This week Tweeks helps fill in by reviewing Brigante challenges 14-15 and getting into 16 and assigning homework of doing up through challenge 19. Then we switched over to doing more of our Networking challenges touching on how DNS translates FQDNs (Fully Qualified Domain Names) into IP addresses, touched on DNS record types (and how to query them), talk about how MAC hardware addresses are used on LANs (vs Internet IPs), and then do some more advanced file carving using Wireshark. We didn't complete the "Shades of the Blues" Networking challenge, but are going to solve that one as a homework assignment, and come back at our next meeting to show the solution.
