IP address for the PABX:

192.168.1.250

Subnet mask:

255.255.255.0

Start address DHCP:

192.168.1.50

Number of DHCP addresses:

20

PC1

IP via DHCP:

192.168.1.50 transmitted automatically via DHCP.

Gateway:

transmitted automatically via DHCP.

DNS server:

transmitted automatically via DHCP.

Subnet mask:

transmitted automatically via DHCP.

PC2

IP via DHCP:

192.168.1.53 transmitted automatically via DHCP.

Gateway:

transmitted automatically via DHCP.

DNS server:

transmitted automatically via DHCP.

Subnet mask:

transmitted automatically via DHCP.

In the example given here, the IP addresses for the clients (PCs) can lie within a range from IP 192. 168. 1. 50 to 192.

168. 1. 69. The IP addresses are assigned in the order that the clients (PCs) request them (for example by switching on

the PCs). If an IP address is released (for example by switching off a PC) that IP address is then available to be

re-assigned again.

Address assignment without DHCP  (set / mixed IP addresses)

You can dispense with a DHCP server in a network or also configure LAN clients (PCs) with set IP addresses as an ad-
dition to the DHCP clients.

Note
Much more time and effort is involved for configuring the network if a configuration is chosen without DHCP. If

Address assignment by DHCP -Recommended configuration - (Default setting) Configuration examples
