Recently No-IP has disabled all dns updates from D-Link routers to our main website www.no-ip.com. Over the past 3 years No-IP has supported the ability of these routers to perform updates to our dynupdate.no-ip.com host. We also allowed updates for people that incorrectly configured their router to point at www.no-ip.com. Unfortunately, traffic from these routers constitutes 50% of the requests our website receives and actions must be taken to reduce the impact from these misconfigured routers.
If you are using a D-Link router as your update client, please verify that your “Server Address” is dynupdate.no-ip.com and NOT www.no-ip.com. Also take the time to verify you still have the correct email address for the username and correct password and are running the most recent version of firmware for your router.
Users currently performing updates through www.no-ip.com will receive a “too many updates” error response. Adding salt to the wound, older D-Link routers do not listen to response codes (hence the insane amount of traffic) so at some point in the future we may begin blocking these at the connection level.
More information on configuring your D-Link router can be found over here.
