You really should do one of two things.&lt;/p&gt;

&lt;p&gt;
Either use a fixed IP (stored in a flash sector or EEPROM and
reconfigurable through some menu command). But with a fixed IP
number, you shouldn&amp;#39;t hae to change it from 192.168.0.100 to
192.168.0.2. With a fixed IP number, it would most probably be ok to
reboot your unit after a reconfiguration to let the new IP number be
used.&lt;/p&gt;

&lt;p&gt;
Or you should use a dynamically assigned IP number, in which case
you should make use of DHCP. With most DHCP servers, you can even
enter the MAC address of the unit into the DHCP server configuration,
allowing the server to always recognize your unit and giving it a
fixed IP number.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: problem with ethernet and ip</title><link>https://community.arm.com/thread/115972?ContentTypeID=1</link><pubDate>Sat, 21 Aug 2010 04:51:23 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:fe284871-ed58-41e4-aa8f-0349892742aa</guid><dc:creator>deepika rai</dc:creator><description>&lt;p&gt;&lt;p&gt;
