Major Intel.com Spidering Activity - Multiple IP's

On the other hand, I've been seeing regular traffic from the employees at Intel, with those ip addresses for the last 2 years. From the search terms, I can tell that they are surfing while working from the complex across town from me (Portland, OR).

134.134.136.1-5 and 14.

So this must be something completely new.

It's a proxy, that much I know for sure:

134.134.136.2 Via Proxy: 1.0 jffwpr02.jf.intel.com:911 (squid/2.5.STABLE12)

So it's probably mixed traffic.

Whatever was on my site answered the captcha.

CHALLENGE 134.134.136.2 "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1)"

RESPONSE 134.134.136.2 "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; InfoPath.1)"

Didn't ask for very many pages either.
