Hi!
No, no CDN/Cloudflare here...
Some of the entries it complain about do not actually exist, they are handled by a wildcard DNS CNAME...
In one of my examples above:
<<
Old DNS records: blog1.example.com points to example.com
New DNS records: http://www.example.com points to example.com
>>
only http://www.example.com actually exists, blog1.example.com is actually handled by *.example.com...
They are comparing together records which should not be compared, http://www.example.com and *.example.com...
Thank you and have a nice day!
Nick
