Posted by In a dynamic environment it’s hard to keep your DNS up-to-date. Updating the DNS server is a task which is mostly forgotten during server maintenance.
Created just a simple one-liner for checking the registered suffix and do a ping test.
Yeah I know this one is not dummy proof, but hey! t helped me checking 10.000 records in 2 minutes, so maybe i can help someone with sharing this. 🙂
