You are an administrator for the local DNS server for your company, and you have been tasked with manually adding the IPv6 reverse-mapping zones for your company’s domain to the server’s config file. The IPv4 domain name for your company’s Web site is abcxyz, and the IPv6 domain name is abcxyz-v6. You must know the IPv4 and IPv6 addresses for your company’s domain and any subdomains, such as marketing. abcxyz and marketing. abcxyz-v6 or sales. abcxyz and sales. abcxyz-v6, so you can configure the corresponding A and records as well as the ip6.arpa reverse-mapping zone names for each IPv6 address. Determine where you would find this data, and then, once you have gathered that information, construct the beginning of an IPv6 reverse-mapping zone based on that information. Use the $ORIGIN control statement and the following format: $ORIGIN ip6.arpa name PTR record
