dns

Hi folks,
I've created CNAME record in DNS and now I can resolve alias name as expected:

Code:

C:\Users\liandy>nslookup
Default Server:  utilcn3.cn.example.com
Address:  10.182.96.20

> alias.example.com
Server:  utilcn3.cn.example.com
Address:  10.182.96.20

Non-authoritative answer:
Name:    cname.example.com
Address:  10.242.6.20
Aliases:  alias.example.com

But I have a question that, can I get alias name from ip address? I mean is there a way that I know what alias names bound for a cname(cname.example.com, 10.242.6.20)? As currently, nslookup for a ip only returns the cname but no alias name:

Code:

C:\Users\liandy>nslookup 10.242.6.20
Server:  utilcn3.cn.example.com
Address:  10.182.96.20

Name:    cname.example.com
Address:  10.242.6.20

Thanks!

Hi,

try host. Eg

Code:

host 10.242.6.20

EDIT: Sorry, that is completely the wrong answer. Now I've destroyed the threads zero reply status. If it is any consolation I'm trying to find the correct answer...
