Project Two: Network Diagram and Rationale Southern New Hampshire University CYB-210 02:14:40 GMT -05:00 Dear Network Administrator, I combined Subnet1 (192.168.1.0) and Subnet2 (192.168.5.0) into a single NetworkA (192.168.1.0/24). I did this by connecting all hosts on one switch and configu...
I combined Subnet1 (192.168.1.0) and Subnet2 (192.168.5.0) into a single NetworkA
(192.168.1.0/24). I did this by connecting all hosts on one switch and configured a new set of IP
addresses for each host on the 192.168.1.0/24 network. The 192.0.0.0 range is a Class C classful
range and uses the subnet mask of 255.255.255.0, giving us 256 potential hosts for the network
which should be plenty in this scenario with room for future expansion. I was also able to get rid
of the switch that Subnet2 was using since all the hosts are connected to a single switch. I also
configured a DHCP server for Network3 (192.168.11.0/24) that supplies each host on the
network with an IP address automatically via the server. The DHCP service currently has a
maximum of 50 hosts, which should be plenty for now. As we add more nodes to Network3
they too will automatically be supplied with an IP address via DHCP, making the setup of
additional hosts very simple.
Additionally, I added another router to the Network3 infrastructure and added a static
route to NetworkA to allow for direct communication between networks. RIP was also updated
on each router providing information about the neighboring networks and serial connections.
NAT, or Network Address Translation, is used to turn multiple private IP addresses into one
when accessing public networks, such as the internet. This helps to reserve public IP addresses
and is useful because there is only a limited supply of addresses available for use. This is
especially true for IPv4 addresses, which are the current standard. However, as the mass adoption
of IPv6 addresses is inevitable, NAT may not be as prominently used in the future
Sincerely,
