Tunnel-DomainName?

[Claudia Cordova Yamauchi]

Dear all,

I'm trying to register my tunnel, without any success... I have INICTEL-PE 
and we are connecting NITCOM and have some trouble with that DomainName 
thing. 

Syntaxis:
IPv6 in IPv4 <Src DomainName> -> <Dst DomainName> <IPv6-Site> <Protocol>
Src DomainName: INICTEL-PE or 6BONE COMPENDIUM-AR  INICTEL-PE (Bad)
Dst DomainName:NITCOM (Bad)
IPv6-Site: NITCOM (good. I guess :-) )
Protocol: BGP4+ (good. I guess :-) )

How can I get a domain name? 

Thank you in advance
Claudia
