Network in my Veins

Today I am CCNA certified, not to mention i already hold MCSD in .NET. This marks the beginning of me being an overly qualified nerd, after trying my hands on every possible technology in programming domain and writing all kind of software applications, where is the peace? I think this started a few yrs back when i wrote my first integration application. Handling data streams over the network was a good change over writing conventional database applications; so much so that i moved my focus to network traffic; stating with Citrix and how IPs are NATted across domains, how firewalls collide with router based access lists; to managing the data center with machines as old as IBM 330s to new HS21 Blade severs; i think am getting the much needed kick out of it.
