You need DHCP (or maybe BOOTP) to get an IP address in the first
place. You can boot Windows, use its DHCP to get an address,
reboot into Linux, and enter that address statically. However, I
recommend that you go to www.isc.org and get the official package.
If you use IP addresses that don't belong to you, you'll probably
end up causing denial-of-service attacks for other ADSL users. A
few months ago I was unable to connect to my home server (properly
logged-in, with dhclient renewing the lease daily) and instead got
somebody's FreeBSD box using "my" IP address. This happened twice,
and I had to force a new address for myself by rejecting the DHCP renewal
offer.
If you leave your computer connected all the time running dhclient,
your IP address will probably stay the same for long periods of
time. However, last weekend I was doing a bunch of system
re-configuration and upgrading, and I went through several IP
addresses. My advice (others will disagree) is to play by their
rules, use DHCP and 'log in' to their secure web page, and only
use your static host name (e.g. "a0a00123.sympatico.bconnected.net")
to point to your machine. Registering your ADSL IP address as an
Internic DNS server would be a Bad Thing...

p.s. I had problems with RedHat's "dhcpcd", though maybe this is
fixed in the current release. I forget what the issues were
exactly, but I had better luck with the ISC 'dhclient'.
