mDNS Insight listens to multicast DNS (mDNS, also known as Bonjour or Zeroconf) on the local network, and lists each device it finds along with the DNS-SD services it advertises: printers, speakers, smart home hubs, file shares and anything else that announces itself. It decodes what those services say about themselves, so a printer's TXT records read as a model name and a list of paper sizes rather than a wall of key=value pairs.
Open it from your desktop's application menu to watch the network live in a web UI that opens in your browser. Or run it from a terminal:
mdns-insight # discover for a while, then report
mdns-insight -output-format=json # the same report, for scripts
mdns-insight -webui # the live web UI, no browser
mdns-insight -open # the live web UI, in your browser
The web UI listens on this computer only, at a port the system picks. -webui=ADDR serves it elsewhere, for example to reach it from another machine on a network you trust.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install mDNS Insight, simply use the following command:
sudo snap install mdns-insight --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
