How To Get IPs Over Skype

This is a quick tutorial on how to get IPs on someone over skype.
This can be useful if someone scammed you or something.

Things you'll need:
Skype (Obviously)
WireShark (Or traffic monitor of your choise.

Any OS supported by Skype (even android, over WiFi only)

First you need to understand, the more active things are on you Skype; people trying to call you, getting status from contacts, and conversations will all give you a large amount of traffic.
(I personally recommend using a temp skype account for doing stuff like this.)

And we will be monitoring packets, not IP lists like network connections will normally provide, this way you have a better chance of finding the correct IP.

Getting Started

First open up Skype and go to Tools > Options
Now click the Advanced tab and go to Connection

Un-mark and disable the option "use port 80 and 443 as alternatives for incoming connections"
Now take note of the port set in "use port XXXX for incoming connections" for this example we will use port 21625.

Save & Restart Skype.

Second Step open WireShark, pick the Interface you use to connect to the internet and pick Start.

You will probably see alot of results. We need to clean this up a bit with the Filter.

First get your local IP, you can do this in windows by starting command prompt Run > CMD
And in command prompt typing the following "ipconfig" (without quotes).

Now take Note of your Local IPv4 Address for the interface you are using,
In this example it will be

Now back to WireShark to filter everything only the things going from Your PC on port 21625 and only UDP.

In the filter box type;
ip.src == and udp.srcport == 21625
Now hit Apply and you should only see Skype traffic from your PC

Most of the resaults are from the skyp servers but to make it even more accurate add:
"and data.len == 3"

This narrows it down to packets of 3 bytes (most of the packets this small are p2p)

So now it the filter says;

ip.src == and udp.srcport == 21625 and data.len == 3

As you can see the IP of the person you are calling is in the "Destination" and you are the Source.

Now it should be very easy for you to spot someones IP when you call them or they send you are in a call or get sent a message.
