Subject:   CVSup with a dynamic IP

I am connected to the internet with ISDN, and use sppp to connect. I
get assigned a dynamic IP every time I connect, so I don't have a
static IP I can point to, neither a static host name.

Now, I'd like to use CVSup to upgrade my system to -STABLE, and update
my ports tree. I got the stable-supfile from the website and added the
ports tag, and tried using `cvsup stable-supfile` (I am using X).
CVSup complained it can't locate an IP for my hostname. My hostname
was set to `asmodean', which is a made up name, because I wan't sure
this had any real use for me, since I'm not a server. Anyways, after
this complaint I changes my hostname to plain old `localhost'. Tried
the command again, and CVSup came up. I tried clicking that play
button to begin downloading, and walla, I get a message that I was
denied a connection (I tried connection to cvsup3.freebsd.org).

Logic tells me this: the CVSup server needs my IP for some reason,
since it decides to be real smart and contat my IP instead of using
the TCP/IP session already open, so it needs to get my IP, which the
CVSup client provides. The CVSup client provides the IP it gets from a
reverse domain name lookup, and, since my hostname was set to
localhost, resulted in 127.0.0.1, which is the IP for any computer.
The CVSup server realizes this, and declines my connection.

Now, my questions are:
(a) Is this what is really happening?
(b) If so, how do I get CVSup to get my IP that was assigned
dynamically?
(c) If not, what is the remedy to this situation?

Thanks in advance,
