# Custom nameservers

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/nameservers/custom-nameservers/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

With custom (or vanity) nameservers, a domain can use Cloudflare DNS without using Cloudflare-branded nameservers. For instance, you can configure `ns1.example.com` and `ns2.example.com` as nameservers for `example.com`.

To use custom nameservers, a zone must be using Cloudflare as Primary ([Full setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/zone-setups/full-setup/)) or [Secondary](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/zone-setups/zone-transfers/cloudflare-as-secondary/) DNS provider.

## Configuration scope

* [Set up zone custom nameservers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/nameservers/custom-nameservers/zone-custom-nameservers/)
* [Set up account custom nameservers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/nameservers/custom-nameservers/account-custom-nameservers/)
* [Set up tenant custom nameservers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/nameservers/custom-nameservers/tenant-custom-nameservers/)

## Availability

* Zone custom nameservers are available for zones on Business or Enterprise plans. Via API or on the dashboard.
* Account custom nameservers are available for customers on Business (after [contacting Cloudflare Support](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/support/contacting-cloudflare-support/)) or Enterprise plans. Once configured, account custom nameservers can be used by all zones in the account, regardless of the zone plan. Via API or on the dashboard.
* Tenant custom nameservers, if created by the tenant owner, will be available to all zones belonging to any account that is part of the tenant. Via API only.

## Restrictions

Custom nameservers are organized in different sets (`ns_set`). Each namesever set must have at least two and no more than five custom nameserver names.

The advantages that come with Foundation DNS [advanced nameservers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/foundation-dns/advanced-nameservers/) are currently not available for [custom nameservers](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/dns/nameservers/custom-nameservers/). Make sure you only use one at a time.
