如何检查名称服务器的反向 DNS

我用来whois example.com检查哪些是该域的权威名称服务器。现在我想知道哪些是 IP 地址块的权威名称服务器，用于它们的 PTR 记录，我该如何检查？谢谢。

答案1

将信息放入 whois 取决于区块地址的所有者 - 这不是强制性的。如果所有者放入，您可以询问例如

whois 1.254.150.in-addr.arpa

如果您想要请求权威名称服务器，最好按每个八位字节降序排列 ns-es，例如：

undefine@undefine-ThinkPad-T430s:~$ host -t NS 150.in-addr.arpa
150.in-addr.arpa name server apnic.authdns.ripe.net.
150.in-addr.arpa name server ns1.apnic.net.
150.in-addr.arpa name server tinnie.arin.net.
150.in-addr.arpa name server ns3.apnic.net.
150.in-addr.arpa name server ns4.apnic.net.
150.in-addr.arpa name server ns2.lacnic.net.
150.in-addr.arpa name server apnic1.dnsnode.net.
undefine@undefine-ThinkPad-T430s:~$ host -t NS 254.150.in-addr.arpa
254.150.in-addr.arpa name server ns.ripe.net.
254.150.in-addr.arpa name server rose.man.poznan.pl.
254.150.in-addr.arpa name server sunflower.man.poznan.pl.
undefine@undefine-ThinkPad-T430s:~$ host -t NS 1.254.150.in-addr.arpa
1.254.150.in-addr.arpa name server orion.put.poznan.pl.
1.254.150.in-addr.arpa name server sol.put.poznan.pl.
1.254.150.in-addr.arpa name server sunflower.man.poznan.pl.

另一个选择是使用 dnstracetool。例如：

undefine@undefine-ThinkPad-T430s:~$ dnstracer -4 -s A.ROOT-SERVERS.NET 140.141.180.213.in-addr.arpa
Tracing to 140.141.180.213.in-addr.arpa[a] via A.ROOT-SERVERS.NET, maximum of 3 retries

 |\___ a.in-addr-servers.arpa [in-addr.arpa] (199.212.0.73) 
 |     |\___ tinnie.arin.net [213.in-addr.arpa] (199.212.0.53) 
 |     |     |\___ dns3.onet.pl [141.180.213.in-addr.arpa] (213.180.147.200) 
 |     |     |\___ dns1.onet.pl [141.180.213.in-addr.arpa] (213.180.128.242) 
 |     |      \___ dns2.onet.pl [141.180.213.in-addr.arpa] (213.180.137.160) 
 |     |\___ tinnie.arin.net [213.in-addr.arpa] (2001:0500:0013:0000:0000:0000:c7d4:0035) Not queried
 |     |\___ pri.authdns.ripe.net [213.in-addr.arpa] (193.0.9.5)

您还可以使用 dig 来跟踪 dns 服务器，例如：

undefine@undefine-ThinkPad-T430s:~$ dig +trace 141.180.213.in-addr.arpa
