The most important function of DNS servers is
the translation (resolution) of human-memorable domain names and
hostnames into the corresponding numeric Internet Protocol (IP)
addresses.
It is used bunch of records to do these things such as NS records,CNAME, TXT ,A records etc. these bunch of records details are stored in db file according to the domain.
In this exercise we can get brief idea of these records but it is not actual one in the DNS server.
1st set the IP address to the DNS server
double click server -> config -> fastethernet0 -> set static IP address 192.168.1.3 and subnet mask 255.255.255.0
double click server -> config -> fastethernet0 -> set static IP address 192.168.1.3 and subnet mask 255.255.255.0
Add a records to the DNS server
In this example the host 192.168.1.50 www.testingpage.com use aliasing name such as mytesting and testing.com. These alias name enter as CNAME records in to the DNS server in the db file. Then enter the A record for the www.testingpage.com.
mytesting CNAME www.testingpage.com
testing.com CNAME www.testingpage.com
www.testingpage.com A record 192.168.1.50
Then we can use host name www.testing.com to mytesting,and testing.com in the browser
