How to Identify port number of SQL server

Question

I Install SQL server in my system and I have to check on which port number SQL is working in my system

Answer 1

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

Answer 7

PowerShell solution that shows all of the instances on the host as well as their incoming traffic addresses. The second bit might be helpful if all you know is the DNS:

ForEach ($SQL_Proc in Get-Process | Select-Object -Property ProcessName, Id | Where-Object {$_.ProcessName -like "*SQL*"})
{
    Get-NetTCPConnection | `
     Where-Object {$_.OwningProcess -eq $SQL_Proc.id} | `
      Select-Object -Property `
                                @{Label ="Process_Name";e={$SQL_Proc.ProcessName}}, `
                                @{Label ="Local_Address";e={$_.LocalAddress + ":" + $_.LocalPort }},  `
                                @{Label ="Remote_Address";e={$_.RemoteAddress + ":" + $_.RemotePort}}, State | `
      Format-Table
}
