Known Port Numbers<br />
In this appendix, which is included for your reference, we provide a list of Well Known port<br />
numbers that may cause network problems if you set <strong>NPort</strong> <strong>5110</strong> to one of these ports. Refer to<br />
RFC 1700 for Well Known port numbers, or refer to the following introduction from the IANA.<br />
The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports,<br />
and the Dynamic and/or Private Ports.<br />
The Well Known Ports range from 0 through 1023.<br />
The Registered Ports range from 1024 through 49151.<br />
The Dynamic and/or Private Ports range from 49152 through 65535.<br />
The Well Known Ports are assigned by the IANA, and on most systems, can only be used by<br />
system processes or by programs executed by privileged users. The following table shows famous<br />
port numbers among the well-known port numbers. For more details, please visit the IANA<br />
