chang ip
 

i'm using cable provider to connect on Internet :)
i trud to change mu ip with dhcpcd and it worked...
my question is...what happens if i change ip to already asigned ip?

If you use an IP that is assigned to another active machine on a network, all sorts of strange things can happen (not being able to connect at all, randomly getting dropped offline, etc.)

If you just mean that you obtained a new IP from your ISP, don't worry- they take care of making sure you get a unique IP.

i mean change ip to whatever i want (on my network) not obtained ip from isp....but ok thanks :)

If you are using DHCP, why are you changing/setting the IP manually? That pretty much defeats the purpose of DHCP, no?

well yes...but i'm just looking around :)
