Query strings are data strings following the '? ' delimiter in urls often used by webform submissions and search engines. Query strings may contain sensitive information such as credit card numbers, passwords, names, addresses, hotel/flight reservation details and other personally identifiable information which an unethical browser extension could monitor and retransmit to its home server or a third party. Firewalls won't block browser extensions because they're integrated into the web browser. Browser toolbars can sometimes be removed by using the Windows Add/Remove Programs utility or by running the toolbar's uninstaller which should be packaged with it. Before removing an adware toolbar you may like to take notes and screenshots of the companies being advertised in its links, search listings or pop-up ads.

If you omit the netmask ipcalc uses the default netmask for the class of your network. Look at the space between the bits of the addresses: The bits before it are the network part of the address, the bits after it are the host part.
