20.1.1 DHCP-Server (Dynamic Host Configuration Protocol)
A DHCP server should be used for distributing unique IP addresses to the telephony clients. The following clients are suitable for this:
SwyxPhone L6xx
SwyxIt! Classic (not from Windows Vista on)
The DHCP server is a component of the Windows Server operating system and it offers the following advantages:
Unique and specific assignment of IP addresses
Automatic transmission of the SwyxServer IP address to the telephony clients
The DHCP server offers you the option forwarding changes to the IP address of the client directly to the DNS server. This is important in order to keep the assignment of the IP address to FQDN (Fully Qualified Domain Name) of the computer consistent.
If there is no DHCP server in the network, install a DHCP server on the SwyxServer computer.
How to install a DHCP server
1 Click on "Start | Settings | Control Panel."
2 Double click on "Software" and then select "Add/Remove Windows Components".

8 The Windows DHCP server is installed and is then available to you.
The DHCP server offers you the option forwarding changes to the client IP address directly to the DNS server. This is important in order to keep the assignment of the IP address to FQDN (Fully Qualified Domain Name) of the computer consistent.
This is how you configure the DHCP server for dynamic update
1 Start the DHCP Administration in Windows under "Start | Administration".
2 Click with the right mouse button on the server and select "Properties".
3 Click on the "DNS" tab.
4 Activate the checkbox "Automatically update DHCP client information in DNS".
In order for the Windows client computers to receive the IP address of the WINS and DNS servers, these must be entered on the DHCP server as DHCP options:
006 DNS Server
044 WINS/NBNS Server
Please note that the query of server information via DHCP is only possible for clients with Windows2000 or later.
