DDNS documentation

The Simply.com DDNS-service emulates the DynDNS server protocol.


The following syntax can be used to call the DDNS Service.



apikey Required The API key for the Simply.com account. Found in our controlpanel.
domain Required The name of the domain (product) you wish to update. Can be in punycode format.
hostname Required The name of the A record you wish to update. The domain should not be appended to this. Ie. use "home", not "home.example.com".
myip Optional The IP-address of the DNS record. If this field is not the provided, the IP of the client (REMOTE_ADDR) is automatically used instead.


dnserr Something went wrong
nochg The record is already set to the IP given.
badauth Invalid login
abuse The record has been updated/changed too many times in a given period.
good The record has been updated

Curl example Recommended

Use the following curl command to set home.example.com to the external IP of the requesting client:

# curl -s -L "https://api.simply.com/ddns.php?apikey=APIKEY&domain=example.com&hostname=home"

You can set this command to run in a crontab, on a local machine, every 15 minutes or so.
