It runs as a service and send updates at a defined period.
To configure its behavior you need to set parameters in the XML file named easyDNSUpdater.exe.config

(official specs here)
The parameters are:

hostname the full hostname being updated
tld the root domain of your hostname, for example if your hostname is "" you should set "tld" to "". This field can be omitted in cases of second level domains like
myip the IP address of the client to be updated. Send "" to set record to an offline state (sets record to ""). If you are behind a firewall or NAT set this to and our system will detect your remote IP for you.
mx use this parameter as the MX handler for the domain being updated, it defaults to preference 5
backmx either "YES" or "NO", if "YES" we set to be a backup mail spool for domain being updated at preference 100
wildcard either "ON" or "OFF", if "ON" sets a wildcard host record for the domain being updated equal to the IP address specified in "myip"
time minutes between updates, >10 to avoid: "you need to wait at least 10 minutes between updates"
