Start Chrome and start Wireshark. Apply the filter udp.port==5355

For Link Local Multicast Name Resolution protocol (LLMNR) protocol you
will similar output in wireshark.

This protocol was implemented Windows Vista onwards, so you should
this in Windows Server 2008 and Windows 7 as well.

Interesting I will have to test this one and see. I know recently someone did a writeup about Microsoft doing a 
similar phone home when you launch I.E  so it can verify you internet connection.

Subject: [Full-disclosure] Google chrome sending strange DNS queries

Greetings,

Has anyone ever noticed, the sort of DNS queries when you fire/running
Google-chrome?
The DNS queries for domain names likes:
bsjghxplor
hrrtjswxtt
epjyptuure

etc.

Behavior has been observed on Linux as well as Windows systems.
See the attached screenshot of wireshark dump.
