This is a potentially very useful tool/feature that I will be testing further in the weeks to come.

I am now using the loopback adapter to capture traffic that I source into a Dyanmips/Dynagen virtual router network. ipconfig /all and look at the MAC-ID for your new adapter.Д¤. Recipe (to capture traffic on ms loopback adapter / Windows XP): - by mitra 1.

The only benefit I can see so far is if you use it with colinux (and probably other PC virtualization software) to capture the traffic between Windows and the virtual machine.

If you ping on 10.0.0.11, you won't get ping replies as there is obviously no remote host, but you will see the corresponding ARP requests in Wireshark. If you ping to this 10.0.0.10 address the ping will get ping replies, but you won't see any of this traffic in Wireshark (much like the 127.0.0.1 problem). Let's suppose you have set the IP address of the loopback adapter to 10.0.0.10 and are capturing on that interface. BTW: You can only add one Loopback Adapter to the system!Д«eware: Capturing from this Loopback Adapter requires the WinPcap 3.1 release, 3.1 beta versions won't work! This adapter is a virtual network adapter you can add, but it will not work on the 127.0.0.1 IP addresses it will take its own IP address. вЂ¦ and is quite different than the ones available for various UN*X systems.

Microsoft: How To Install Microsoft Loopback Adapter in Windows 2000 Microsoft: How to install the Microsoft Loopback adapter in Windows XP Microsoft: How to install the Microsoft Loopback Adapter in Microsoft Windows Server 2003 This adapter is available from Microsoft: You can add a virtual network card called Microsoft Loopback Adapter, but in most cases that might not give results as expected either. You can, however, use a raw socket sniffer like RawCap to capture localhost network traffic in Windows. The following page from 'Windows network services internals' explains why: The missing network loopback interface.

#Loopback address driver

You can't capture on the local loopback address 127.0.0.1 with a Windows packet capture driver like WinPcap. Starting from Wireshark 1.12.8 and 1.99.9, the Windows installer will detect Npcap presence (when installed in WinPcap compatible mode) and will not try to install WinPcap 4.1.3.

#Loopback address code

The current latest installer can be found here:, the source code can be found here: When installed on Windows XP or earlier, it will install the legacy WinPcap driver. When installed on Windows Vista or later (including Win7, Win8 and Win10) with option 'Support loopback traffic ('Npcap Loopback Adapter' will be created)' selected, it will create an Npcap Loopback Adapter that can be selected in Wireshark so as to capture IPv4/IPv6 loopback traffic. 1) NDIS 6 SupportД¤) Loopback Packets Capture and Send Support (either as fake Ethernet or Null/Loopback frames)ДҐ) Raw 802.11 packets Capture Support (in 'monitor mode') Npcap has added many features compared to the legacy WinPcap.

#Loopback address update

Npcap is an update of WinPcap using NDIS 6 Light-Weight Filter (LWF), done by Yang Luo for Nmap project during Google Summer of Code 20. Windows Starting from Windows Vista: Npcap Summary: you can capture on the loopback interface on Linux, on various BSDs including macOS, and on Digital/Tru64 UNIX, and you might be able to do it on Irix and AIX, but you definitely cannot do so on Solaris, HP-UX, or Windows. See CaptureSetup/NetworkMedia for Wireshark capturing support on various platforms. You will only see it if you capture on the 'loopback interface', if there is such an interface and it is possible to capture on it see the next section for information on the platforms on which you can capture on the 'loopback interface'. This means that you will not see it if you are trying to capture on, for example, the interface device for the adapter to which the destination address is assigned. If you are trying to capture traffic from a machine to itself, that traffic will not be sent over a real network interface, even if it's being sent to an address on one of the machine's network adapters. The following will explain capturing on loopback interfaces a bit.
