How do you obtain a registered IP Address?

The IP registration system ensures that every IP address used is unique; if

you do not have a registered IP address, you may be using an identical

address to someone else and your network will not operate correctly.

InterNIC Registration Services is the organization responsible for

supplying registered IP addresses. The following contact information is

correct at time of publication:

World Wide Web site: http://www.internic.net

If your IP network is internal to your organization only, that is, you do not

access the Internet, you may use any arbitrary IP address as long as it is

not being used by another device on your network. 3Com suggests you

use addresses in the series 192.160.100.X (where X is a number between

1 and 254) with a subnet mask of 255.255.255.0.

These suggested IP addresses are part of a group of IP addresses that

have been set aside specially for use ‘in house’ only.

Solving Stack

If you are having problems with correctly forming a stack, first ensure that

Formation

Spanning Tree is enabled. If it is enabled, do the following:
