DNSQuerySniffer
Display your PC's DNS queries in real time

DNSQuerySniffer is a tiny (130KB, including a Help file) network sniffer which detects and displays DNS queries as they're sent on your system.

This has some security applications. Malware will often use DNS traffic to communicate with its operators, for instance, so taking a closer look at your own system might help to uncover an infection (look for odd or unusual domains, say, or a lot of failed lookups).

And more generally, DNSQuerySniffer helps to reveal which of your applications is trying to go online, and maybe what they're trying to do.

The data capture itself can be done via WinPcap and Microsoft Network Monitor. Or if you'd rather not install anything else, choose the "Raw Sockets" option and you may still get reasonable results (the documentation provided with DNSQuerySniffer explains more).

Any queries intercepted are displayed in full, with all the details you'd expect: Host Name, Port Number, Query ID, Request Type, Request Time, Response Time, Duration, Response Code, Records Count, and the returned records.

And as usual with NirSoft tools, everything is displayed in a sortable table, and your data can be exported as TXT, CSV, HTML and more.

Version 1.50 adds:

- Added 4 columns to the adapters list in the 'Capture Options' window: 'Connection Name', 'MAC Address', 'Instance ID', 'Interface Guid'.
- When using WinPCap driver , DNSQuerySniffer now displays more accurate information in the adapters list of the 'Capture Options' window.

Verdict:

It's probably not a tool you'll use every day, but DNSQuerySniffer can occasionally be useful as a simple way to watch your PC's DNS traffic

WhatsApp Messenger 2.12.13

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.
