Dynamic DNS

From XpertDNS

Use our Dynamic DNS service if you would like to host your own web server, mail server, ftp server, etc. but you do not have a static ip. Combine the power of dynamic DNS with a site monitor for a free failover solution.

Please watch our flash tutorial if you need assistance configuring the DNS control panel.

Here is an example dynamic zone configuration.

Set the TTL's of your zone's A records low, like 180 seconds. We will allow settings as low as 5 seconds but anything lower than 180 seconds and caching name servers may ignore this time and just slow things down.

Dynamic DNS Update API

You can use our API to make dynamic update to your DNS A records. We have improved our API; the old API will still work and details are available here.

URL:


Supported request types

  • GET or POST

While our API supports both GET and POST, we recommend POST for better security.

API Variables 

uname		username as registered with our system   64 character length limit
password	encrypted MD5 password hash. 64 character length limit
dynid 		record ID for the A or PTR records you'd like to update. Multiple IDs can be updated in a comma delimited list. 255 character length limit
ip 		IP address for this record. If "remote" is submitted as the value, we will use the client ip.


GET Update String:

  • https://www.xpertdns.com/dyndns.php?dynid=DynID&ip=ipaddress&uname=username&password=password


Our new API requires that your password is encrypted. You can use this form to encrypt your password.
