I own a small, successful security consulting business. But by day I work for a really big company, doing really big things.

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

.com and .net are both verisign. They're the exception. en.m.wikipedia.org/wiki/Verisign

@JennyD yes, there are several projects out there like that. But I'm building one that hopefully gives better detail and is easier to understand. But thanks for pointing that one out.

@HåkanLindqvist I'm actually building a tool that looks for problems in DNS configurations. This is one the of the problems to look for. The question is, how deep should the system recurse to look for further problems before just giving up.

comment Unable to install phpMyAdmin via yum (remi)
Looks like the package or dependency is broken. Why don't you just download it from source? The package doesn't provide any useful that the vendor's tar.gz does not. Also, use Adminer instead of PMA. Faster, simpler, safer.

comment Are Cisco admins expected to understand classful networks?
I'm just saying that the terminology is popular with a very, very, very small subset of the industry. And completely coincidentally, they all seem to be Cisco Certified Engineers.

"Class C" isn't any more clear than "/24". You have to learn /24 anyway, so calling it "Class C" just serves to confuse people who aren't familiar with the terminology while at the same time making yourself look uninformed to people who are. It's a bit like referring to the "OSI model of TLS encryption" -- that is, (A) most people don't even know what the OSI model is, and (B) apparently neither do you.

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?
