Setting alias for DynDNS domain

a-recordcname-recorddomain-name-systemdyndnsns-record

I've created DynDNS domain for testing my local sites, and i'm having trouble with pointing to root domain.

From my registrar (GoDaddy) I've created a CNAME for www to point my example.dyndns.com

so going to url www.example.com I'm reaching my site.

But if I'm going to example.com I'm reaching to the IP of the A record. I can't set the IP for the A record to be my IP because I have dynamic IP, and it changes constatly, and I can't point the A record to domain, only IP.

When trying to create CNAME record @ to point example.dyndns.com I'm getting error "A record of a different type exists for the hostname @, could not create CNAME"

The only record using the '@' host are NS record, which I can't delete, and when tried to set another NS record with @ point to example.dyndns.com, I've lost connection to my site 🙂

So what can I do to get example.com url reach my site?

Thanx!

What's the point of registering a domain with DynDNS if you're not going to use their dynamic DNS service? What you're trying to do is possible by moving your name servers to DynDNS.

IPv6 AAAA vs. CNAME for same domain name

I copy from DNS for Rocket Scientists:

CNAME RRs cannot have any other RRs with the same name, for example, a TXT - well that was true until DNSSEC came along and in this case RRSIG, NSEC and certain KEY RRs can now occupy the same name.

Therefore what you want to do cannot be done using a CNAME. Use the CNAME to access your homesite via IPv4 and have a myhomesite-v6 AAAA record point to the IPv6 address

If you do not want such a solution, you have to implement a mechanism that updates your DNS zone each time your IP address changes with:

myhomesite IN A IPv4.add.ress
           IN AAAA IPv6.add.ress

But that depends on the API (if any) that your DNS provider exports to you. For example if I had root access on the DNS server, I would periodically host -t a example.dyndns.org and use the output to update the zonefile with the IPv4 address for myhomesite.

Godaddy hosting with dynamic ip

My suggestion would be to move your name servers to DynDNS, set up your DNS records there, and install one of their dynamic DNS clients somewhere on your local network to keep your dynamic ip address in sync with your DNS records. I use DynDNS and host 6 web sites at home using their dynamic DNS client.
