I have one purely for a spam email address that I rarely check. I just needed to get off of big brother Google's platforms and I wanted something easy to say and type.
What dream? A domain's quite practical for self-hosting one's own server for all sorts of things. Doesn't have to be the "next big thing". This is the way the internet used to be.
Right? A little script auto to update your DNS records assuming you don't have a static IP, now you can remote in much easier. And don't have to memorize your IP.
And you don’t even have to write the script yourself. Depending on your DNS provider, you can probably use https://github.com/qdm12/ddns-updater or something similar to keep it updated.
I personally use it hosted in Docker with Cloudflare on their free plan and it works great. I tried to set it up with Namecheap initially but they have some requirements for API access, some of which include an allowlisted IP address for API clients. I didn’t want to source, configure, and rely on a static IP jump server just for DNS updates, so I changed the DNS provider (but didn’t transfer the domains).
I've been meaning to get one to use as a fixed email, even if I change the underlying email provider. Not able to select a domain name though ¯\_(ツ)_/¯ naming is always the hardest part
12 dollars? Just buy a .site doman from namecheep for $2 instead. You are guarantied to afford 6 times the normal level of hopes and dreams that way (/s for the second half, but this is what I do for my site)
