If a client wants to connect to an address such as ‘ External link icon Open external link and needs to know which IP address corresponds to this address, they can ask DNS.

The concept of DNS is simple: it’s a global database of information about domain names. As the mechanism that maps domain names to Internet Protocol (IP) addresses, it provides a human-readable layer to navigate the millions of machines and devices on the Internet.

The Domain Name System (DNS) is one of the oldest and most fundamental components of the modern Internet. The following description of DNS is lifted from Nick's External link icon Open external link blog post: DNSSEC: An Introduction External link icon Open external link. This integration is much easier than the previous one.Before you can open a connection with any application, you first need to know where to find that application - aka its IP address. Acrylic Wi-Fi Sniffer and WiFi interfaces in Wireshark If you want to know more about capture modes or discover the features that these two alternatives provide within Acrylic Wi-Fi products, please visit “Monitor mode and native capture mode in Acrylic Wi-Fi” article. Because it has been designed as an economical and easily configurable alternative to AirPCAP hardware, it can capture all data available with this type of card, including SNR values, and is compatible with the latest 802.11ac standard in all channel widths (20, 40, 80 and 160 MHz). Acrylic Wi-Fi SnifferĪcrylic Wi-Fi Sniffer also enables Wi-Fi packet capture in monitor mode with Wireshark on Windows (in the latest versions Wireshark 3.0.0 or higher) and with other Acrylic Wi-Fi products such as Heatmaps or Professional. However these cards have been discontinued and are deprecated, so they cannot capture traffic on networks running the latest WiFi standards (802.11ac).Īcrylic Wi-Fi Sniffer is an innovative alternative for capturing Wi-Fi traffic in monitor mode from Windows, including the latest 802.11ac standard. In other words, it allows capturing WiFi network traffic in promiscuous mode on a WiFi network. However, Wireshark includes Airpcap support, a special -and costly- set of WiFi hardware that supports WiFi traffic monitoring in monitor mode. Winpcap Capture Limitations and WiFi traffic on WiresharkĬapture is mostly limited by Winpcap and not by Wireshark. Monitor mode for Windows using Wireshark is not supported by default. Winpcap libraries are not intended to work with WiFi network cards, therefore they do not support WiFi network traffic capturing using Wireshark on Windows. Wireshark uses libpcap or Winpcap libraries to capture network traffic on Windows.
