on every single machine in your ecosystem, this scan could take an astronomically long time and is really unnecessary. Occasionally, you may hear someone refer to a host discovery scan as a ping scan. In Nmap, you could choose to skip the ping itself and use other targeted methods to find the active hosts on your network.
Network environments are all different; therefore, host discovery needs are going to be very different. The hosts on your network serve multiple purposes, and from a priority standpoint, not all assets...
