how we can get list of connected IP in LAN using C#

Are you trying to get the IPs for a specific service, all services?

Hi discord
I am trying to get IP's and associated User Name so that i can display them on my chat messanger...but i am not maintaining user database and am using udp protocol for data exchange using C#
Whenever tool is run it asks for temporary user name and associates it with the System IP.Then common chat room is displayed where in we can see all connected Users(with temp user names and there system IP's).
I need help to get these list of users on each connected system so that every user can see users available on LAN.
i tried following code
IPAddress[] ips = Dns.GetHostAddresses(Dns.GetHostName());
but of no use..
Please Help

I am establishing P2P connection...

The users you are trying to get a list of, how are they connecting? If it is the users on your own program, you should be getting that info and persisting a list of users and IPs that connect to it when you receive a UDP packet. Since UDP is connectionless, your protocol for you tool, may need to send the IP and User name every time in the UDP data.
