Dynamic DNS Clients - Software, Specifications and Guidelines

To update your DNS, you can always login to your account and click on Edit DNS link next to the domain name to bring up the domain DNS page. To update the changed IP automatically, you should download one of the following dynamic DNS clients and install it on your PC. If you have a router, the IP Client will automatically pick up the router's IP address and update it to our system.


  To make the remote update more secure, you should login to your web account, then go to "Account Profile" -> "IP Update Password" to setup a password for IP remote updates. You then use your web login username and the choosen password for your IP Update clients.

Windows All Platforms:

IP Updater Windows (Version 2.0): It runs as Windows service and will start automatically under Services with name DNSExitService (Right click Start -> Run -> Open: services.misc).

Download Windows IP Updater 2.0 (Run as Windows services)

Note: Windows 10 defender may block the download and install of the software, you should ignore that and turn off the defender before downloading. Certain anti virus may falsely list the software as malware too and you should just ignore that.


IP Update (Version 1.70)(Free) is dnsexit.com's own dynamic DNS update utility for Linux/Unix. ipUpdate-1.70.tar.gz file should be for all Unlix/Linux platforms. The RPM version can work on most Linux platforms. The Debian package is for Debian Linux distribution only.

ipUpdate-1.6-2.noarch.rpm The RPM package that works on most Linux platforms. To install:
>> rpm -i ipUpdate-1.6-2.noarch.rpm
>> /usr/sbin/dnsexit-setup.pl      # to setup (please choose daemon mode)
>> /etc/init.d/ipUpdate start      # to start the program
Refer to "file /usr/share/ipUpdate-1.6/doc/README.txt" for instructions.
ipUpdate-1.6-3.deb The Debian package that works on Debian Linux distribution. To install:
>> dpkg -i ipUpdate-1.6-2.deb
>> /usr/sbin/dnsexit-setup.pl      # to setup (please choose daemon mode)
>> /etc/init.d/ipUpdate start      # to start the program

Tips for the Linux script:
  • Version 1.71 has the option to run as daemon and autostart after reboot. It will automatically insert crontab to start the script at system startup.
  • File "/tmp/dnsexit-ip.txt" will cache the ip address of the last successful IP update to our system. For next update, if the IP stays the same, the update request won't be sent to our server. You can simply change the IP at dnsexit-ip.txt file to force the update to DNSEXIT.
  • File "/var/log/dnsexit.log" contains the update history for your IP.

If you want to write you own dynamic IP update clients, please download the document here. If you would like to share your program with other users, please contact us at supportdnsExit.com. We will post your program on this page.

We also provide you a URL that you can use to update your domain/subdomain IP from any internet connection, anywhere. This means that if you do not have one of the automatic update clients you can still perform painless updates to your subdomain IP by posting the following URL on a browser:
replacing the form values with your own account and domain data.
myip is optional. If not set, the IP address of your network will be detected and used as the IP for the host(subdomain).
host can have multiple hosts(subdomains) updated at the same time by seperating each host by ;. ie. host=host1.mydomain.com;host2.otherdomain.com.
password is the password for your web login. However, it is recommended that you setup a dynamic IP update password that is different from your web login password. You can login to your account, then go to "Account Profile" -> "IP Update Password" to setup dynamic IP update password.
