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

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 64:ff9b::/96 prefix, you can use Google Public DNS64 instead of Google Public DNS IPv6 addresses, providing connectivity to IPv4-only services without any other configuration.

Some devices use separate fields for all eight parts of IPv6 addresses and cannot accept the :: IPv6 abbreviation syntax. For such fields enter:

• 2001:4860:4860:0:0:0:0:8888

• 2001:4860:4860:0:0:0:0:8844

Expand the 0 entries to 0000 if four hex digits are required.
