Workaround: Believe you need to ensure that the IP address is for Server B (192.168.62.11) and not the IP address of Server C

Description:  It would appear that the IP address in the text is wrong as 192.168.62.12 is the IP address for SERVERC.

The primary name server on servera must only respond to queries and zone transfer requests from 127.0.0.1, ::1, 192.168.62.12, and fc62:5265:6448:6174::b. Its zone files are on workstation in /home/student/cr-network/files/zones. The zone files are incomplete, and must be edited to ensure that forward and reverse lookups work, based on the following table:

If I understand the lab correctly, ServerB is a caching DNS server and ServerA is the Primary DNS server.

Therefore, I believe that the IP address should be 192.168.62.11 so that it is ServerB's IP address.

Additionally, for the allow-query in the solutions section, we are only allowing IPv4 queries for the Primary DNS (BIND) but we are having ACLs and access specified for both IPv4 and IPv6 for Caching DNS (unbound) for Server B.
