How to reset TCP / IP

Recently I tried to change ip with IPSwitcher_v1.0.0.7 which I downloaded, somehow after changing ip internet connection wasn't connect. This seems to be ignorance that I choose to change the IP. After the trace was found in IPv4 there are two IP addresses like in the picture below. I asked each person, the answer was zero.

Finally I found the answer to the problem, namely to reset the TCP / IP. At first I run without a modem connection results are not satisfactory, the second step by installing / modem connection and the results are OK.
Here are the steps to reset TCP / IP:

a. Click Start, type "cmd" (without the quotes) in search area
b. Right Click "cmd" in the Start Menu, choose "Run as administrator".

c. Type netsh int ip reset command

d. After that restart the computer for no effect of any change.
The result is internet connection runs normally,
I also check the IP again and the results are normal again where IPv4 addresses only one row.

So, hopefully a little knowledge can be useful for you.
