DNSQuerySniffer is a lightweight network utility which detects and displays DNS queries sent from your system. The program provides an extensive information about each DNS query such as host name, port number, number of records, response time & duration, query ID, response code, request type and content of the returned DNS records.
The networking tool lets you export the details of queries to HTML, CSV or tab-delimited XML file. You can also copy these queries to the clipboard and then paste them into any spreadsheet application like Excel.
The network sniffer monitors all DNS queries sent by your computer to outside resources. In other words, users are able to view IP addresses of the connected servers or websites to your system. Download DNSQuerySniffer to keep a track of all outgoing information from your system.
The utility uses three options for data capturing: Raw Sockets, Microsoft Network Monitor and WinPcap Packet Capture Driver. However, to use capture driver, you may need to install it separately. The software allows you to select capture method and desired network adapter. Then, it automatically starts capturing packets along with your selected capture method and network adapter.
You can pause or resume the data capturing process anytime. The network monitoring service can be used to examine for DNS propagation, which basically occurs whenever a website transfers between two servers. It also can be used to keep an eye on your visited websites.
