Network map/Host Discovery

Network mapping for discover hosts and topology in a LAN. Is the previous step for tapping in the web or attack a host.

There are many tools fot this. I remember two good tools in my times, Iris, Retina, not free and I don’t know how are good now. But with NMAP you can do this.

For view the hosts in company lan:
nmap -sL
Too much hosts, I try the next command for less hosts. This limits to the subhost :
nmap -sL
Or in a personal LAN we could do:
nmap -sL
