Hello!, thank you for this PR.

can you give me some DNS to check what it does?

thank you!

Sure! .snowflakecomputing.com is a good example.

The previous version would correctly identify A record wildcards, but sadly not CNAME wildcards - but was using existence of a CNAME record to indicate a real discovery, thus leading to false positives

Great tool, thanks for building this!
