IPv6

Ben is a Network Administrator at Business Software Solutions Ltd. The company uses a Windows-based operating system across its network. Ben discovers the following mail exchange record on the server:

max1.passguide.com. IN A 613.0.2.1  
  
IN AAAA 4ffe:d00:1:1::88 -

Which conclusion can Ben draw from this record?

  • A It indicates the configuration of the POP3 server (max1) on the site passguide.com on how to handle e-mails from the site 613.0.2.1 and an internal computer with NIC address 4ffe:d00:1:1::88.
  • B It indicates the preference of the record.
  • C It indicates the configuration of the SMTP server (max1) on the site passguide.com on how to handle e-mails from the site 613.0.2.1 and an internal computer with NIC address 4ffe:d00:1:1::88.
  • D It indicates part of the DNS configuration for the primary server to handle both IPV4 and IPV6 requests.
Explanation

An A record associates a hostname with an IPv4 address, while an AAAA record associates it with an IPv6 address. Together, they form DNS configuration that lets the host resolve for both IPv4 and IPv6 requests; they do not specify POP3/SMTP processing or record preference.
