Pinging DNS gives multiple IP addresses

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

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

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/

Provide your real site [host.]domain.com for testing.

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