why can't find server name for address?

server 10.0.0.1 works fine, but why I have to set 10.0.0.1 manually?
cmd nslookup
*** Can't find server name for address 10.0.0.1: Non-existent domain
Default Server: ns.sdjnptt.net.cn
Address: 202.102.128.68

> server 10.0.0.1
Default Server: [10.0.0.1]
Address: 10.0.0.1

> www.3721.com
Server: [10.0.0.1]
Address: 10.0.0.1

Name: www.3721.com
Address: 1.11.1.111

Because you should not have 202.102.128.68 listed in TCP/IP properties in
the first place.
Then it appears the server at 10.0.0.1 does not hanve a reverse lookup zone
for the 10.x.x.x subnet, or the PTR for 1.0.0.10.in-addr.arpa. is missing
from the zone.
