named instance and default instance: same port

When one install a named instance in addition to a default instance on the
same server, does the named instance also get assigned to the same port 1433
? ThanksNamed instances dynamically assign an unused TCP port number the first time
the instance is started. You can use the server network utility to see the
port number you've got. BTW, there is a listener service which runs on UDP
port 1434 but doesn't have a service name on the
machine. This listener service exposes which SQL Server instances are
installed, and their associated port numbers.
