Correct arrangement
- CNAME
- SOA
- NS
- AAAA
- PTR
Explanation
The correct arrangement maps each DNS record type to its specific function: CNAME (Canonical Name) creates an alias from one domain name to another; SOA (Start of Authority) contains administrative information about a DNS zone including the primary nameserver and zone serial number; NS (Name Server) identifies the authoritative nameservers for a domain; AAAA maps a hostname to a 128-bit IPv6 address (analogous to A records for IPv4); and PTR (Pointer) performs reverse DNS lookups, mapping an IP address back to a hostname. Each record type has a distinct and non-interchangeable role in the DNS system, and the AAAA record is specifically the IPv6 address record, making it critical to differentiate from A records used for IPv4.
