Google Public DNS IP addresses

The 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

Detailed Solution (Step by step) for Windows computer and Mac OS

Change DNS in Windows 10

DNS settings are specified in the TCP/IP Properties window for the selected network connection.

Example: Changing DNS server settings on Windows 10

1. Go to the Control Panel.
2. Click Network and Internet > Network and Sharing Center > Change adapter settings.
3. Select the connection for which you want to configure Google Public DNS. For example:
   • To change the settings for an Ethernet connection, right-click the Ethernet interface and select Properties.
   • To change the settings for a wireless connection, right-click the Wi-Fi interface and select Properties.If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
4. Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties.
5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
6. Click OK.
7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
8. Replace those addresses with the IP addresses of the Google DNS servers:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point.
9. Test that your setup is working correctly; see Test your new settings.
10. Repeat the procedure for additional network connections you want to change.

Note: There is no support for DNS-over-TLS in the base OS. To use DNS-over-TLS requires setting up a proxy resolver that supports DNS-over-TLS. Due to the complexity of the setup we do not describe it here.

macOS

DNS settings are specified in the Network window.

Example: Changing DNS server settings on macOS 10.15

1. Click Apple menu > System Preferences > Network.
2. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password.
3. Select the connection for which you want to configure Google Public DNS. For example:
   • To change the settings for a Wi-Fi connection, select Wi-Fi, and click Advanced.
   • To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced.
4. Select the DNS tab.
5. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point.
6. Click OK > Apply.
7. Test that your setup is working correctly; see Test your new settings.
8. Repeat the procedure for additional network connections you want to change.

Note: There is no support for DNS-over-TLS in the base OS. To use DNS-over-TLS requires setting up a proxy resolver that supports DNS-over-TLS. Due to the complexity of the setup, we do not describe it here.

Linux OS

In most modern Linux distributions, DNS settings are configured through Network Manager.

Example: Changing DNS server settings on Ubuntu

1. Click System > Preferences > Network Connections.
2. Select the connection for which you want to configure Google Public DNS. For example:
   • To change the settings for an Ethernet connection, select the Wired tab, then select your network interface in the list. It is usually called eth0.
   • To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network.
3. Click Edit, and in the window that appears, select the IPv4 Settings or IPv6 Settings tab.
4. If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it.
5. In the DNS servers field, enter the Google Public DNS IP addresses, separated by a comma:
   • For IPv4: 8.8.8.8 and/or 8.8.4.4.
   • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
   • For IPv6-only: you can use Google Public DNS64 instead of the IPv6 addresses in the previous point.
6. Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation.
7. Test that your setup is working correctly; see Test your new settings.
8. Repeat the procedure for additional network connections you want to change.

If your distribution doesn’t use Network Manager, your DNS settings are specified in /etc/resolv.conf.

Example: Changing DNS server settings on a Debian server

1. Edit /etc/resolv.conf:sudo vi /etc/resolv.conf
2. If any nameserver lines appear, write down the IP addresses for future reference.
3. Replace the nameserver 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.
4. Save and exit.
5. Restart any Internet clients you are using.
6. Test that your setup is working correctly; see Test your new settings.
