If you are an Enterprise customer and require more DNS records, contact your account team. Cloudflare can support millions of DNS records on a single zone.
:::

DNS records that other Cloudflare services create on your behalf — for example, the `TXT` and `MX` records added by [Email Routing](/email-routing/) — also count toward this limit. To avoid disrupting those services, they are enforced against your record limit with a small buffer, so a zone may occasionally hold slightly more records than its limit would otherwise allow.

To create new records yourself through the dashboard or API, your zone must still be within its record limit.

### How long does it take for a DNS change I made to push out?

By default, any changes or additions you make to your Cloudflare zone file will take effect globally within 5 minutes, usually much less.
