allocates different range for user-space applications. For linux its

Hum, that's not entirely clear to me. The first link says...
'A TCP/IPv4 connection consists of two endpoints, and each endpoint
consists of an IP address and a port number. Therefore, when a client user
connects to a server computer, an established connection can be thought of
as the 4-tuple

You need ephemeral ports so a server can start listening on port 22 again
while something else is happening.
Look here for some configuration options.
We are using SSHD in an application to create an embedded SFTP server which
