Minimum length for subdomains
Is there a problem with using a 1-3 letter for a subdomain?
I currently use , with the same document root.
At the same time, I also created a second short subdomain of

Hey hey! No problem with short subdomains at all, and I would also expect cPanel to create the DNS records properly on the system. It might be worth looking through the /usr/local/cpanel/logs/error_log file to see if there are any entries related to that subdomain creation around that time. 0 -
The only reference I find to " i." or " inc." is on Dec 12 (hopefully none of this is sensitive, I just pasted it and changed the domain to example.com): # Before this is a long series of "info [cpsrvd] version 11.92.0.4 online", and the # line just before this is 15:24:32 (5 minutes prior) so I don't think it's related ==> cpsrvd 11.92.0.4 started ==> cpsrvd: loading security policy....Done ==> cpsrvd: Setting up SSL support ...

That doesn't appear to be an error, though, just a lot of when I created them, maybe? I created A records manually, so we'll see how that goes after they propagate.0 -
If you're able to reproduce the problem with another domain or subdomain it would be interesting to see those logs in real-time. 0 -
Well, I just now created the "i" subdomain on another account, and it's showing up in the DNS. So... cool, I guess? No clue on why it didn't work before. When I set them up last month, I did both "i" and "inc" on a 4-letter domain with both .CO and a .NET extensions while using cPanel v.11.92.0.4. This one was on a longer domain with a .COM extension, using v.11.92.0.6. That's the only differences that I can see. 0 -
I don't have a good explanation for this one - all the testing I just did with one-letter subdomains worked well on my end. 0
