Simple Dynamic DNS Server

Converting words into numbers since 1987™.

Create a new DNS record or update an existing DNS record

.example.com

• .example.com
• .specificgeneralisations.com
• .generalspecifics.com
• .mycompanyname.com

OK

Your current IP address is 192.168.0.88.

What is Dynamic DNS?

It's a way of referring to your machine by an internet domain name (e.g. mycomputer.example.com) rather than a dotted IP address (e.g. 198.51.100.113).

You must already own the internet zone that contains the desired subdomain (e.g. example.com in this example).

How does it work?

By updating the DNS (Domain Name System) to return your computer's current IP address when your computer name is queried.

The DNS system needs to be updated every time your public IP address changes, using any of the clients or interfaces listed below.

If you have a static IP address then your IP address doesn't change, and you don't need to use Dynamic DNS.

Clients

You can use the ddclient client to update your IP automatically, using a configuration similar to the following:

# /etc/ddclient/ddclient.conf
#
daemon=5m                   
use=web
web=http://dyndns.example.com/nic/checkip.html  
server=http://dyndns.example.com/nic
protocol=dyndns2 login=secretlogin, password=secretpassword host.example.com

Interfaces

This service provides a number of interfaces:

HTML

You are currently viewing the HTML interface for this service.

Host names and IP addresses can be entered using the two input fields and the green button at the top of this page.

DynDNS

Alternately, you may wish to use the dyndns-compatible interface:
http://dyndns.example.com/nic/checkip.html
http://dyndns.example.com/nic/update?system=dyndns&hostname=host.example.com (HTTP Basic authentication)
http://dyndns.example.com/nic/update?system=dyndns&hostname=host.example.com&myip=x.x.x.x (HTTP Basic authentication)

ZoneEdit

Or even the zoneedit-compatible interface:
http://zoneedit.example.com/checkip.html
http://zoneedit.example.com/auth/dynamic.html?dnsto=x.x.x.x&host=host.example.com (HTTP Basic authentication)

*cough* route53 *cough*

Or some new exciting thing I've just thought of that uses XML or JSON, and uses the word 'cloud' repeatedly in the description.
