DuckDNS still points to the old home IP after a power outage
A setup without a can get a new internet address after a router restart. In this case, a NAS was already updating DuckDNS automatically when the home IP changed. After a power outage, the system rebooted and the ISP router received a new .
DuckDNS showed the new address correctly. Even the next day, devices and still received the old IP when they looked up the DuckDNS domain. That can stop to a NAS or home VPN even when the server itself is working.
One possible fix being considered is using the router’s built-in DDNS update feature and pointing device DNS settings toward the router, but it is not clear whether that would be faster or still depend on propagation time.
Key points
- A home internet connection without a can change address after a router restart.
- The NAS updated DuckDNS with the new , but some devices still resolved the old IP.
- access can fail if the still points to the old home address.
- Using the router’s own DDNS feature might help, but it may not remove propagation delays.
- owners should test actual DNS lookup results after outages or router reboots.
