Long-time owner and operator of a small, successful security consulting business. As of recently, though, by day I work for a really big company.

Nothing I write here represents the views of my employer, nor does it reflect any proprietary or confidential knowledge. In fact, practically all of it was written before I even started working there, so don't get too excited.

comment Are Cisco admins expected to understand classful networks?
The fact the CCENT uses A/B/C as shorthand for /8 /16 and /24 measurably diminishes the credibility of the certification in my book. Would you trust a pilot if the pilot's exam questions he answered used the word "handlebars" to refer to the control yoke or "railyard" to mean "airport"? Should you be allowed to write exam quiestions if you don't understand your own industry?
