问题描述

如何找到冲突 DNS 记录的来源?

How can I find the origins of conflicting DNS records?

推荐答案

您需要给定域名的 SOA(授权开始)记录，这就是您使用普遍可用的 nslookup 完成它的方式 命令行工具:

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.

origin(或 Windows 上的主要名称服务器)行告诉您 ns51.domaincontrol 是 的主要名称服务器stackoverflow.com.

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

在输出的末尾列出了所有权威服务器，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.
