# Set Account Custom Nameserver Related Zone Metadata

Deprecated: Use \[DNS settings API](https://developers.cloudflare.com/api/resources/dns/subresources/settings/methods/put/) instead.

zones.custom\_nameservers.update(CustomNameserverUpdateParams\*\*kwargs) -> SyncSinglePage\[[CustomNameserverUpdateResponse](<https://developers.cloudflare.com/api/python/resources/zones#(resource)%20zones.custom_nameservers%20%3E%20(model)%20custom_nameserver_update_response%20%3E%20(schema)>)]

PUT/zones/{zone\_id}/custom\_ns

Set metadata for account-level custom nameservers on a zone.

If you would like new zones in the account to use account custom nameservers by default, use PUT /accounts/:identifier to set the account setting use\_account\_custom\_ns\_by\_default to true.

Deprecated in favor of [Update DNS Settings](https://developers.cloudflare.com/api/operations/dns-settings-for-a-zone-update-dns-settings).
