If you think of your local network as a neighborhood, a network address is analogous to a house number. Using Wireshark, you can watch network traffic in real-time, and look inside to see what data is moving across the wire.Īn IP address is a unique identifier used to route traffic on the network layer of the OSI model. It works below the packet level, capturing individual frames and presenting them to the user for inspection. Wireshark is a network monitor and analyzer. Here’s how I use Wireshark to find the IP address of an unknown host on my LAN. But it can also be used to help you discover and monitor unknown hosts, pull their IP addresses, and even learn a little about the device itself. However, if you know the UDP or TCP or port used (see above), you can filter on that one.Wireshark is a powerful tool that can analyze traffic between hosts on your network. You cannot directly filter SIP protocols while capturing.

XXX - add a brief description of SIP history Protocol dependencies The SIP protocol is a member of the VOIPProtocolFamily. SIP can create, modify, and terminate sessions with one or more participants.
These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for sessions.
