A user on the host 170.210.17.145 is using a Web browser to visit www.example.com.

In order to resolve the “www.example.com” domain to an IP address, a query is sent to an authoritative name server for the “example.com” domain. In response, the name server returns a list of four IP addresses in the following order {192.168.0.1, 128.0.0.1, 200.47.57.1, 170.210.10.130}. Even though it is the last IP address in the list returned by the name server, the Web browser creates a connection to 170.210.17.130. Why?
