Appendix B: Concepts 

The IPNC’s mode of operation for the DHCP Server is configured in the System 
Configuration form box. 

With Server selected, IP addresses are allocated both to the LAN using DHCP 
and to dial in users during PPP link establishment. With Dial-In selected IP 
addresses are allocated only to dial in users 

Dial– In users are allocated address from the LAN1 pool until all addresses are 
exhausted, at which point addresses from the LAN2 pool will be used. 

Router 

System- IP Address (for LAN1) 
System – IP Address 100Mbps (for LAN2)

Notes:   1.  The IPNC uses its system address+1 for the first IP address 

allocation (i.e. System IP address is 192.168.42.1 then the first IP 
address will be 192.168.42.2). 
For dial in uses the IPNC allocates the top address as governed by 
the number set in the Number Of Address on the System 
Configuration DHCP tab. (i.e. System IP address is 192.168.42.1 
and Number Of Address is 200 then the first IP address will be 
192.168.42.200) 

2.  The IPNC offers either the LAN 1 or LAN2 IP address as the router 

dependant on which interfaces the request is made from. 

 

3  This is typically the IP address of an external DNS Server. If this is 

left blank, the IPNC will offer itself as a DNS server (within DHCP) 
and will forward DNS requests. The IPNC forward DNS request to 
the IP address of the DNS server learned in PPP link establishment. 
This option is controlled in the Service Configuration.
