Subdomains where nameservers are not changeable.
I have a private domain registered with a UK based company (claranet). On the Domain admin it doesn't let you change the nameservers so I can't point them to DigitalOcean.
I have added an A record so that the global domain works pointed to a test virtual host. I've also added letsencrypt so that the HTTPS works correctly.
I am trying to add subdomains so I can have <subdomain>.mydomain.net or to redirect <www>.domain.net to domain.net but I can't find any information about what the content of the C record should be so that it will work.
