A static IP offering actually has two WAN addresses. The first address is the address
assigned by NOC for the DWx000. This is the LAN gateway address. The second address
assigned by NOC is 1 address increment above the DWx000 – the static host address on
the installation’s LAN. For example,
DW6000 IP address: 67.46.28.1 (LAN gateway address)
First host on LAN: 67.46.28.2 (This will be a single PC or a host)
Subnet mask: 255.255.255.252
In a non-residental installation the DWx000 functions like a cable/DSL Network
Termination Interface (NTI) or “modem” as they refer to it. As such the user will have to
acquire a separate router to service the LAN for NAT, DHCP, and firewall functions.
The subnet mask would hint that more than one static address could be used. In fact the
business offerings have (5) additional static IP addresses available at an additional
monthly charge. The DWx000 DHCP would hand out the static IP addresses to the first
hosts that requested them. This could be used to set up a DMZ.
Dial backup is offered in all plans except the residential plan. For such plans the DWx000
is exchanged for a DW6002. The DW6002 has an additional telephone POTS RJ11 port
on the rear panel.
When selecting rate plans remember that for every 1Mbps of network traffic a PC has to
process roughly requires 1Ghz of its processing cycles. To truly process 100Mbps would
require 100Ghz of dedicated on board processing. It is easy to over size the network to
what is actually required. Use of switches instead of hubs, or proxy servers instead of the
broadband connection can have greater performance gains than installing CAT6 wiring
instead of CAT5e.
