## Connecting a domain to a Serverlet

Any domain can be connected to a Serverlet. Every second-level and third-level domain counts as one separate domain. The `www.` variant of a domain is routed automatically and does not count towards the number of connected domains. It is enough to connect, for example, the domain `mydomain.com`; the `www.mydomain.com` variant will be connected automatically.

Wildcard variants, for example `*.mydomain.com`, cannot be used.

> **Information:** Each domain can be connected to only one Serverlet at a time. If a domain is already connected to another Serverlet, please contact us and we will look into the situation.

You will find the connected domains in the administration on the **Domains** card of that Serverlet.

Once a domain is connected, certificates are generated within hours. We manage and renew them automatically. Certificates are not stored on the Serverlet and are not available to customers; using your own certificates is not possible. Secure transfer over HTTPS (port 443) is handled by the load balancer, which forwards it on to the HTTP port `80` of the Serverlet.

### Setting up DNS records

Connecting the domain to the Serverlet alone is not enough for a website to appear on it. At your current DNS provider you have to add a CNAME record, or A and AAAA records, for every connected domain.

#### CNAME record

For subdomains a CNAME is no problem and we recommend using it. If your DNS provider supports some form of CNAME flattening, we recommend using a CNAME for the main record of the domain as well. Add it as an alias of the physical server domain, which you will find in the administration on the **Overview** card of the Serverlet:

```dns
www.mydomain.com.      IN      CNAME  rumble.futrou.com.
```

#### A/AAAA records

If your DNS provider does not support CNAME flattening, a CNAME cannot be used as the main record of the domain. Set an A record for IPv4 and an AAAA record for IPv6 manually to the IP addresses of the physical server instead:

```dns
www.mydomain.com.      IN      A      159.69.119.71
www.mydomain.com.      IN      AAAA   2a01:4f8:c010:d03::1
```

You can find the specific IP addresses with the `nslookup` command on Windows and the `host` command on Linux, run against the domain of the relevant physical server:

```text
C:\>nslookup rumble.futrou.com
Server:      one.one.one.one
Address:     1.1.1.1

Non-authoritative answer:
Name:        rumble.futrou.com
Addresses:   2a01:4f8:c010:d03::1
             159.69.119.71
```

```bash
host rumble.futrou.com
# rumble.futrou.com has address 159.69.119.71
# rumble.futrou.com has IPv6 address 2a01:4f8:c010:d03::1
```

## Registering domains

You can find a list of cost-effective registrars for individual TLDs at [tldes.com](https://tldes.com/), for example. A number of registrars offer domains without a margin of their own, charging only the fee they pass on to the registry of the given domain.

Recommended options:

- **WEDOS** for ccTLDs, for example `.cz`, `.sk`, and `.eu`.
- **Cloudflare** for gTLDs, for example `.com`, `.org`, `.net`, and `.info`.
- **Namecheap** or **Spaceship** for both gTLDs and ccTLDs.

## What to watch out for when registering a domain

### Checking domain availability

> **Warning:** Never check domain availability on dubious websites. Domain speculators may run them, register the domain you show interest in before you do, and then sell it for a multiple of the price.

Check it directly with a trustworthy registrar or domain registry:

- for `.cz` at [NIC.CZ WHOIS](https://www.nic.cz/whois/),
- for gTLDs such as `.com`, `.org`, and `.net` at [ICANN Lookup](https://lookup.icann.org/),
- for other ccTLDs directly with their registry, for example DENIC for `.de` or DNS.PL for `.pl`.

### Renewal prices

> **Warning:** Some registrars sell the first year below cost and then charge several times more for the renewal. Always check the price for subsequent years before registering.
