„ Name ： It represents the host name in front of domain name. (User can define the name)
„ Reverse ： We can use the IP address to search the domain name. The DNS
included two mapped functions：Positive and reverse. For example, if we type www.test.com , the DNS will
help us to translate it to 61.218.49.29, and it is the kind of positive results, vice versa.
Example 4：
For example, we use the nslookup command in DOS, to test if the positive and reverse results are correct.
C:\>nslookup host1.test.net.tw ----------->Positive Search
Server: dns.hinet.net
Address: 168.95.1.1
Name：host1.test.net.tw
Address：61.11.11.12
C:\>nslookup 61.11.11.12 --------------->Reverse Search
Server: dns.hinet.net
Address: 168.95.1.1
Name：host1.test.net.tw
Address：61.11.11.12
The IP address of 61.11.11.12 mapped to host1.test.net.tw.
