$ host -t NS mydomain.org. ns0.xname.org Using domain server: Name: ns0.xname.org Address: 195.234.42.1#53 Aliases: mydomain.org has no NS record
Maybe they stopped accepting new customers, I don't know.
So I looked around and found a few alternatives:
mybind.com
CloudFlare
FreeDNS
EntryDNS
PointDNS
Update: I tried mybind.com and CloudFlare and both worked like a charm for what I needed to do (define a few A-name, CNAME and MX records).
