www[2-6].google.com

I am new to this stuff. This might be a simple fact. But, I am trying to understand some naming conventions used for servers.

www[2-6].google.com

The following domains redirect to www.google.

www2.google.com
www3.google.com
www4.google.com
www5.google.com
www6.google.com

1. Does gfe have any special meaning in
gfe.core.l.google.com

Also, I have heard about google fresh bot and google deep bot.
64.68.82.x - indicates freshbot
216.239.46.x - indicates deepbot

Observing the IPs of the bot may give information about google crawling strategy. :P
