NS3 and NS4 IP address change

In effort to expand our infrastructure and provide even better service to our customers there has been an ip address change to two of our nameservers: ns3.no-ip.com and ns4.no-ip.com.

The IP address change for NS3 and NS4 are:



These changes primarily effect our No-IP Squared customers, however for any Managed DNS customers who are using vanity nameserver names this may effect you as well.

The old address will continue to provide resolution while customers migrate to the new address.  We will be disabling the old address on April 8, 2008.

This is part of our planned network upgrade at our Oakland and Chicago data centers.

Have questions regarding the change? Contact our support team now.


No-IP is proud to announce our support for the new OpenDNS service known as Dnsomatic. Dnsomatic provides a free and easy way for developers and hardware vendors to integrate DDNS into their products. The services provides DNS updates to No-IP and the OpenDNS service from a scalable and standardized API. Developers will be able to write their code to work with one consistent API and be able to support several of the top service providers. As Dnsomatic gains more popularity we will be integrating it tighter into our system.

Well its been a while since our last blog entry so we wanted to update everyone.


We are proud to announce that on 11/27/2007 that we replaced both of the air filters in the heating units to our office. Yes it was a big deal and we are happy to say that no employees were injured during the upgrades. Also on a much less impressive note, we added two additional DNS servers to better serve our customers and increase reliability.

With 2008 around the corner we are hoping to update the blog more often. We have some big things on the way for 2008. Just to give you a hint, it begins with an “A” and ends with a “T”.

D-Link router woes

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.
