I had a bit of an issue with Go Daddy yesterday in that they took 5 days to approve a Subject Alternative Name change to a certificate, and as the usual route of adding a file to a website was unavailable to me I decided to prove ownership of the domain by the addition of a new TXT record to the domain.
Go Daddy’s instructions for doing this are only suitable for domains hosted at Go Daddy and there are no clear instructions for doing this if you do not use Go Daddy for your DNS hosting.
So how do you create an SSL approval with TXT record? You do it by creating a TXT record for a subzone. The subzone is DZC and the value of the record is the seven character string that Go Daddy sent you via email. For example dzc.domain.co.uk TXT AbCdEfG.
Once DNS has replicated to ALL of your DNS servers you can return to Go Daddy’s web form and approve your SSL certificate. You can check if all your DNS servers have your new data by using NSLookup or Dig, but preferred is the use of either of these two tools from an independent third party on the internet – for example www.kloth.net/services/nslookup.php or www.dnssy.com/lookup.php.
