What is DNS? Introduction to Domain Name System. SXSW giveaway!

I've been running a DNS resolver on my pfSense firewall/router for about 7.5 years. Prior to that, I was running DNSmasq on a Linux firewall/router for several years.

BTW, to make better use of your monitor space, you might want to run Wireshark in the 2nd layout, with panel 1 across the top and panels 2 & 3 at the bottom, with panel 3 just wide enough to display the hex data.

53 ports we will use for dbs

Very useful video! Seeing how this process is captured on wireshark clarified the whole process for me. Thank you.

Great video, thank you! I really need to get GNS3 one of these days. It looks so much more robust than packet tracer.

not for laymen. Too fast for me. I feel like a chameleon on a smartie box. But thank you, i think. I understood the 1st 2 minutes.
