Network administrators may need a command or tool that will display all the live hosts in their network/subnet to keep track of all the activities and for that, you can try using fping tool which works based on the ICMP echo request.
Fping rpm : https://fping.org/
To install via yum on centos/fedora/rhel
# yum install fping
After installing just execute the following command :
- fping -g 192.168.1.0/24 | grep “alive”
- fping -g 192.168.1.0 192.168.1.255 | grep “alive”
