Windows systems. Nslookup how to use the command. How to find out your IP address and DNS server address Basic DNS parameters

Hi all! Domain Name System is translated as domain name system. I will not go into details of the definition and features of functioning. Let me just briefly say that it is used for the correct operation of network connections. Do you know where their parameters are?

Today I’ll tell you how to find out the DNS server for connecting your computer to the global network, interaction between the domain and hosting for the site. In the first and second cases, the addresses are usually different.

What exactly are you interested in?

Working with DNS:

Working with ISP DNS addresses to configure the Internet

Let's take a look at a few options. The DNS name for setting up network connections can be found out in three ways, or rather using:

• command line;
• viewing network properties;
• Internet provider.

The first two ways to view the preferred and alternative DNS gateway are useful only if the network is already working correctly. The third point is suitable even if it does not work.

Using the Command Line

In the first case, in the Start menu you will need to find the “command line” program. Open it and enter the service command ipconfig/all. After its application, sufficiently detailed information will appear.

As you can see in the screenshot, the required data is shown among other results.

View and change connection settings

To implement the second method, you will need to go to the control panel. For XP, then open “network connections”, for Windows 7 - the “change adapter settings” section in the control center for various networks.

After completing these steps, a list of connections should appear before your eyes. We select the one that is usually used and begin viewing its properties.

Found it? Now in the open window you can see fields for entering your preferred and alternative addresses. Here you can view the existing server names for connecting to the provider’s services, if you previously entered them, or set new values. After making changes, you need to save them by confirming the action.

Contacting your Internet provider for help

There are options here too:

• look on the provider’s website if it publishes such data;
• ask the support service;
• call a specialist to your home.

These steps are some of the simplest. There is nothing complicated in their implementation. Go ahead.

DNS address for domain and hosting setup

If they are registered with different service providers, then there is a need for additional manipulations. In particular, you need to find out your NS records on your hosting, then specify them in the domain settings.

If they have not yet been specified, then the only main option is to find out on the electronic resources of the service provider or with the help of support staff. If they have already been set, and you need to view them for your own or someone else’s site, then you can use a special service.

You can generally determine your own or someone else’s DNS for hosting by IP or domain. It's not difficult to do this. This was discussed in detail in a publication about various input data.

Now you know how you can find out the DNS server addresses for a computer or website. Still have questions or know about more convenient options? Just leave a comment.

Introduction to DNS

Domain Name System (aka DNS) stands for “domain name system” and serves to direct Internet users to specific website addresses. That is, enter a familiar address in the browser or go to a site through a saved tab, and at this time your ISP (provider) finds it in the domain name server and redirects your request to the desired site. If you write everything out schematically, it looks like this:

www.name.com => search ns domain => DNS returns the IP address of the site - 255.0.1.19 => the contents of the site are opened.

Domain name servers store information about your website (such as name or IP). Correctly configured DNS domain parameters allow users to access the site. Any error will result in access to the resource being impossible. It's like trying to open a lock with the wrong key.

How changing hosting affects a domain

Hosting is a conditional place for storing information on a server that is always connected to the Internet. It hosts websites and various kinds of resources that receive an IP from the hoster’s database.

When you change hosting, the IP changes accordingly. And as we already know, this is the main address where our resource is found on the Internet. Therefore, with this operation it is necessary to check and register the DNS of the domain.

How to view parameters

To ensure that users do not have problems finding your resource on the Internet, you must correctly specify the DNS for the domain and ensure that the parameters are always correct. The slightest extra sign/symbol will block access to the resource.

There are several ways to find out DNS parameters.

1. If you are the owner of a resource, you can check DNS records in the main menu of the control panel. To do this, enter “http://ip.address/da” into the browser line, where you substitute your IP.
2. If you want to find out the DNS of a resource that is not yours, then you can use third-party services. There are many offers on the Internet today for assessing domain parameters. Through some you can even change NS.

Basic DNS Settings

There are 5 main parameters, called records, that must always be configured. This:

1. A records - Address record - allow you to bind a host name in a domain to the corresponding IP.
2. CNAME - Canonical Name records - allow you to assign aliases. For example: example.ua CNAME domain.ua; example2.ua CNAME domain.ua.
3. Setting up an NS record allows you to contact the DNS server for that domain. Changes to this entry may result in the site not working. If you want to make edits, but don’t know how to change NS records in the settings, then still go to the main menu of the taskbar, and you can make edits in the appropriate section.
4. PTR - pointer records - associate the IP address of the host and the canonical name.
5. MX records - Mail Exchange - allow you to bind mail servers for a domain. There can be several of them with a customizable priority for each. The mail server with the highest priority is the primary one. You can change the digital priority value in the settings.

These are the DNS parameters that need to be touched as little as possible. They sometimes lead to global changes for the site.

Settings and adjustments

And again we will talk about the main menu of the control panel. It was previously described how to get into it (if you are the owner of the domain and have access rights). In this menu, basic operations with the domain are carried out. Changes take effect within 24-72 hours. That is, if you want, for example, to change NS, be prepared for the resource to be unavailable for some time.

This is due to the fact that adjustments to the data are rarely introduced. And the update frequency takes from one to three days.

If you need to register DNS parameters, you must first delete the old ones, add new ones, and be sure to check the parameters after a while. This can be done in the control panel, as well as in services, to evaluate the display of edits and innovations.

If you have questions about how to set parameters, you need help and support from experienced specialists. Contact our service - we will help you set up, edit and post.
