Using tinydns wildcards with cautions
Tinydns support wildcards. However I just made a mistake make my own website inaccessible.
I was pointing all subdomains to a single host including this website.
C*.mudy.info:nw.mudy.info:1200
It worked perfect fine, until today I encounter a website which requires myn...@blog.mudy.info to verify ownership. I know it should just working without any further settings, however to be nice I added an additional mx record to my Tinydns to explicitly indicates the mail host of blog.mudy.info
@blog.mudy.info::nw.mudy.info.:5:1200
After that my website become inaccessible. Apparently tinydns will stop looking into data once a matching name found, even though the record type does not match and there are better matching wildcards.
To fix this, I added another explicit A record.
+blog.mudy.info:66.246.138.44:1200
CNAME record will work as well.
