Find public DNS IPv4 addresses for Cloudflare, Google Public DNS and Quad9, verified against provider documentation.
Static address directory. Connectivity, resolution speed and access from your network are not checked.
Only six IPv4 endpoints documented by Cloudflare, Google Public DNS and Quad9 are listed. Documentation checked 2026-09-29; network reachability, speed and privacy performance were not tested.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
DNS is the naming system that lets a device look up information associated with a domain name. A DNS resolver receives a query from a device or network and returns a DNS response. A public resolver is one an operator makes available for users to configure instead of, or alongside, the resolver supplied by a network. The addresses below are IPv4 resolver endpoints, not website addresses and not the IP addresses returned for a particular domain.
| Provider | IPv4 address |
|---|---|
| Cloudflare DNS | 1.1.1.1 |
| Cloudflare DNS | 1.0.0.1 |
| Google Public DNS | 8.8.8.8 |
| Google Public DNS | 8.8.4.4 |
| Quad9 | 9.9.9.9 |
| Quad9 | 149.112.112.112 |
Each address is listed as both the start and end of its own record. This is an individual address listing, not a claim that the values form a larger address range. The entries were checked against provider documentation on September 29, 2026. DNS concepts such as names, name servers and queries are described in RFC 1034.

Guide
Follow the workflow and verify inputs and outputs with practical examples.
Enter an address such as 8.8.8.8, or a provider name such as Cloudflare, Google Public DNS or Quad9. Search narrows the displayed records; it does not send a DNS query.
Read across the matching row to confirm the IPv4 address belongs to the provider you intended. The documentation source identifies the provider reference used for the entry.
Select a column heading to sort the visible records by that field. Use the page controls to move through the displayed list when needed.
Use cases
See how the tool fits into real work and everyday tasks.
A network administrator can look up a documented resolver address while preparing a device or router configuration, then confirm the intended service profile in the provider's own documentation.
A home user can search an address found in setup instructions and verify which provider's record it matches before entering it in a device's IPv4 DNS setting.
Q&A
Find concise answers to common questions and confusing cases.
No. The directory is a static reference and does not test whether an address can be reached or answer queries from your network.
For these entries the start and end values are identical because each row represents one address. They do not describe a block of addresses between two different endpoints.
No. This page lists six IPv4 addresses only. Check the relevant provider's documentation for its IPv6 addresses or other connection methods.
Notes
Review scope, result limitations, and important precautions before use.
This is a small reference to six IPv4 addresses documented by Cloudflare, Google Public DNS and Quad9, not a complete catalog of public DNS services. The directory does not report geographic location, latency, uptime, current reachability, filtering comparisons or a privacy ranking. A provider's service options and documentation can change, so verify important configuration details with that provider.
An address appearing here is not proof that it will work on your particular device, network or in your location. It also does not show what DNS policy your employer or internet provider requires. Before changing a managed network setting, follow your administrator's instructions and keep a note of the previous value so you can restore it if necessary.
