Figure 50. Transparent Subnetting Twinax Scenario with Class C TCP/IP Address
Figure 51. Transparent Subnetting Class C Address Example
The Local LAN has a network address of 192.168.1.0 and a mask of
255.255.255.0. This mask gives you the entire range of addresses to use in
the last byte or octet of the address. As in our next scenario, we are using a
DHCP configuration here to break up this entire range using masks. As
shown in Figure 51, the
Local LAN is configured to have a range of address
from .1 to .191 (boundary address cannot be used). The remainder of the
address space is reserved for different subnets.
The next group of addresses,
Tw x1 , has a subnet address of 192.168.1.192
and a mask of 255.255.255.224. This mask gives you eight groups of 32
contiguous addresses (refer to Figure 17). Only the block containing the
range of addresses from 193 through 222 is used. Remembering that
