### Domain Name
> 🔔 Discourse will not work from an IP address, you must own a domain name such as `example.com` to proceed.
- Already own a domain name? Great. Select a subdomain such as `discourse.example.com` or `talk.example.com` or `forum.example.com` for your Discourse instance.

We can [recommend NameCheap](https://www.namecheap.com/domains/domain-name-search.aspx?utm_source=SAS&utm_medium=Affiliate&utm_campaign=1632369&affnetwork=sas), or there are many other [great domain name registrars](https://www.google.com/search?q=best+domain+name+registrars) to choose from.
