j.gtld-servers.net gives the reference info about the domain mydots.net.
It says the dns servers for mydots.net is ns[1-2].dnsbed.com, following with two NS's IP addresses.


My question is, when other BIND Cache get this reference, will it use the IP addresses directly?
Or will it use the IP addresses get from the authoritative server?

I ask this because, when the IP addresses get from reference, are different from the ones get from the authoritative server, what will be happened?

Thanks for your kind helps.
