Alt DCV checker
Checks the domain-control-validation records certificate authorities look for: a DNS TXT record, a DNS CNAME, or a file served over HTTP.
What is Alt DCV checker?
Certificate authorities validate that you actually control a domain before issuing a certificate for it, usually via a DNS TXT record, a DNS CNAME, or a file served over HTTP — this checks whether any of those three methods are correctly set up.
How to use it
Enter a domain, choose a validation method, and optionally the exact value you expect to find — the tool checks live and reports whether it matches.
Example
Checking DNS TXT for a domain might return the record found,
with a match/no-match result if an expected value was given.
