Hi everyone

Thanks for all the advice on buying a domain. Its a big week for me. Getting on grapheneos, buying a domain, and I also recently started self hosting my contacts and calendar. I love this way of life.

My original plan was to one of the xyz 1.1111b domains for $1 a year but most of the feedback I got said just go with cloudflare. Its a lot more money than I had planned but all the security features are baked in and I feel that's worth the extra money.

Here are my questions. I use the latest version of truenas community

  1. How do I connect my domain to my server apps? I've got a series of apps I'd love to he able to access without tailscale and solely use the domain.
  2. I have heard the term DNS a million times but don't really understand it. What do.I need to know about DNS to keep security up and stay protected
  3. I'd like to let family access my media server, are there any considerations I need to make?
  4. How can I use one domain to access multiple services on my server? Do I need to pay extra for subdomains?

Thank you for any advice

I have heard the term DNS a million times but don't really understand it.

Learn about DNS, it's the glue that holds the internet together, any time you spend on learning more about DNS will quickly pay off. You probably already know that it's what maps domain names to IP addresses and vice versa, but it can be used for loads of other useful things too.

(My own two favourite not well known but totally standardized really convenient things to use DNS for is to provide SSH host key fingerprints through DNSSEC and requesting letsencrypt certificates for host names without any webserver.)
