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


Note: We don't provide static IPs. Our DynDNS simply link your dynamic IP to a static domain name. Thus, you can access the network with the domain name no matter how the IP changes.

Dynamic IP Updates Made Easy with curl

At your Windows/Mac/Linux, simply schedule a job to run the following curl command once every few minutes. Most OS should has curl built in. Windows got curl built in since Windows 10 build 1803, released early May 2018.
>> curl https://api.dnsexit.com/dns/ud/?apikey=API-Key -d host=host1.domain.com,host2.domain2.com
Witch the command, 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 created at your account Dashboard -> 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.



To test how it works on browsers, you can simply paste the following URL adress to a web browser:
https://api.dnsexit.com/dns/ud/?apikey=API-Key&host=host.domain.com
Note: You need to replace the API-KEY and hostname with your own api key and hostname

curl (short for "Client URL") is a command line tool that can communicates with a web server with a relevant URL. Or in other words, it is just like a text based web browser. The curl command is built in most Operating Systems including Linux, Unix, MacOS, and Windows (sinc Windows 10 ). If your windows does not have curl command, you can refer to install curl on windows to learn how to install it.



What is Dynamic DNS?




Dynamic DNS makes a dynamic IP address act like it is a static IP address, meaning it does not change. It does this by utilizing a hostname and our Dynamic Update Client to keep your hostname updated with the correct IP address.


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

ns1.dnsExit.com ns2.dnsExit.com ns3.dnsExit.com ns4.dnsExit.com

Next, you need to Setup DNS for the domain. The DNS (Domain Name Systems) is the internet service that translates your domain names into IP addresses.


4.    Automatic Dynamic IP Updates

If you are running Window NT or Linux/Unix, you can use command nslookup to check your IP settings of your hosts at dnsExit.com name servers. Under DOS prompt(Windows) or shell prompt(Linux/Unix), type command nslookup; then specify the name server as ns1.dnsExit.com; finally type one of the host names in your DNS records. You should see the IP of the host displayed on the screen.
