More results from the IPCONFIG command

First you have to determine how your computer is connected to the internet. To do so, open a Command window (instructions here).

Please refer to "Interpreting the IPConfig command" for a basic description. This screen adds the complexity of multiple networks.


Shown is a Windows 7 networks available screenshot showing 2 connected networks (one wireless and one wired) and 3 more available networks, including a guest offering.

Explanation:

LAN adapter Wireless Network Connection:
Details of this one of multiple network connections follow.

IPv4 Address. . . . . . . . . . . : 192.168.15.102
The address of this computer

Default Gateway . . . . . . . . . : 192.168.15.1
The location of the closest router protecting this computer.
If there are multiple routers in line you could also configure those routers, if you knew how to log into them.
This might be the situation if you installed your own router and the ISP's modem also included a router.

Test this out by connecting a computer directly to the modem and comparing the computer's IP with the result by entering "ip" into a Google search. If the computer IP matches your public IP, you are connected directly to the naked internet.

DHCP Server . . . . . . . . . . . : 192.168.15.1
The location of the device that assigns your IP address. With a simple network, this is usually your closest router.

DNS Servers . . . . . . . . . . . : 8.8.8.8
The servers that look up the address of sites on the internet. Usually your router just asks the network above it; which for a home setup is your ISP. You can enter any valid DNS server and may find other DNS servers that are faster or provide features such as child-safe filtering. Just enter their address in the appropriate field on your router or your computer's network configuration.
