Port 567 is utilized by which protocol?

DNS
DHCPv6 (servers)
HTTP
FTP

The correct answer is: DHCPv6 (servers)

Port 567 is used by the DHCPv6 protocol, which stands for Dynamic Host Configuration Protocol for IPv6. This protocol is essential for the assignment of IP addresses and configuration settings to devices on an IPv6 network. Unlike its predecessor, DHCP for IPv4, which commonly uses ports such as 67 and 68, DHCPv6 operates on port 547 for clients and port 546 for servers. The purpose of DHCPv6 is to enable devices to automatically obtain network configuration, such as IP addresses, without manual intervention, streamlining network administration and improving connectivity for users. This facilitates a more efficient method of managing IP assignments in modern network environments, particularly as the adoption of IPv6 continues to grow. Understanding the specific ports associated with network protocols is crucial for network security practitioners as it aids in identifying legitimate traffic versus potentially malicious activity. For example, knowing that DHCPv6 uses port 547 allows security professionals to properly configure firewalls and monitoring tools based on expected traffic patterns in their networks.
