TCP/IP Stack - Max. number of connections: 11000?

Hello Community,

I'm wondering what exactly means that limitation of 11000 connections in ESXi default TCP/IP Stack.

Is that a limitation of all connections for the entire Host?

Due to the fact that VMs don't use kernel Ports, is there another limitation for VMs max number of connections, just like a limits.conf file or something like that?

thanks for any help to clarify that.
