# Dynadot CNAME and A record setup (https://dodomain.io/docs/guides/dns-providers/dynadot)

How to add a CNAME, A or TXT record at Dynadot: the host for a subdomain and the root domain (leave it blank), and how to check it's live.

{/* GENERATED by apps/docs/scripts/generate-dns-provider-guides.mts from packages/core/src/guides.ts — do not edit. Change the guide in core, run `pnpm --filter @dodomain/docs generate:dns-provider-guides`, commit both. scripts/check-dns-provider-guides.sh fails the build on drift. */}

These are the steps DoDomain's hosted connect flow shows a customer whose domain is managed at Dynadot, in Dynadot's own vocabulary. A product using DoDomain never writes them: [the connect flow](https://dodomain.io/docs/connect-flow) detects the provider, shows these steps beside the exact records to create, and verifies each record against the zone's authoritative nameservers. They are published here for your own support articles, and for anyone who wants to see the steps before they start.

## Where the records live [#where-the-records-live]

Open [Dynadot's DNS management](https://www.dynadot.com/account/) and pick the domain.

## How to add a CNAME or A record in Dynadot [#how-to-add-a-cname-or-a-record-in-dynadot]

1. Sign in to Dynadot → My Domains → Manage Domains.
2. Tick your domain, click Action, and choose DNS Settings.
3. Pick Dynadot DNS in the drop-down at the top of the page.
4. Add each record below: in Domain Record for the root domain, in Subdomain Records for a prefix such as `www`.
5. Click Save Settings, then come back and click Verify.

## What to put in the Dynadot host field [#what-to-put-in-the-dynadot-host-field]

Enter the subdomain prefix only (e.g. `www`) in Subdomain Records; the root domain goes in the Domain Record section, where you never type the `@` symbol itself. For a record on the domain itself, leave the host field blank.

Whatever the panel calls the field — Name, Host, Hostname — DoDomain's connect flow shows the value to paste into it already in this provider's format, and shows the fully-qualified name it will verify next to it.

## Worth knowing [#worth-knowing]

* These screens apply only while the domain uses Dynadot DNS; with third-party name servers the records go to that provider.
* Dynadot says name server changes can take some time to propagate.

## Common questions [#common-questions]

### Where do I add DNS records at Dynadot? [#where-do-i-add-dns-records-at-dynadot]

Open [Dynadot's DNS management](https://www.dynadot.com/account/) and pick the domain.

### What goes in the host field at Dynadot? [#what-goes-in-the-host-field-at-dynadot]

Enter the subdomain prefix only (e.g. `www`) in Subdomain Records; the root domain goes in the Domain Record section, where you never type the `@` symbol itself. For a record on the domain itself, leave the host field blank.

### How do I check that a record at Dynadot is live? [#how-do-i-check-that-a-record-at-dynadot-is-live]

Look the name up with the free [DNS lookup](https://dodomain.io/tools/dns-lookup), which shows the authoritative answer next to what public resolvers return. DoDomain verifies against the authoritative nameservers, so a record can be correct there while resolvers still serve the old answer until its TTL expires.

## Check the record is live [#check-the-record-is-live]

A saved record is not yet a live record. DoDomain verifies against the zone's **authoritative** nameservers, which answer as soon as the provider publishes the change; public resolvers can lag behind for as long as the old answer's TTL. The free [DNS lookup](https://dodomain.io/tools/dns-lookup) shows both answers side by side for any name, and the [provider detector](https://dodomain.io/tools/provider-detector) tells you which provider serves a domain and whether a one-click path exists for it.

## If you are the product asking for this record [#if-you-are-the-product-asking-for-this-record]

You do not have to send customers here. Mint a connect session and the hosted flow shows these steps to your Dynadot customers on its own, then verifies and keeps monitoring the records — see [the connect flow](https://dodomain.io/docs/connect-flow) and the framework guides for [Next.js](https://dodomain.io/docs/guides/custom-domains-multi-tenant-nextjs), [Rails](https://dodomain.io/docs/guides/custom-domains-multi-tenant-rails), [Laravel](https://dodomain.io/docs/guides/custom-domains-multi-tenant-laravel) and [Django](https://dodomain.io/docs/guides/custom-domains-multi-tenant-django). A customer who wants their bare domain rather than a subdomain is the [apex question](https://dodomain.io/docs/apex-domains), which no provider panel solves on its own.
