Network Operating Systems-I

notes

The finest part is support for dynamic DNS is included in their DNS offerings so you can use
them for home and test servers that don’t have static IP addresses (and ddclient will work with
them too).

As a side note, what if you previously have a domain name with servers that have static IP
addresses? Most places that will host your DNS records (like your ISP or Web hosting provider)
won’t let you even see them much less work with them. Having EasyDNS host your DNS records
will allow you to have some control in the management of your DNS. Their straight DNS records
hosting service (without the domain registration/renewal piece) costs $20/year. Just be sure to
update your domain record with the EasyDNS name servers information once you sign up for
the service and get your DNS records set up. (You also have the option of transferring your
domain to them, i.e. making them the domain name registrar, if you want to take advantage of
the single-payment convenience thing.)
Having your own non-production domain will not only allow you to play around with zone
records, but you can experiment with having your own authoritative DNS server. One of
EasyDNS’s servers would be the primary authoritative name server and you could set up your
Debian server as a secondary. Then you’d just use the ‘nameservers’ link in the Web interface to
enter your server’s hostname and IP address as a secondary server entry. This way you could
play with the “zone transfers” that take place between authoritative servers.
