Partial hyphenated wildcard sub domain dns records

Question

What are the correct DNS records for {any}-the-sub.example.com?
While avoiding CNAME *.example.com

For extended subdomain {any}.the-sub.example.com that would be something like:

the-sub.example.com     A       0.0.0.0
*.the-sub.example.com   CNAME   the-sub.example.com

However same doesn't apply when using hyphen {any}-the-sub.example.com. nor the *-the-sub.example.com or *the-sub.example.com wont work right?

@Andrew I beleave you are correct this is duplicate since [accepted answer](http://serverfault.com/a/504937/163684) there does kind of answer my question. — mkungla, Mar 30 '17 at 13:25

Wildcards in DNS only apply to whole labels (labels are the parts of domain names between dots). Nothing in general DNS does what you ask for.

It is possible that some particular DNS server software may have a functionality to auto-generate records according to the sort of rules you describe, but I'm not personally familiar with any.
