TIL: ESXi caches IP to avoid excessive DNS lookup

Had a customer using hostname in mounting NFS and i wanted to test if DNS was a dependency for this kind of setup.

Removed the DNS and..*poof* NFS mount is still alive and kicking.
Apprently, ESXi caches the IP it resolves. Good news for people using NFS and mounted it using hostname

 

Here’s a KB on how to clear the internal cache:
