Brett Lykins

Hello!

I've been working in Networking since 2007 in roles ranging from frontline Internet Helpdesk tech to Network Architect. I'm currently a Network Security Architect at Rackspace Hosting.

I enjoy digging into a little bit of everything: Cisco VoIP, Enterprise Routing/Switching, WANs and VPNs, Wireless, Data Center switching, Firewalls, Load Balancers, and more.

My (poor, neglected) blog is at network-notes.com.
