www.nsupdate.info is a dynamic dns service.
You usually need it so your router (or other dyndns2-compatible client) can update a hostname, so you don't need to know or find out your current IP address.
www.nsupdate.info is simple, usable, free, friendly, secure and respects your privacy.
As far as we know, there was no service yet that is not:
You can just try it using the test account (see Register page).
Also, we have documentation — there might be some interesting stuff for you in it that is not visible or obvious on the user interface.
If you are interested in the software project, have a look at the nsupdate.info project on GitHub.
The only thing we expect from you is fair use of this service:
We reserve the right to remove any account or hostname(s) that are related to unfair use of the service - at any time and without prior notice.
This is free software and a free service, there are no warranties.
If it breaks, it breaks.
