Hi,
We encounter different result when we perform DNS nslookup with the DNS forwarding service on and off.
When the DNS Forwarding Setup turn OFF:
nslookup result as follow:
> www.yahoo.com
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
DNS request timed out.
timeout was 2 seconds.
Name: ds-any-fp3-real.wa1.b.yahoo.com
Addresses: 206.190.36.45
206.190.36.105
Aliases: www.yahoo.com
fd-fp3.wg1.b.yahoo.com
ds-fp3.wg1.b.yahoo.com
ds-any-fp3-lfb.wa1.b.yahoo.com
> www.tteest232
Server: google-public-dns-a.google.com
Address: 8.8.8.8
*** google-public-dns-a.google.com can’t find www.tteest232: Non-existent domain
=====================================
When DNS forwarding turn ON:
nslookup result as follow:
> www.yahoo.com
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
Name: www.yahoo.com.xxxxx.local
Address: 202.71.99.194
> www.tteest232
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
Name: www.tteest232.xxxxx.local
Address: 202.71.99.194
===================================
**All DNS queries will be added with the local domain (xxxxx.local) and return the same IP address 202.71.99.194, including the non-existent domain.
**This does not give us problem when browsing Internet, problem only during nslookup and rbl checking.
