Hello,
one user asked for having uppercase domaine name in the dns plugin.
Not sure its a good idea but we should look what the rfc and bind say on this matter

Activity
So as requested.
" Note that while upper and lower case letters are allowed in domain names, no significance is attached to the case. That is, two names with the same spelling but different case are to be treated as if identical. " from: [[https://tools.ietf.org/html/rfc1035]]
So yes the patch "could" be applied. But the RFC say that Google.com and GOOGLE.com and google.com are the same, so why only accept google.com? (yes, i know.. because the patch is simple :-p)
But that don't remove the other bug, in the system plugins/dns record (first screenshot). Or you need to adapt this patch for the system plugins too, to not accept lowercase for workstation/server/etc...
And the RFC1034 say: [[https://www.ietf.org/rfc/rfc1034.txt]]
" By convention, domain names can be stored with arbitrary case, but domain name comparisons for all present domain functions are done in a case-insensitive manner, assuming an ASCII character set, and a high order zero bit. This means that you are free to create a node with label "A" or a node with label "a", but not both as brothers; you could refer to either using "a" or "A". When you receive a domain name or label, you should preserve its case. "
Regards.
