The client connection diagram on page 174 lists IP responses from DNS for two domains, but the follow up request for the respective domain calls to a different IP:
- The first shipping.example.com query responds with 10.1.1.142, but the diagram shows the subsequent call to 10.1.1.141
- The second shipping.example.com query responds with 10.1.1.143, but the diagram shows the the subsequent call to 10.1.1.142
The DNS responses do not match where the “GET /rates” calls ultimate send their requests.
