Angry IP 
Scanner
 for Windows (I have no idea what made that IP scanner so angry, but it 
does work well).
To save you the trouble of a Google search, the following 
nmap
 syntax will scan a 
subnet and report back regarding which IP addresses are in use. You'll need the 
nmap
 
package installed first. Just replace the network address with yours:
nmap -sP 192.168.1.0/24 
keepalived
 is by no means specific to Apache. You can use it with 
many different applications and services, NGINX being another 
example. 
keepalived
 also allows you to create a load-balanced 
environment as well.
Be careful when scanning networks for free IP addresses, as 
scanning a network may show up in intrusion detection systems 
as a threat. If you're scanning any network other than one that 
you own, always make sure you have permission from both the 
network administrator as well as management before you start 
scanning. Also, if you're scanning a company network, keep in 
mind that any hardware load balancers in use may not respond 
to pings, so you may want to also look at an IP layout from your 
network administrator as well and compare the results.
