Pinging DNS gives multiple IP addresses

The above location is a Microsoft Network Load Balancing Cluster and has a Cluster IP address of 10.5.22.44 and DNS of test.com (IP and hostname not the real ones)
The cluster contains 2 servers test1 (10.5.22.56) and test2 (10.5.22.15).

When you ping the DNS name we receive ping responses from other IP addresses (e.g. 10.5.22.77 and 78 etc).
What is the reason behind this?

Start by checking your DNS in case you have a duplicate entry for test.com

Whats best way to check if duplicate entry for test.com exists?
If you are using a Windows client, try using nslookup and set the debug level high enough to see the responses that you are receiving. You can take a look here for some detail: https://www.interfacett.com/blogs/windows-troubleshooting-tip-advanced-dns-query-debugging-with-nslookup/
From unix shell, or from ubuntu shell in Windows 10

dig test.com @yourdnsserverip 

Open in new window

will answer with all records defined for your FQDN
Provide your real site [host.]domain.com for testing.

Better to test + provide a real answer, than guess.
