Is that complicated to fix the DDNS excessive and constant updating on the D-Link DGL-4300 router or D-Link DNS-323.

These devices have been around for a while and still the bug that plague the DDNS has not been fixed.
It doesn't matter the settings, when the DDNS is setup on D-Link devices it will constantly request updating of the IP address to a DDNS service, even thought the IP has not change.
What's the point to include the DDNS functionality, a feature that does not work and no one can use?

It should not be that difficult since other manufacturers with less expesive devices have that feature working.
