You are required to configure and test a DNS server. Configure a DNS server with both forward and reverse lookup.
You should configure a domain name zone of .itc333.edu, and a reverse name mapping zone of 192.168.15.0/24.
Configure A and PTR records for: host1 - 192.168.15.10, host2 - 192.168.15.11 and host3 - 192.168.15.12.
Configure a CNAME of www for host1, and a CNAME of dc1 for host2. Test the operation of your DNS server using an external client running DNS queries
