[dns-operations] register nameservers in different TLD's NS

[风河]

 Hello,

 My domain name, say nsbeta.info, has registered the nameservers in 
 info's servers.
 So, the domain nsbeta.info can use the nameservers of itself as its 
 auth servers.
 But, a domain in other TLD, say example.com, can't use the nameservers 
 of nsbeta.info as its auth servers.
 How can I register a info nameserver in a com's NS?

 Thank you.
