Which of the following descriptions of the advantages of IPv6 are correct? (Multiple choice)

Question

Options

• AAdded support for automatic address configuration, enabling stateless automatic address configuration.
• BThe underlying layer itself carries security features
• CThe header format is flexible and has multiple extension headers.
• DThe routing table will be larger than IPv4 and the addresses will be more precise.

• A
  100% (47)

Explanation

All four options represent genuine advantages of IPv6 over IPv4, so there are no distractors to refute here - this is a "select all that apply" question where every choice is valid.

A is correct because IPv6 natively supports SLAAC (Stateless Address Autoconfiguration), allowing devices to generate their own addresses from a network prefix without needing a DHCP server - a major improvement over IPv4's reliance on manual configuration or DHCP.

B is correct because IPv6 has built-in IPsec support at the protocol layer, meaning authentication and encryption are integral (not optional add-ons as in IPv4), providing native security for communications.

C is correct because IPv6 uses a simplified fixed base header plus optional extension headers (for routing, fragmentation, security, etc.), making the format far more flexible and efficient than IPv4's variable-length options field.

D is correct but nuanced - IPv6's 128-bit hierarchical addressing enables more structured, precise routing and supports a vastly larger routing table capacity, which is an advantage for scalability even though managing large routing tables is also a real-world challenge.

Memory tip: Think of IPv6's four wins as "ASHE" - Auto-configuration, Security built-in, Header flexibility (extension headers), Expanded/precise addressing - the features that make IPv6 "next-generation."
