# Custom domains

Open a link, album or site on your own domain, such as docs.yoursite.com, with automatic SSL. Free on every plan.

With a custom domain, a link, album or site opens on an address you own, like `docs.yoursite.com`, instead of a Link in Seconds address. Visitors see your domain, and the SSL certificate (the padlock) is set up for you. Custom domains are free on every plan, and you can connect up to 5 of them.

## Before you start

- A domain you own, and access to its DNS settings at your registrar or DNS provider.

- At least one link, album or site to point it at.

## Connect a domain

- ### Open Custom domains Click **Custom domains** in the dashboard sidebar. Or, from a link, open **Link settings**, go to the **Sharing** tab and click **Set up custom domain**. That way the link is already picked for you.

- ### Enter your domain Type it in the **Your domain** field, for example `docs.yoursite.com`.

- ### Pick what it opens Under **Opens this link / album / site**, choose the target. You can only pick things you own. If you have many, a search box appears.

- ### Click Connect domain Your domain appears under **Your domains** with a **Pending DNS** badge and the DNS record to add.

The counter at the top of the form shows how many of your 5 domains are in use. You can't use a Link in Seconds or `vercel.app` address, or a domain that is already connected.

## Add the DNS record

Go to the place where you manage your domain's DNS and add the record shown on the page. Each value has a copy button so you can paste it exactly. Which record you need depends on the address:

| Your domain | Type | Name | Value |

| `docs.yoursite.com` | CNAME | `docs` | `cname.vercel-dns.com` |

| `yoursite.com` | A | `@` | `76.76.21.21` |

A subdomain (like `docs.yoursite.com`) uses a CNAME record whose name is the part before your domain. A root domain (like `yoursite.com` or `yoursite.co.uk`) uses an A record. Always copy the record from the page, since it is made for the exact domain you entered.

Use a subdomain if you can

A subdomain like `files.yoursite.com` leaves your main website untouched. Pointing your root domain here means the root opens your link instead of your website.

## Check status and go live

DNS changes usually take a few minutes, sometimes longer. When you've added the record, click **Check status** on the domain:

- "Your domain is live." The badge changes to **Live** and the domain opens your link.

- "DNS not detected yet, give it a few minutes." The record isn't visible yet. Wait and try again.

- "Couldn't check the domain right now." Our check failed, not your DNS. Try again in a moment.

SSL is automatic. Once the domain points here, the certificate is set up for you, so the address works with `https://`. There is nothing to buy or upload.

## How it behaves

### Your link settings still apply

A custom domain is another way into the same link. Password, expiry date, view limit and the other [link settings](https://linkinseconds.com/docs/link-settings) work the same on your domain.

### Tied to the link, not its name

The domain is bound to the link, album or site itself. If you later change the link's name with **Custom link**, your domain keeps opening it.

### Replace the file any time

Replace the file behind the link and your domain opens the new version. See [Replace a file and keep the link](https://linkinseconds.com/docs/replace-a-file).

## Disconnect a domain

Click **Disconnect** on the domain and confirm. The domain stops opening your link, and its slot is freed. You can then remove the DNS record at your registrar. If the disconnect can't finish, you see an error and the domain stays listed, so try again in a moment.

Want to point it somewhere else?

There is no edit button for the target. Disconnect the domain, then connect it again and pick the new link, album or site.
