As I wrote: I can't find any information on whether localhost is needed for /etc/hosts on Linux (on Windows it's not), but the example in "man hosts" says its "desirable"

Is it OK?

Code:

# cat /etc/hosts
127.0.0.1 localhost
127.0.0.1 example.net example
1.2.3.4 www.example.net example.net

You have example.net assigned to both 127.0.0.1 and 1.2.3.4 - only the first IP found for a hostname applies.

What is 1.2.3.4 supposed to indicate?

The /etc/hosts file is used for requests originating from that server - it does not apply externally. (For that you need to configure DNS records on the nameservers.)

With a correct "/etc/hosts" and "/etc/hostname", when I SSH to a web server that its global IP address is "1.2.3.4" and "ping localhost" and "ping example.net" then the ping command must show what IP address?
