Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Add a DNS Resource Record
In this article
Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016 You can use this topic to add one or more new DNS resource records by using the IPAM client console. Membership in Administrators, or equivalent, is the minimum required to perform this procedure. To add a DNS resource record
- In Server Manager, click IPAM. The IPAM client console appears.
- In the navigation pane, in MONITOR AND MANAGE, click DNS Zones. The navigation pane divides into an upper navigation pane and a lower navigation pane.
- In the lower navigation pane, click Forward Lookup. All IPAM-managed DNS Forward Lookup zones are displayed in the display pane search results. Right-click the zone where you want to add a resource record, and then click Add DNS resource record.
- The Add DNS Resource Records dialog box opens. In Resource record properties, click DNS server and select the DNS server where you want to add one or more new resource records. In Configure DNS resource records, click New.
- The dialog box expands to reveal New Resource Record. Click Resource record type.
- The list of resource record types is displayed. Click the resource record type that you want to add.
- In New Resource Record, in Name, type a resource record name. In IP Address, type an IP address, and then select the resource record properties that are appropriate for your deployment. Click Add Resource Record.
- If you do not want to create additional new resource records, click OK. If you want to create additional new resource records, click New.
- The dialog box expands to reveal New Resource Record. Click Resource record type. The list of resource record types is displayed. Click the resource record type that you want to add.
- In New Resource Record, in Name, type a resource record name. In IP Address, type an IP address, and then select the resource record properties that are appropriate for your deployment. Click Add Resource Record.
- If you want to add more resource records, repeat the process for creating records. When you are done creating new resource records, click Apply.
The Add Resource Record dialog box displays a resource records summary while IPAM creates the resource records on the DNS server that you specified. When the records are successfully created, the Status of the record is Success. When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS. In most cases, the Dynamic Host Configuration Protocol (DHCP) automatically configures your system to use the IP addresses of your ISP's domain name servers. To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac, Linux, or ChromeOS) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; consult your vendor documentation for authoritative information. Depending on your system you may also have the option of enabling a new privacy-oriented feature called DNS-over-TLS. This feature provides privacy and security for the DNS messages sent between your device and Google's DNS servers. Details on configuring this optional feature are in specific sections for each system. Important: Before you startBefore you change your DNS settings to use Google Public DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time. We also recommend that you print this page, in the event that you encounter a problem and need to refer to these instructions. Google Public DNS IP addressesThe Google Public DNS IP addresses (IPv4) are as follows:
8.8.8.8
8.8.4.4
The Google Public DNS IPv6 addresses are as follows:
2001:4860:4860::8888
2001:4860:4860::8844
Some devices require explicit values for all eight fields of IPv6 addresses and cannot accept the abbreviated
2001:4860:4860::8888
2001:4860:4860::8844
1 IPv6 address syntax. For such devices enter:
2001:4860:4860:0:0:0:0:8888
2001:4860:4860:0:0:0:0:8844
Expand the
2001:4860:4860::8888
2001:4860:4860::8844
2 entries to
2001:4860:4860::8888
2001:4860:4860::8844
3 if four hexadecimal digits are required. You can use either address as your primary or secondary DNS server. You can configure Google Public DNS addresses for either IPv4 or IPv6 connections, or both. For IPv6-only networks with a NAT64 gateway using the
2001:4860:4860::8888
2001:4860:4860::8844
4 prefix, you can use Google Public DNS64 instead of Google Public DNS IPv6 addresses, providing connectivity to IPv4-only services without any other configuration. Change your DNS servers settingsBecause the instructions differ between different versions/releases of each operating system, we only give one version as an example. If you need specific instructions for your operating system/version, please consult your vendor's documentation. You may also find answers on our user group page. Many systems let you to specify multiple DNS servers, to be contacted in priority order. In the following instructions, we provide steps to specify only the Google Public DNS servers as the primary and secondary servers, to ensure that your setup correctly uses Google Public DNS in all cases. WindowsDNS settings are specified in the TCP/IP Properties window for the selected network connection. Example: Changing DNS server settings on Windows 10 - Go to the Control Panel.
- Click Network and Internet > Network and Sharing Center > Change adapter settings.

2001:4860:4860:0:0:0:0:8888
2001:4860:4860:0:0:0:0:8844 8: sudo vi /etc/resolv.conf
- If any
sudo vi /etc/resolv.conf
0 lines appear, write down the IP addresses for future reference. - Replace the
sudo vi /etc/resolv.conf 0 lines with, or add, the following lines:
For IPv4: nameserver 8.8.8.8
nameserver 8.8.4.4 For IPv6: nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844
For IPv6-only, you can use Google Public DNS64 instead of the above IPv6 addresses. - Save and exit.
- Restart any Internet clients you are using.
- Test that your setup is working correctly; see .
Additionally, if you are using DHCP client software that overwrites the settings in
2001:4860:4860:0:0:0:0:8888
2001:4860:4860:0:0:0:0:8844
8, you need to configure the DHCP client by editing the client's configuration file. Example: Configuring DHCP client software on a Debian server - Back up
2001:4860:4860:0:0:0:0:8888
2001:4860:4860:0:0:0:0:8844 8: sudo cp /etc/resolv.conf /etc/resolv.conf.auto
- Edit
sudo vi /etc/resolv.conf 4 (or sudo vi /etc/resolv.conf 5): sudo vi /etc/dhcp*/dhclient.conf
- If there is a line following
sudo vi /etc/resolv.conf 6 with only sudo vi /etc/resolv.conf
7 remove that line. - If there is a line containing
sudo vi /etc/resolv.conf
8 with IP addresses, write down the IP addresses for future reference. - Replace that line with, or add, the following line:
For IPv4: prepend domain-name-servers 8.8.8.8, 8.8.4.4; For IPv6: prepend domain-name-servers 2001:4860:4860::8888, 2001:4860:4860::8844;
For IPv6-only, you can use Google Public DNS64 instead of the above IPv6 addresses. - Save and exit.

- In the Name servers section:
- Click outside the Network section to apply the settings.
- Test that your setup is working correctly; see .
- Repeat the procedure for additional network connections you want to change.
RoutersEvery router uses a different user interface for configuring DNS server settings; we provide only the generic procedure. For more information, please consult your router documentation. 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
nameserver 8.8.8.8
nameserver 8.8.4.4 3, nameserver 8.8.8.8
nameserver 8.8.4.4 4, nameserver 8.8.8.8
nameserver 8.8.4.4 5, or nameserver 8.8.8.8
nameserver 8.8.4.4
6. If none of these work, try to find the default gateway address in the network settings panel of your system. - 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.
- Replace those addresses with the Google IP addresses:
- Save and exit.
- Restart your browser.
- Test that your setup is working correctly; see .
Some routers require explicit values for all eight fields of IPv6 addresses and cannot accept the abbreviated

3 if four hexadecimal digits are required. iOSYou can change DNS settings on iPhone, iPad, or iPod touch with the following steps. - Go to Settings > Wi-Fi.
- Tap the ⓘ icon next to the Wi-Fi network that you want to change DNS servers for. Scroll down to find the DNS section and tap Configure DNS.
- Tap Manual and add Google IP addresses. Optionally you can also remove all default DNS servers in the list.
Switching back to Automatic will restore the DNS server specified by the Wi-Fi network. Android
Android 9 (Pie) or higherAndroid 9 supports "Private DNS" which uses DNS-over-TLS to provide security and privacy for your DNS queries. You can configure it with the following steps. - Go to Settings > Network & Internet > Advanced > Private DNS.
- Select Private DNS provider hostname.
- Enter
nameserver 2001:4860:4860::8888
nameserver 2001:4860:4860::8844
8 as the hostname of the DNS provider. - Click Save.
For more information see the Android blog post announcing the feature. Please note that in Android P, the default mode for Private DNS is "Automatic" which means it uses the network specified DNS server and it attempts a TLS connection to port 853 before falling back to UDP on port 53. Older Android versionsDevices running versions older than Android 9 do not support DNS-over-TLS and cannot configure private DNS for all networks. You can configure DNS for each individual Wi-Fi network you use. This requires configuring all network information manually and is only recommended for advanced users. Mobile or other devicesDNS servers are typically specified under advanced Wi-Fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only the generic procedure. For more information, please consult your mobile provider's documentation. To change your settings on a mobile device: - Go to the screen in which Wi-Fi settings are specified.
- Find the screen in which DNS server settings are specified.
- If there are IP addresses specified in the fields for the primary and secondary DNS servers, write them down for future reference.
- Replace those addresses with the Google IP addresses:
- Save and exit.
- Test that your setup is working correctly; see .
Test your new settingsTo test that the Google DNS resolver is working: - From your browser, enter a hostname URL (such as
sudo cp /etc/resolv.conf /etc/resolv.conf.auto 3). If it resolves correctly, quit the browser, load the page again and refresh it for several times to make sure the result is not from a cached web page. - From your browser, type in a fixed IP address. You can use
sudo cp /etc/resolv.conf /etc/resolv.conf.auto 5 (which points to the test-ipv6.com website) as the URL. - Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance.
If you encounter any problems after setting Google Public DNS as your resolver, please run the diagnostic procedure. 1 Google thanks Jason Fesler for granting permission to use test-ipv6.com URLs for browser DNS testing purposes. Switch back to your old DNS settingsIf you had not previously configured any customized DNS servers, to switch back to your old settings, in the window in which you specified the Google IP addresses, select the option to enable obtaining DNS server addresses automatically, and/or delete the Google IP addresses. This reverts your settings to using your ISP's default servers. If you need to manually specify any addresses, use the procedures above to specify the old IP addresses. How do I add an IP address to my DNS server?From the Windows desktop, open the Start menu, select Windows Administrative Tools > DNS. Select and hold (or right-click) your server, and then select Properties. To limit the DNS server to use a specific IP address, select Only the following IP address, select the IP address you wish to use, and then select OK. How can I add multiple IP addresses to one DNS a record?Navigate to the DNS management section for the domain name you want to edit. Locate the existing DNS record that you want to add the IP addresses to or create a new record. Add multiple IP addresses to the record by creating additional "A" or "AAAA" records with the same domain name but different IP addresses. What are the servers at the top of the DNS hierarchy?The administration of the Domain Name System (DNS) is structured in a hierarchy using different managed areas or “zones”, with the root zone at the very top of that hierarchy. Root servers are DNS nameservers that operate in the root zone. What is top level DNS IP?In the DNS hierarchy, a top-level domain (TLD) represents the first stop after the root zone. In simpler terms, a TLD is everything that follows the final dot of a domain name. For example, in the domain name 'google.com', '.com' is the TLD. |
