Michael - that street address is an office building occupied at least in part by ISI, a research outfit closely related to the USC School of Engineering Depts of Comp Sci & EE. They've been very closely involved with development of Arpanet & the internet since the beginning. You might nose around <http://www.isi.edu>, and even place a phone call to their front office in Suite 1001 if you're really concerned.
