DNS(DOMAIN NAME SYSTEM) AND WEB SERVER CONFIGURATION
STEP 1:
DNS SERVER
- GOTO DNS SERVER , CLICK ON DESKTOP, SET IP ADDRESS AS 192.168.1.2, AND SUBNET MASK AS 255.255.255.0
- CLICK ON DNS SERVER , GOTO SERVICES, CLICK ON HTTP, CHOOSE ON, GOTO index.html and click edit and set as per your wish and click save.
WEB SERVER
- CLICK ON CONFIG, SET DNS SERVER AS 192.168.1.2
- GOTO DESKTOP AND SET IP ADDRESS=192.168.1.1, SUBNET MASK AS 255.255.255.0, DNS SERVER =192.168.1.2
PC
- GOTO DESKTOP, SET IP ADDRESS=192.168.1.3, SUBNET MASK=255.255.255.0, DNS SERVER =192.168.1.2
STEP 2:
GOTO DESKTOP , CLICK ON WEB BROWSER, IN URL TAB GIVE IP ADDRESS OF WEB SERVER I.E. 192.168.1.1
STEP 3:
LETS ADD WEBSERVER IN DNS SERVER, GO TO DNS SERVER
, CLICK ON SERVICE, GO TO DNS, IN NAME TYPE:FACEBOOK.COM AND IN ADDRESS TYPE:192.168.1.1 AND CLICK ADD AND SAVE.
go to pc
STEP 4: GOTO DESKTOP , CLICK ON WEB BROWSER, IN URL TAB GIVE INAME= FACEBOOK.COM , WE WILL GET
SO WHETHER WE TYPE NAME OR IP ADDRESS WE WILL GET SAME .
