Dynamic port range means ports reserved by the operating system. This range is assigned by the Internet Assigned Numbered Authority (IANA). Applications may not hardcode any port in dynamic port range(s). There was one such range priori to Windows Vista and Windows Server 2008; one more range has been added for the mentioned OS.
The default dynamic port range is 1024 through 5000 (for Windows 2003 and earlier types). For WIndows Vista and Windows Server 2008 the range 49152 through 65535 has also been reserved.
Netsh command-line utility may be used to view or change the dynamic port range.
To display the range, use the following command:
netsh int, [ipv4|ipv6] show dynamicport [udp|tcp]
To change the range, issue a command like
netsh int, [ipv4|ipv6] set dynamicport [tcp|udp] start=NNNNN num=MMMMM
The string in brackets, separated by vertical line mean 'use either of the string'.
