To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network. If the method is set to something else, do not change it. Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation.
Replace the nameserver lines with, or add, the following lines: For IPv4: nameserver 8. Save and exit. Restart any Internet clients you are using. Replace that line with, or add, the following line: For IPv4: prepend domain-name-servers 8. For example: To change the settings for an Ethernet connection, click on the Ethernet section.
To change the settings for a wireless connection, click on the Wi-Fi section and select the appropriate network name. Changing the DNS settings for a mobile data connection established with Instant Tethering isn't possible.
For mobile Wi-Fi hotspots that are manually set up, however, you can change the DNS settings using the instructions for a wireless connection. Expand the Network section for the selected connection. In the Name servers section: For IPv4: Select the Google name servers button or alternatively, select the Custom name servers button and enter 8.
Click outside the Network section to apply the settings. Routers Every router uses a different user interface for configuring DNS server settings; we provide only the generic procedure. To change your settings on a router: In your browser, enter the IP address of your router to view the router's administration console.
Most routers are manufactured to use a default address such as When prompted, enter the password to edit network settings. Find the screen in which DNS server settings are specified. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference. Restart your browser. For such fields enter: Expand the 0 entries to if four hex digits are required.
Tap Manual and add Google IP addresses. Optionally you can also remove all default DNS servers in the list. For IPv4: 8. Select Private DNS provider hostname.
Enter dns. Click Save. Beware though, because you must have a basic understanding of how this works to avoid configuration errors. A domain name system handles the process where host names are mapped to IP addresses through a network service called a domain name server.
Each network device, such as a computer, printer or server, has a host name or alias that needs to be assigned a number for communication. To be connected online, a host name has to be mapped to an IP address. This is the primary way you can type in a domain name and be able to connect with that specific system rather than trying to remember a numerical address.
The preferred DNS is a specified primary choice to handle Internet protocol mapping. If the preferred choice times out after a time limit defined by an operating system, it will then attempt to try the alternate DNS. DNS Jumper can be useful, in particular because it's checking how servers perform from your location, but it doesn't run enough tests over a long enough period to give you a definitive answer. This gives a very good general idea of performance, and also enables seeing how services compare on different continents, as well as assessing their uptime.
The steps involved in changing your DNS service vary according to your hardware and possibly your operating system version. Generally, you must start by finding the primary and secondary nameservers for the DNS service you'd like to use.
These IP addresses are normally displayed very clearly on the service website, so, for example, Cloudflare DNS uses 1. The simplest approach for home users is to update their router to use the new addresses. Most other devices will then pick up the new DNS settings automatically, with no further work required.
To make this happen you must log in to your router the default password may be printed on its base and look for the current DNS primary and secondary nameservers. Make a note of the current values in case of problems, then replace them with the nameservers you'd like to use. If you run into problems, check out your DNS service website for any setup guidance. Keep in mind that you can also use the tutorials of other DNS providers, as long as you remember to replace their nameserver IPs with your preferred options.
OpenDNS, for instance, has specific guidance for many different router types on its support site. If router tweaks aren't right for your situation, you may have to change the DNS configuration of each individual device. Cloudflare has short and simple guidance here , while the OpenDNS website goes into more depth.
If you're troubleshooting your internet connection, or maybe thinking of switching DNS servers, it might be useful to check which DNS servers you're using at the moment. After that, life gets more complicated as there are several potential options. Your device could be set up to use specific DNS servers; it might ask your router to give it the best DNS servers every time it boots; or it might not know anything about DNS servers, and leave your router to handle everything.
Look for your network adapter and you should see its DNS servers specified in the list. Enter that IP address into your browser, log in to the router if necessary and your DNS servers should be listed amongst the settings. Granted, not everyone wants to pay and depending on their needs they might not need to, but paid DNS is always a better choice.
Apart from the increased website performance and security, you also get additional features. The Dynamic DNS works with dynamic IP addresses and it allows users to access their home computer from anywhere in the world.
The Secondary DNS works as a backup of sorts which is always a plus. This is just a small fraction of what a premium DNS can do and the exact number of features will depend on the service provider. If your browser is telling you a website's 'server IP address could not be found', even though you're sure it's up and available, then this could be due to a problem with your DNS.
But you might not want to go to the trouble of changing your DNS service to find out. Windows users can use the command line tool nslookup. Then press Enter replace website. If it tells you it 'can't find website. The 8. If nslookup returns errors using multiple servers, this doesn't look like a DNS issue.
