How can I list all active and unique ips connections in a IIS server

I'm trying list all active connections in an IIS Server and i don´t know how to make this happen. I'm studying about some methods and trying to make a script in Powershell which extracts a number of all connections in an specific port (like 80 port) and a number of unique connections in a specific port (like 80 port).

I need this information because in some cases I have multiple access to this server based on the same IP, so I need filter this IPs access and look two numbers, one which show all active connections and another which show all unique connections.

Thanks for the help!!

Solution

Solved!

Instead of using netstat commands, i´ve used the Get-NetTCPConnection resource, based on these articles.

So, i filtered all connections established in the port 80 and group by the foreign address (named as RemoteAddress).

$count_unique_ips = Get-NetTCPConnection -LocalPort 80 -State Established | group RemoteAddress -NoElement
$count_unique_ips.count

And based on that link I've solved the problem of list all connections in port 80.

$c = netstat –aon | findstr ":80" | select-string “ESTABLISHED” ;
$c.count
