pfSense Dynamic DNS
I believed the dynamic DNS service would refresh your DNS entries upon detecting changes. However, it appears to be executing a scheduled task at 1:01 PM daily. Over the past couple of days, my ISP has altered my IP address three or more times each day, which is quite bothersome. A quick fix involved adjusting the cron job, but I found it odd since the daemon seems to handle it automatically.
The links use PPPoE, and your PPPoE setup stays unchanged while the Ethernet link adjusts within roughly fifteen minutes.
It seems you're asking about how DNS agents or clients operate within certain time frames. They likely rely on scheduled polling rather than real-time updates, which could explain the timing issues you're noticing. Without deeper system details, it's hard to pinpoint the exact cause. Could you clarify if you're referring to lease durations or network configuration?
I’ve maintained my IP for several months, so even after expiration it was reinstated. The lease duration isn’t clear, but I’ll check again when I’m back home. It’s possible they’re performing maintenance at the ISP—hard to say without more info. Right now, I just adjusted the cron job, which works fine. I’m surprised since the manual mentions updates versus daily changes.
