 Newbie - DHCP question
Is there a way to force my IP address to change if I have DHCP for my
cable internet connection?

I tried "dhcpcd -k" to clear the cache and restarted the DHCP client
daemon but it still kept the old address.

I'm using Linux Mandrake 7.2.

Most DHCP server keep track of the hardware MAC address when they dole
out IP addresses and try to assign the same address when a client
reconnects. When you request a new address, the server still
knows your MAC address and tries to give you the same IP address if it is
still available. Clearing the cache on the server, NOT the client (dhcpcd
is the client) might do the trick, but chances are the dhcp server will give
you the first available IP address which may very well be what you got

The easiest way to change your IP address is to override it with
ipconfig. See the man or info pages on how to use it.

(yes I saw your posting that you meant ifconfig).

Depending on how your ISP assigns you IP-numbers, I wouldn't do that - or you
wouldn't be able to. If it is a cable-provider, the provider gives you the IP
based on the MAC-adress of the cable-modem, which you can't change using

Other providers base their entire system on the MAC-adress of your card.
Changing it could result in not being able to go onto the internet anymore.

But most providers probably don't...
