I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, it's always a very bad idea, to Add Hosts by using an IP Address.

You should always use DNS names....

So you will need to ensure that, all the following servers

have DNS and Reservse DNS entries in your DNS servers, and these can be resolved (ping, traceroute) from your vCenter Server.

and then remove the existing hosts, and re-add using FQDN (fully qualified domain name!).

 removing and re-adding will NOT affect running VMs.
