You can install wireshark and have it sniff the network traffic.

Active ports is a small utility that works pretty well for single use type situations.

Use a packet-sniffer to view and capture the data. SmartSniff is one of the easiest to use.

You can see the associated domain name by checking the Resolve IP Addresses—which is enabled by default.
