You can have a permanent domain name, even
if you host it on your home machine that does not have a stable IP. It is up to you to fill in a form on the Dyn.org website any time your IP (Internet Protocol)
changes. Dyn notifies the global DNS
lookup of the change and because of the short TTL (Time To Live)
in cache of the DNS name, the change effectively propagates though the
entire global DNS
lookup system in a matter of minutes. Unfortunately, some of the world’s
DNS servers run
Windows, which fails to track updates. They won’t notice changes until they
are periodically rebooted.
You can automate the process of detecting that your
IP has changed
and informing them. There is a HTTP GET protocol for
informing Dyn of IP changes and third party software. that implements
You have to update your IP
monthly, even just to keep it the same, or your account will be canceled as
To your customers, you look like a perfectly ordinary website. There is
nothing special they have to do to access you. The main catch is, you are
restricted to using one of Dyn’s free names such as mindprod.dyndns.org for you domain name.
The disadvantage of doing this is you are advertising your home
IP to hackers
which makes you more likely to be attacked.
You can have a permanent domain name of the form above, even if
you host your website at an ISP (Internet Service Provider) where it has a clumsy
name like: http://www.oberon.ark.com/~roedy
Instead, you can have a somewhat shorter name like: http://roedy.homelinux.com
is of interest to people who host their own
servers at home. It lets you manage the DNS
name services, using any domain names you want, not just their 38, with a web
based configuration. This means you don’t need to become expert in that
arcane art of MX records. You can manage subdomains of your domain. This
The Dyn people also sell traditional domain names ending in
.bz .cc .cn .com .info .name .net .org .tv .co.uk
.org.uk and .us for

Router Dynamic DNS
604 router has a small computer in it smart enough to update a
DNS server every
time it is assigned a new face IP.
The DDNS (Dynamic Domain Name Service) protocol handles updates to
the IP automatically. All
it needs in the server URL (Uniform Resource Locator), your user id, a password
and the host name (the dynamically assigned domain). No notification software or
manual updating is required, though you do need a separate DNS
server. It works with server URL domain names of the form: xxx.dlinkDdns.com or xxx.dyndns.org. You must configure the Tools ⇒ Misc ⇒ Dynamic DNS section
in the browser firmware.
