Task 1: DNS configuration
Create the DNS zone file for the new zone “myuni.edu.au’ and its reverse zone file. The new domain will occupy the IP ranges 192.168.1.0/24.
a. Setup the DNS on the host dns.myuni.edu.au.
b. In their SOA records, serial numbers must be prefixed with the current date and have a two-digit update number suffix: yyyymmddss, e.g. 2020090901
c. Add a single MX record for each zone with priority 50 which will direct to smtp.myuni.edu.au.
d. Add appropriate A records and PTR records for the following physical hosts: server1.myuni.edu.au 192.168.1.10
e. Add “www” CNAMEs to “server2”; “dns” to “server1”; and “smtp” to “server1”. (You can assume that the glue records will be handled by somebody else.)

Task 2: Network planning (you don’t need to implement this task in VM)
A university has a main campus and a remote campus at another location. The default router to the Internet on the main campus has an IP address of 10.0.0.1/24. The main campus network is connected to the Internet through a router called RouterA (Router A and the default router are two different routers). The main campus has no more than 15000 staff and students. The remote campus network is connected to the main campus network through a router called RouterB. The remote campus has no more than 200 staff
and students. All staff and students should be able to access to the Internet and to the resources on both campuses.
Your task is to plan the campus networks.
a) Propose appropriate subnet ranges for both campuses from the 16-bit prefix block of IPv4 private addresses (i.e., 192.168.0.0/16) *R. Answer the question with your calculation.
b) Draw a diagram to depict the networks with IP addresses notated with CIDR notation assigned to the all interfaces of bother routers for two campuses. Label the interfaces of routers on the diagram using eth0 or eth1.
c) Show the routing table of the RouterA that meets the requirements of both campuses. Show the columns of Destination, Gateway, Genmask, Flags and Iface in the routing table as shown by the Linux command route.
