6.7a - Recursive DNS Query - Minor Error
I thought I would highlight that on slide 6.7.a - "Recursive DNS Query", Line 8 states "The caching nameserver makes a query for host1.foo.example.com to the nameservers for the foo.example.com.." I do believe that this is supposed to have the word "zone" at the end, i.e. "to the nameservers for the foo.example.com. domain.", which is further evidenced by the presence of two periods at the end. Thanks for listening, and have a good day!
