IP8(DMZ host4)
unrestricted 2-way communication capability.
Most likely the multiple DMZ host are applied in router-to-
router inter-connection SOHO environment (please refer to
Figure 4-2). Home user is less popular due to the
range of
WAN IP address”. Because IP address is another important
and expensive resources at present.
Some ISP provides leased line service (DSL is more
common) to subscribers, meanwhile could offer a range of IP
address for subscription. In this case, there are two type of
connection configuration. One is Bridging mode, the other is
Routing mode.
For example, the ISP provides 210.65.226.0 ~ 7 IP range
(subnet mask is 255.255.255.248), then subscriber could
have 5 computers at most to access Internet simultaneously.
Surely additional computers are also able to access Internet
via Broadband Router. (Please refer to Figure 4-1)
