<h1>Addresses</h1>
When you select the Addresses tab in the main window, DHCP Manager displays the
client records in the selected network, sorted by host name. These records are stored in the DHCP network tables maintained by the data store.<P>
<STRONG>List Addresses</STRONG><BR>
To view the records sorted by IP address, click Show Address in
the View menu. Servers and clients are listed by IP address instead of by host name.<P>
<STRONG>Change Sort</STRONG><BR>
The client records are sorted by client
IP address or host name. To change the sort, click
in the column header. For example, click the Server
column heading to view the records alphabetically in ascending
order by server name. Hold down the Shift key and click the
Server column heading to view the records listed by server
in descending order.
<P>
<STRONG>Add Address</STRONG><BR>
To add new addresses to the selected network, choose <a
href="dhcp_addr_wiz.html">the Address Wizard</a> from the Edit menu.
You can add a single address by selecting
<STRONG>Modify Address</STRONG><BR>
You can select an address and view the settings assigned to that address,
href="dhcp_addr_how.html#reladdr">release</A> or <A HREF="dhcp_addr_how.html#deltable">delete</a> addresses in the list.

<td valign="top">A unique indentifier of the DHCP or BOOTP client using this address. The client ID is determined by the vendor of the DHCP client. For non-Solaris DHCP clients, consult your DHCP client documentation for more information.<P> For Solaris DHCP clients, the client ID is a string created by the concatenation of the network hardware type and the client's hardware address. For example, a client with a hardware type of <tt>01</tt> (10-Mb Ethernet) and a hardware address of <tt>8:0:20:11:12:b7</tt> would have a client ID of <tt>010800201112B7</tt>.
<p>
An entry with a Client ID value of 00 indicates that the address is
freely available for dynamic allocation to a requesting client.
