Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 218.71.169.205 is found by looking up the PTR record for
205.169.71.218.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.
See How Reverse DNS Lookups Work for more information.
How I am searching:
Asking g.root-servers.net for 205.169.71.218.in-addr.arpa PTR record:
g.root-servers.net says to go to tinnie.arin.net. (zone: 218.in-addr.arpa.)
Asking tinnie.arin.net. for 205.169.71.218.in-addr.arpa PTR record:
tinnie.arin.net [199.43.0.195] says to go to ns.zjnbptt.net.cn. (zone: 71.218.in-addr.arpa.)
Asking ns.zjnbptt.net.cn. for 205.169.71.218.in-addr.arpa PTR record: Reports 205.169.71.218.broad.nb.zj.dynamic.163data.com.cn. [from 202.96.104.18]
Answer:
218.71.169.205 PTR record: 205.169.71.218.broad.nb.zj.dynamic.163data.com.cn. [TTL 78000s] [A=218.71.169.205]
218.71.169.205 PTR record: mail.nst.com.cn. [TTL 78000s] [A=218.71.169.205]
Details:
You have more than one PTR record for 218.71.169.205. This is legal, but most programs will only use
the first PTR record listed (which may vary). Best practice is to have just one PTR record.

这个上面的意思 应该是说 我的IP已经做了反解吧!
请帮我看下
