I'd like to query the DNS records until get the right domain name.
我想查询DNS记录,直到获得正确的域名。
For instance, given www.subdomain.site.com.br, be able to dig from .br until site.com.br.
例如,给定www.subdomain.site.com.br,能够从.br挖掘到site.com.br.
Which is the most (protocol-speaking) way to achieve that? An recipe using dig/nslookup would be best.
实现这一目标的最多(以协议为导向)方式是什么?使用dig / nslookup的配方最好。
Thanks.

#1
dig www.mysite.domain.com @a.root-servers.net
you'll get the next level from there. Just replace the portion after the '@' and keep recursing until you query a server that gives an answer rather than additional information
你会从那里获得下一个级别。只需替换'@'后面的部分并继续递归,直到您查询提供答案的服务器而不是其他信息
#2
dig +trace www.subdomain.site.com.br
will show you exactly what happens.
会告诉你到底发生了什么。
