1. Which file stores the computer's host name?

/etc/sysconfig/network

2. Which file stores the static IP addresses ?

/etc/sysconfig/networking/devices/ifcfg-eth1

In my opinion the file is:

/etc/sysconfig/networking/profiles/default/hosts

How about:

/etc/hosts

4. Which file stores the DNS servers IP addresses ?

/etc/sysconfig/networking/profiles/default/resolv.conf

I think the file is:

This file stores information like computer's hostname and default gateway.
This file looks like

NETWORKING=yes
HOSTNAME=mohak
