IP address: 15.84.25.84          Netmask: 255.255.255.0         Hostname: server.rootadminz.com               Domain name: rootadminz.com               Gateway: 15.84.25.83          DNS Server 1: 8.8.8.8                  DNS Server 2: 4.4.4.4

 

To configure static IP address in RHEL / CentOS / Fedora, you will need to edit:

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

 

Where in the above "ifcfg-eth0" answers to your network interface eth0. If your interface is named “eth1" then the file that you will need to edit is "ifcfg-eth1".

 

Let’s start with the first file:

# vi /etc/sysconfig/network

 

Open that file and set:

NETWORKING=yes
HOSTNAME=server.rootadminz.com
GATEWAY=15.84.25.83
NETWORKING_IPV6=no
IPV6INIT=no

 

Next open:

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

 

Note: Make sure to open the file corresponding to your network interface. You can find your network interface name with ifconfig -a command.

 

In that file make the following changes:

DEVICE="eth0"
BOOTPROTO="static"
DNS1="8.8.8.8"
DNS2="4.4.4.4"
GATEWAY="15.84.25.83"
HOSTNAME="server.rootadminz.com"
HWADDR="00:19:99:A4:46:AB"
IPADDR="192.68.0.100"
NETMASK="255.255.255.0"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="8105c095-799b-4f5a-a445-c6d7c3681f07"

 

You will only need to edit the settings for:

DNS1 and DNS2
GATEWAY
HOSTNAME
NETMASK
IPADDR

 

Other settings should have already been predefined.

 

Next edit resolve.conf file by opening it with a text editor such as nano or vi:

# vi /etc/resolv.conf

  

nameserver 8.8.8.8 # Replace with your nameserver ip
nameserver 4.4.4.4 # Replace with your nameserver ip

 

Once you have made your changes restart the networking with:

# /etc/init.d/network restart  [On SysVinit]
# systemctl restart network    [On SystemD]

 

Set Static IP Address in Debian / Ubuntu

 

To setup static IP address in Debian/ Ubuntu, open the following file:

# nano /etc/network/interfaces

 

You may see a line looking like this:

auto eth0
iface eth0 inet dhcp

 

Change it so it looks like this:

auto eth0
iface eth0 inet static 
address 15.84.25.84
netmask 255.255.255.0
gateway 15.84.25.83
dns-nameservers 4.4.4.4
dns-nameservers 8.8.8.8

 

Save the file and then edit /etc/resolv.conf like this:

# nano /etc/resolv.conf

 

nameserver 8.8.8.8 # Replace with your nameserver ip
nameserver 4.4.4.4 # Replace with your nameserver ip

 

Restart the networking on your system with:

# /etc/init.d/network restart  [On SysVinit]
# systemctl restart network    [On SystemD]

 

Your static IP address has been configured.
