Google, Cloudflare and Quad9 offer public IPv6 DNS servers; their address pairs are listed below. Your connection needs working IPv6 to reach these servers. A DNS change helps your device look up website addresses, but it does not add IPv6 service or increase your broadband plan’s speed.

These are selected services, not a complete worldwide list. Check which version of the DNS service you want using Google’s setup guide, Cloudflare’s address list and Quad9’s service table. Other versions of Quad9’s service have different filtering and privacy features.
What are the Google DNS IPv6 addresses?
Use 2001:4860:4860::8888 and 2001:4860:4860::8844. These are Google’s public IPv6 resolver addresses. The familiar 8.8.8.8 and 8.8.4.4 addresses are the IPv4 pair.
If a router cannot accept the shortened IPv6 form, Google also documents 2001:4860:4860:0:0:0:0:8888 and 2001:4860:4860:0:0:0:0:8844. The double colon is simply a shorter way of writing groups of zeros.
Which IPv6 DNS service should you choose?
Start with the feature you need. Google’s service and Cloudflare’s standard pair provide general lookups. Quad9 Secure adds threat blocking; Cloudflare has separate filtering pairs. Use both addresses from the same intended service if you want its filtering to apply consistently.
No single provider is the fastest on every network. Try ordinary browsing after a change and keep the old or automatic settings so you can switch back.
Does IPv6 DNS only find IPv6 websites?
The address you contact is the resolver’s network address. The answer can contain an IPv4 A record, an IPv6 AAAA record or both, regardless of whether the query reached the resolver over IPv4 or IPv6. Google’s Public DNS FAQ describes IPv6 support.
Change settings carefully
- Record the current settings or confirm they are automatic.
- Check that the network provides usable IPv6 connectivity.
- Use a matching preferred/alternate pair for the service you intend.
- Change DNS in the operating system or router’s supported interface.
- Test ordinary browsing and restore automatic settings if resolution stops working.
Do you need to disable IPv4 DNS?
No. A network that supports both IPv4 and IPv6 can use either to contact a reachable resolver. Do not disable a working protocol just to copy an IPv6 address from a guide. If your connection has no usable IPv6 route, keep the automatic settings or use a supported IPv4 resolver instead.
What a DNS change will not fix
A new resolver cannot repair weak Wi-Fi, a disconnected broadband line or missing IPv6 routing. DNS filtering also does not block every harmful page or replace device security. A provider’s public address alone does not encrypt DNS; set up supported DNS over HTTPS or TLS separately if you need encrypted DNS.
On managed networks, use the approved resolver so internal names continue to work. For raw speed problems, use controlled connection tests before blaming DNS.
Frequently asked questions
What are Google’s IPv6 DNS addresses?
Use 2001:4860:4860::8888 and 2001:4860:4860::8844 on a network with working IPv6 connectivity.
Must I disable IPv4 to use IPv6 DNS?
No. Keep a working dual-stack configuration unless your network administrator requires something else.
Will these addresses encrypt my DNS queries?
The address alone does not enable encryption. Supported DNS over HTTPS or TLS requires separate configuration.
Will changing DNS increase my broadband speed?
It may affect name lookups. It does not increase the line speed or fix weak Wi-Fi.
