TIP on SQL Server Profiler Trace

I was trying to find out who/ what application are connecting to  SQL SERVER  "ITSQL"

Instance Name:"ITSQL"

IP Address: "172.00.00.00"

Say, 

Application XYZ connecting to  SQL SERVER with Instance Name:"ITSQL "

and 

Application ABC  or someone else connecting to  SQL SERVER with IP Address: "172.00.00.00"

when i try to run Trace with below template 

EventClass ApplicationName LoginName SPID Starttime Database HostName SessionLoginName ServerName

i was not able to find out application which are connecting to SQL SERVER with IP Address: "172.00.00.00"

so after a lot of testing i found that even when ABC application is trying to connect with IP address  "172.00.00.00" , it shows as connecting to Instance name "ITSQL"

So, i was able to find out all connections..

Fyi...this is not proven yet in production..
