Concept
This Free DNS hosting service is provided to help people that don't want to lose time and money with providers not always reactive to DNS changes. We can provide you primary and secondary name server for free (but if you like this service, please contribute !)
All zones hosted as primary or secondary on our main server - ns0.xname.org, are automatically replicated on our secondary server, ns1.xname.org.
Commerial Usage
A commercial usage of XName service is possible for small companies. A financial contribution is then mandatory to avoid beeing considered as abusers.
