Project Description

Check URLs and manage the respective records in DynDNS.


ddcheck accepts a list of healthckeck URLs, resolve them to IPs and makes HTTP requests directly to the IPs. When given IP is recognized as down, it will remove the record from DynDNS


  • IPv4 and IPv6 support (A and AAAA records in DNS)
  • Traversing over CNAMEs to target A/AAAA records
  • IP is marked as failed when it either timeouts (configurable in seconds) or returns defined HTTP code (for example 500, by default turned off)
  • Dry run mode: Will not change the DynDNS recods. Outputs only curl commands instead.
  • Will not delete IPs from DynDNS, when all the IPs in the dns record fail.


pip install 'git+'



DynDNS credetials can be defined either by env variables, or as parameters.
