Nameservers Recursive queries
I have pretty simple DNS configuration, all done via DigitalOcean's web UI.
No playing with any configuration on the server itself, yet www.intoDNS.com reports that I have recursive queries issue:
I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. Problem record(s) are: 184.108.40.206 220.127.116.11 18.104.22.168
Is there anything I've done wrong?
Also, on the root DNS page, I can see both my domains listed, yet only one "PTR Record". Don't know how to add another one.. Should I worry about this PTR?
