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.
Primary and secondary name server for free. All zones hosted as primary or secondary on the main server ns0.xname.org are automatically replicated on the secondary servers ns1.xname.org and ns2.xname.org.
The DNS service at XName itself works badly (e.g., the security certificate is expired in 2012). But other working DNS services are based on the source code of XName (e.g. FreeDNS::42).
