Let’s assume that we have the domain
company.com, our zone file:
$TTL 3600 @ IN SOA dns200.anycast.me. tech.ovh.net. (2018022800 86400 3600 3600000 300) IN NS dns200.anycast.me. IN NS ns200.anycast.me. IN A 18.104.22.168 www IN A 22.214.171.124 nsint IN A 192.168.1.22 inside IN NS nsint.company.com.
As you may see, there all requests for something.inside.company.com go to our inside dns server which works perfectly in our ptivate (non-routable) subnet.
Now I would like to issue LE certificate for
How can I proof that I own the subdomian? Can I do it by proofing that I own the domain company.com ?
I would like to avoid adding public DNS entries just for the 10minutes for verification every 60days…
