DOS command to add (assign) an IP address to machine

hello,
I want to know is that true that there is a DOS command that allows you to add (assign) an IP address to the machine !!!!!!!
in fact I want to know that for ethernet router, So what if the network card with a single PC on the command line backs up!
thank you in advance :)

In the days of DOS, the IP was not used at all in micro-informatics.
What version of DOS do you use? You use drivers NDIS2 or "Packet"?
Normally, the settings of the IP address are in the CONFIG.SYS file or Protocol.ini (often in the NET).

I'm on Win XP but just curious I ask if there is a command to assign an IP address to an interface of a computer through DOS (Start - Run - cmd).

netsh /?
netsh interface /?
netsh interface ipv4 /?
netsh interface ipv4 set /?
netsh interface ipv4 set address /?

You can change the IP from the command prompt.

The command is:
to change IP and default gateway:
netsh int ip set address "local area connection" static 192.168.0.101 255.255.255.0 192.168.0.254 1

to change DNS:
netsh int ip set dns "local area connection" static 192.168.0.254 primary

This is assuming 3 things.
1) The network adapter you're trying to change the IP for is "local area connection". It could also be "local area connection 2" or "wireless network connection". Look in your control panel for the correct name
2) The IP you want to set is 192.168.0.101, change this to whatever IP to want to use.
3) The default gateway and dns are the same IP. If you are using some kind of router they usually are. Change this to match your network config found with the command ipconfig /all

You will need to run both commands to change the IP.
