IP address for cco.caltech.edu

[ZCEL02@TULATCPA.amoco.com (Charles Lott)]

Where can I get the IP address (xxx.xxx.xx.xx) for cco.caltech.edu?

I've just discovered that the way I'm trying to FTP to sites around
the internet that have apple2 files is not working because the IP
addresses are not available for many systems (I'm thinking that the
"directory" of systems around the internet is not being updated).

At any rate, if you know the IP address for cco.caltech.edu, PLEASE
let me know ASAP.  Thanks.
