Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

I have my domain with Cloudflare too, and at this point, I’m not aware of these DNS servers. Can someone explain it a bit? I know what DNS is, but I don’t understand what’s the use case for having them elsewhere. I’m not to argue, just didn’t know where to register a domain, so I went with them. I’m concerned with the future of the domain either, but don’t understand the issues at this early point.
Here is a somewhat simplified explanation
When you are registering a domain you are essentially just creating a NS record:
mydomain.com NS
Then when a resolver is asked a question like what is the A record for myserver.com it goes and asks the tld server (.com) what is the NS record for mydomain.com. the tld then responds with the nameserver ip. Then the resolver will query the nameserver directly for the A record of mydomain.com
In practice there is a ton of caching going on here, but that's the broad strokes
Thanks! I haven’t thought of com as being the real TLD, actually!
The DNS authoratative servers are what hold all of the records for your domain. With Cloudflare, you are stuck with theirs. As for why you want to use a different one, maybe you need more than the 200 records Cloudflare limits you to. Maybe you don't like the way their API works for automating updates. Maybe you don't want to set up all of your records all over again if you transfer your domain to another registrar. Maybe you just don't like Cloudflare.
Thanks! It’s a bit more clear now.
To contribute to the discussion, I remembered that with Squarespace (my previous registrar), I had unlimited redirects, which I used heavily. I am not really sure about the unlimited part, perhaps that was hidden somewhere in the interface, and they have limits, and I just never saw them. But I remember Cloudflare communicated I have like 10, so I decided to not use it for nice-to-have but not really needed things. E.g. I used a subdomain for a blog, and created redirects for typical misprints in my name. Was handy, but not really needed. I should have document this, but I was too busy at the time, and now, almost a year later, I don’t really remember. There were differences with Cloudflare and Squarespace.
