Hi everyone
I posted here awhile ago about something similar but wanted to ask a follow up question.
If I got a 1.111b class xyz domain for my NAS, would that have any issues?
Its mainly just going to be so family and friends can access my jellyfin.
I saw its ten bucks for ten years on their site so its a great price. I’d rather than than 20 bucks a year.
Thank you


I would not expect any issues.
From the point of view of DNS, a name is a name.
You can never tell what weird restrictions any given software is going to place on you (there were a lot of forms that did not like TLD with more than 4 characters, 20 years ago or so). But it’s only $1, so worth experimenting, IMHO.
Please let us know if there are problems!
This is definitely one of those things I didn’t know that I didn’t know. What kinds of restrictions are there on domains, generally? I thought I could just get the cheapest domain that somewhat resembles the name I was going for. I’m not in the market for a domain yet, but I suspect I will be in a few months.
There used to be restrictions on a hostname.
These had to start with and end with a letter or number, and have only letters, numbers, or a dash. (I heard that originally hostnames had to start with a letter, but 3M got that changed. This might be an urban legend.)
That’s a common restriction for a name still.
Things get funky when you want non-ASCII names - like if you want a cyrillic or Greek name - as registries often limit the allowed characters to limit “isomorphic attacks”. That’s where you use symbols that look the same to trick people into thinking they’re going to another site, like using a 0 instead of an O, or a l instead of an I.
None of this will apply to the XYZ domains that give you a number.
One other issue that might impact you is if you try to connect using only a numeric name. Some tools will interpret such a name as an IPv4 address. Easily solved by using the full name, but weird and confusing if it happens to you unexpectedly. 😅
Thanks. Yeah, some of the ones I was targeting were cheap domains like ampersandrew.xyz or whatever. I don’t think I’d be doing anything so fancy as to violate the above. What does the OP’s “1.111b class” mean?
There’s a bit about those on the Wikipedia:

Self reply as a follow up.
I use nom.es for DNS experimentation. These are like $3 a year or so, and work fine.
I miss DotTK, which was dodgy and didn’t support DNSSEC, but was actually free. 😅
