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
server2.myuni.edu.au 192.168.1.11
pc2.myuni.edu.au 192.168.1.22
pc3.myuni.edu.au 192.168.1.23

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.)
