Dynamic DNS Services - 100% FREE for all Top Level Domains


Note: We don't provide static IPs but associate your dynamic IP with a static host/subdomain name.

DNS stands for Domain Name Systems that will make your computer accessible any time, anywhere by associating a domain name of your choice to dynamically changed IP address. Dynamic DNS allows you accessing to your home computer with remote desktop, or running web site, email server, FTP service at home.

Dynamic IP Updates Made Easy

Simply run curl or wget command to update your dynamic IP for any hosts or domains under your account.
 >> curl https://api.dnsexit.com/dns/ud?apikey=API-KEY -d host=host1.yourdomain.com,host2.yourdomain2.com
On any machine behind the router, just schedule a job to run the above command every few minutes. Our system will automatically detect your public IP address and update your hosts to the new IP. Alternatively, you may add parameter -d ip=xx.xx.xx.xx to overwrite the IP. For multiple hosts, just seperate them by , (comma). The API Key can be generated at your DNS Exit account settings.
The return is JSON file with a successfull update like:
 {"code" : 0, "message" : "Success - some details about the update"}
code:0 indicates successfull updates while code:1 indicates IP address not changed. Other returning codes indicates errors.

Besides the easy-to-use web interface to manage your DNS, We also provide DNS API to update your DNS records remotely.
