DNS. Non-authoritative answer. canonical name

domain-name-system

I have a DNS understanding problem. (Using Windows AD integrated DNS, Windows 2012)

I'm trying to find out why I get the reply I get.

When going to "www.company.cn" I get an internal IP. But I do not have any records in my DNS with "www.company.cn"

A few NSLOOKUP results:

The simple one:

C:\WINDOWS\system32>nslookup
Default Server:  DC.company.net
Address:  192.168.0.5

> www.company.cn
Server:  DC.company.net
Address:  192.168.0.5

Non-authoritative answer:
Name:    www.company.dk
Address:  192.168.0.15
Aliases:  www.company.cn
> exit

As I understand, the "Non-authoritative answer" tells me its not from my local DNS I get the data (Also I do not have a company.cn zone in my DNS)

More NSLOOKUP:

C:\WINDOWS\system32>nslookup -type=soa www.company.cn
Server:  DC.company.net
Address:  192.168.0.5

Non-authoritative answer:
www.company.cn     canonical name = www.company.dk

So it tells me it's from a CNAME record? (And somehow related to "www.company.dk")

I do have a "www.company.dk" DNS entry in my DNS:

C:\WINDOWS\system32>nslookup
Default Server:  DC.company.net
Address:  192.168.0.5

> www.company.dk
Server:  DC.company.net
Address:  192.168.0.5

Name:    www.company.dk
Address:  192.168.0.15

If I try the nslookup SOA command on www.google.com, I get another, more usefull answer:

C:\WINDOWS\system32>nslookup -type=soa www.google.com
Server:  DC.company.net
Address:  192.168.0.5

google.com
    primary name server = ns1.google.com
    responsible mail addr = dns-admin.google.com
    serial  = 180758758
    refresh = 900 (15 mins)
    retry   = 900 (15 mins)
    expire  = 1800 (30 mins)
    default TTL = 60 (1 min)
ns1.google.com  internet address = 216.239.32.10

So here it tells me the name server where it got the reply from. (which understandably is not a local server, and not within my control)

In general I just want to know where I can control the DNS record of "www.company.cn"

How can I get more useful information as to where to control www.company.cn?

Best Answer

In the last query you asked your local DNS server about google,unless your company is google.com the SOA lookup for google tells you nothing about your local DNS zones, only that you can resolve public/internet zones.
Did you mean to ask googleDNS about your domain, to see your records are in public DNS; if so you wanted

nslookup -type=soa company.cn. 8.8.8.8
