TESTING DEVICES WITHIN YOUR LOCAL AREA NETWORK (LAN)
Download the Free Nmap Security Scanner for Linux/Mac/Windows
https://nmap.org/download.html
Nmap ("Network Mapper") is an open source tool for network
exploration and security auditing. It was designed to
rapidly scan large networks, although it works fine against
single hosts. Nmap uses raw IP packets in novel ways to
determine what hosts are available on the network, what
services (application name and version) those hosts are
offering, what operating systems (and OS versions) they are
running, what type of packet filters/firewalls are in use,
and dozens of other characteristics. While Nmap is commonly
used for security audits, many systems and network
administrators find it useful for routine tasks such as
network inventory, managing service upgrade schedules, and
monitoring host or service uptime.

Since my Local Area Network (LAN) has the IP addresses
172.16.0.1/24 I will do the following nmap scan:
sudo nmap -F 172.16.0.1/24

Wireshark is the world's foremost and widely-used network
protocol analyzer. It lets you see what's happening on your
network at a microscopic level and is the de facto (and
often de jure) standard across many commercial and
non-profit enterprises, government agencies, and educational
institutions. Wireshark development thrives thanks to the
volunteer contributions of networking experts around the
globe and is the continuation of a project started by Gerald
Combs in 1998.
