Own hostname for each ip?

Question

linux

Hello dear community.
There is a CentOS server with four IP addresses on board.
Can you tell me if it is possible to assign a different hostname to each IP?
Thanks in advance.

Answer 1

DNS.

Answer 2

whatever you want.
by any of the hostnames, it will refer to the same machine. Most services will respond regardless of which interface the request came from (the firewall can tweak the truth).
For a web server, virtual directories can be configured to different domain names, even if they lead to the same IP.
You specify what service you need to organize

Answer 3

I haven't tried it myself, but I think it's possible, it's done in /etc/hosts.
