Recently, I am taking tutorial of network class and there are a lot of network concept
i am getting confused, so I try to start to understand my home PC and network to solve my network concept problem.
At home, I get two PC with one at window 7 and the other at Window XP which is connected to one device we call ADSL something like the photo I include at web link
When I go to broadband internet, I log into window 7 or PPPoE connection utility or
software with my login and password that is provided by my ISP company
After connection, I try ipconfig on cmd.exe,and I got the following message
Ipv4 IP 219.77.x.x
subnet mask: 255.255.2555.2555
I am using auto configuration mode for the connection setup for external IP and internet .
1- the device of ADSL means that is router plus modem, Right ?
2- router means network switches like the 4 ports in the photo attached, Right ?
3- DefaultGateway or Gateway for my case that is refered to the my ADSL router, RIght
4- Why the default gateway is 0.0.0.0 ?
5- I google default gateway 0.0.0.0, and found one article how to delete 0.0.0.0 default gateway (http://www.shayanderson.com/microsoft-windows/windows-7-fix-0-0-0-0-default-gateway-issue.htm
) but it doesn't work, but 0.0.0.0 is still there,why?
6- I also tried to use the command
netsp int ip reset c:\resetlog.txt & netsp winsock reset c:\winsock.log and reset the computer and logging again, but 0.0.0.0 is still there and not deleted, why ?
Hope you write more like for teaching student in a class for those questions
