Localhost name and IP change?

[Bitflogger]

Hello, I'm running 5.5.0, 64-bit, VM, CentOS 7

I asked recently about changing the name of localhost to FQDN. That seemed to be OK with support folks.

Well, I have now been asked: Can the IP can be changed from 127.0.0.1 to the result of: nslookup <fqdn> ?

I'm not entirely clear what the question is - localhost should usually always point to a 127.0.0.1 while a fqdn can resolve to an actual(routable, accessible by other machines, etc...) IP address. Does this help answer your question? If not, please provide more detail.

Hello,

My support staff wants to change 127.0.0.1 to the actual IP number, for the localhost definition. Its not a big deal if I say "NO" but I'd like a reason to do so, namely your recommendation.

localhost should remain pointed at 127.0.0.1.
