localhost entry in /etc/hosts

We have HPUX servers on 11.31.  Our localhost enty is in this format which I kinda use for years now.       localhost       loopback


There were recent changes on the DNS managed by another support group. Their recommendation is  for us to create an entry  something like: localhost


What do you think?

Re: localhost entry in /etc/hosts

I think I'd like to ask why they need a FQDN for a loopback address.

Re: localhost entry in /etc/hosts

It's just another alias to the IP address. The requisite names are already there so the extra one won't create any problems. Somebody probably Googled localhost and found an obscure document that suggests that an FQDN does something useful.
