SQL SERVER – Network Protocol and IP Address

Today we are going to look at a very simple query my client asked me during a recent Comprehensive Database Performance Health Check. The question was if there is a way to know how many sessions are connected to current SQL Server instance with their network protocol as well as IP address. Absolutely, SQL Server is pretty good at surfacing such information. Here is the script.

SQL SERVER - Network Protocol and IP Address networkprotocol-800x542

Script for Network Protocol

SELECT
c.session_id, c.net_transport,
c.client_net_address,
s.host_name, s.program_name,
s.login_name,
c.connect_time,
s.login_time
FROM sys.dm_exec_connections AS c
JOIN sys.dm_exec_sessions AS s
ON c.session_id = s.session_id 

When you run the query above it will give you a result like the following image.

On that screen, you can see various details related to IP address as well as the application which is connecting the SQL Server instance.
