Esxi host does not respond to ping

Hi all,

I am trying to set up learning lab with ESXi.  I loaded esxi 6.5 and assigned static address.

I can ping the address: 192.168.1.72 which is the host.

If I ping the name Home150 it is unable to find the host.

mask is 255.255.255.0  with both dns and gateway are 192.168.1.254

ESX lists the domain as Home150.home.com but win I ping home.150.home com it returns 23.217.138.110

I can ping other computers on the network 192.168.1.xxx by name.

The dns extension lists adding  attlocal.net.

What am I missing?

If this is not the right spot, please point me to the correct location.

thanks

Kenu
