And for extra credit - Is it possible to find the origins of conflicting DNS records?

推荐答案

你会想要给定域名的SOA（开始授权）记录，这是您使用普遍可用的 nslookup 命令行工具来完成的：

You'll want the SOA (Start of Authority) record for a given domain name, and this is how you accomplish it using the universally available nslookup command line tool:

command line> nslookup
> set querytype=soa
> stackoverflow.com
Server:         217.30.180.230
Address:        217.30.180.230#53

Non-authoritative answer:
stackoverflow.com
        origin = ns51.domaincontrol.com # ("primary name server" on Windows)
        mail addr = dns.jomax.net       # ("responsible mail addr" on Windows)
        serial = 2008041300
        refresh = 28800
        retry = 7200
        expire = 604800
        minimum = 86400
Authoritative answers can be found from:
stackoverflow.com       nameserver = ns52.domaincontrol.com.
stackoverflow.com       nameserver = ns51.domaincontrol.com.

原始（或主名称服务器在Windows上）行告诉您， ns51.domaincontrol 是 stackoverflow.com 的主名称服务器。

The origin (or primary name server on Windows) line tells you that ns51.domaincontrol is the main name server for stackoverflow.com.

输出所有权威服务器的结束，包括给定域的备份服务器。

At the end of output all authoritative servers, including backup servers for the given domain, are listed.
