The DHCP Client ID need to be assigned to both the Wi-Fi and Ethernet connections.

MAC NETWORK SETTINGS STATIC IP MAC

To ensure that the Static IP Address is used, irrespective of whether the device is connected by Wi-Fi or Ethernet use the DCHP Client ID method, in Step 7, in place of the MAC Address method. If you need to be able to connect a device either using Ethernet or Wi-Fi, with the same Static IP address for both types of network connection the method using the MAC Address will not work, because Ethernet and Wi-Fi network interfaces each have unique MAC Address. Use the ‘ifconfig’ command to confirm the IP address has been updated successfully.In the second method, using the AirPort Extreme there are actually two methods of setting up Static IP Address, one with MAC Address described in this article, the other using a DHCP Client ID.

MAC NETWORK SETTINGS STATIC IP PC

Your PC should now retain its IP address across reboots, or even when a DHCP server is not working. Sample output: # /etc/init.d/network restart To activate the changes you will need to reboot the PC, or simply restart networking (recommended). nameserver 192.168.0.1ĭepending on your setup, this could be your router’s IP, your ISP’s DNS server IP, or a 3rd party’s DNS server, such as Google’s (8.8.8.8 and 8.8.4.4), or OpenDNS. If not, add one or more nameserver records in the format below. If one already exists, and is valid, great. You will want at least 1 nameserver set up in this file. You will also need to set up the DNS nameserver settings manually. Once you have finished with the changes to the file, save and quit the editor. The default gateway address can be obtained by using the ‘route’ command. If you are unsure what settings should go in this file, you can always run the ‘ifconfig’ command, which will output the current IP address settings obtained via DHCP (if DHCP is set up). Make sure you change the relevant settings to suit your network. The # character at the beginning of the line indicates that it is commented out, and will be ignored.

This allows you to change it back easily at a later date if you want to.

If you dont want to delete the lines, simply comment them out. Most of the lines in this file will be changing, so your best option is to remove all the lines except the first one, and copy the example format from the example below. You should see the lines similar to the following in the editor. # vi /etc/sysconfig/network-scripts/ifcfg-eth0 Make sure you are logged in as “root”, or a user with root privileges. This guide will be using the “vi” editor, but you can use “nano” or another editor.

Open up the /etc/sysconfig/network-scripts/ifcfg-eth0 file in your favorite editor. This example will assume that you want to set up the static IP address on the first network interface. The files to look for are ifcfg-eth# where # is the network interface number, starting from 0.

The following steps will guide you through setting up your computer to use a static IP address on CentOS.Īssuming the network interface is supported and detected under CentOS, you will find that the configuration files required to set the IP address can be found under /etc/sysconfig/network-scripts.

MAC NETWORK SETTINGS STATIC IP HOW TO

If for whatever reason you dont want to go down the path of setting a DHCP reservation (you may not have access to the DHCP server unsure how to set it up etc), the only option is to set a static IP address on the PC itself. You could set up a IP address reservation on the DHCP server based on the hardware/mac address of the network interface, or alternativly, set the operating system to use a static IP address. There are two options for ensuring you get/use the same IP address at every boot. While that may be fine for most desktop users, if you are wanting to set up a server, the chances are you will be wanting it to always have the same IP address.

MAC NETWORK SETTINGS STATIC IP INSTALL

During a default install of CentOS it will try to either automatically obtain an IP address using DHCP, or it wont even set up the network interface automatically.
