I am setting up some Virtual Servers on a platform different from ESX called Virtuozzo.
I just checked with our admin on what the best method is for adding servers and he said to pick a high IP on our subnet. I've done that and the server seems to function but one cannot ping the machine name as is possible when the IP has been "added to DNS". Our admin says for right now, we don't need to add it.
I'm trying to understand because I think I may have given him the "blank stare" when he said that.
In brief, what is the purpose of DNS. Why is it OK to leave it out?
