How to change and configure DNS in Windows 7 quickly and easily? step by step guide

Do you need to change and configure DNS in Windows 7? Have you heard that this is possible but don’t know how to do it? Pay attention and save this post among your favorites because we are going to tell you about it step by step and we want you to always have it at hand for future reference.

Many people do not know the term DNS and believe that access to some websites or others only has to do with the permissions assigned by their owners. But this is not so, since the DNS of each equipment are created by default by the provider team services but can be modified to avoid certain restrictions, security deficiencies and other difficulties when accessing an IP address.

How does a DNS (Domain Name Server) work? Well, it’s very simple. When we position ourselves in our internet browser and write the address of a web page, our DNS transforms this address into a combination of 4 numbers separated by dots; what is called address IP.

Steps to change the DNS in Windows 7 and configure them correctly

In this section we are going to show the most correct way in which you can configure your DNS without going too crazy and so you can do it whenever the need arises. It is not too complicated and every user can follow those steps at any time even without great computer skills. Let’s see it!:

• First, we must click on the button “Start”.
• From there, we open the “Control Panel”.
• Within this, you should look for the option “Network and Internet”.
• there, choose “Center network and sharing”.
• Now is the time we should click on “Change adapter settings”.
• In this way, we will have to choose between one of the two connections that can be used. In any of them, the device may request an administrator password or some type of confirmation to allow this configuration change to be made.
• On the one hand, we have the connection Ethernet. If it is ours, we must click on “Local Area Connection” with right click and then on the “Properties” option.
• On the other hand, we have the connection wirelesswhere we must select the option that bears the same name with the right button and then click again on the “Properties” button.

• Now you must choose the tab where it says “Networks” and check all the elements of the connection.
• We are going to go specifically to the last element of the list, where you can read “Internet Protocol Version 4 (TCP/IP)”.
• Once the option has been selected, the button must be pressed again. “Properties”.
• Now we select “Advanced”which is at the very end.
• Among all the tabs that appear in the box, we select “DNS”. This is the area where our service provider may have placed some DNS and therefore where we need to work. When changing them, this data can no longer be recovered, so it is vitally important not to lose it, copy them!
• Can modify the addresses that are marked for those of the google dns servers, which, in my opinion, are usually the most complete. However, you can choose from tons of others (now we’ll show you a list, in fact).
  • Primary DNS: 8.8.8.8
  • Alternate DNS: 8.8.4.4
• Now, with Google or any other, click on the button “To accept” for the changes made to take effect.
• You should restart the connection previously selected. We recommend that you carry out this procedure to change all the additional connections you have, although this is not something that should be done on a mandatory basis.

How to fix DNS when not responding in Windows 7?

As you have seen, DNS modification in Windows 7 is not complicated. In fact, by following the steps in the previous section you can do it quickly and without much help.

However, once you’ve done it, it may be that from your connection it is still not possible to access an address specific website.

This It may have to do with some configuration that your antivirus has at intermediate level. Take a few minutes to review it to check that everything works properly and not waste time working with the DNS, which can always be more difficult and cause problems if it is not done well.

There is also the possibility that the rules you have created for your FireWall They may be stopping the connection for something. This in a basic level user does not have to be of any importance because he will not have carried out any particularity, but if it happens to you at the company level, it is probably one of the causes of your problem.

If you have reviewed the two previous points and still do not have access to a site, the time has come to refresh dns settings in windows 7. To be able to do it, we can modify the DNS following the previous steps and including completely different ones, but if you want to keep the ones you have chosen, we will work from the Windows console.

• For this, it is necessary open an executable at the command promptthat is, the console (here we tell you how to do it in different ways).

• Now we must go typing each of the commands of the system to, thus, go executing said refresh:
  • Command to free the DNS cache: ipconfig/flushdns
  • Command to register DNS again: ipconfig/registerdns
  • Command to release IP address: ipconfig/release
  • Command to renew the IP address: ipconfig/renew
  • Command to reset the DNS cocktail: netsh winsock reset
• now you can try reconnect to test the perfect functioning of the created DNS.
