Wireshark D4 V5 - IPv6 Deep Dive

The video tutorial explains the advantages of IPv6 over IPv4, highlighting its larger address space, hexadecimal notation, and multicast capabilities. It delves into the structure of IPv6 headers, noting the absence of certain fields present in IPv4 headers, such as header length and checksum. The tutorial also covers the use of Wireshark to analyze IPv6 headers, detailing fields like version, traffic class, and flow label. The importance of understanding IPv6 for modern networks is emphasized, along with a brief mention of extension headers for security purposes.

What is one of the key differences between IPv6 and IPv4 in terms of address space?

• Both IPv6 and IPv4 use 32-bit addresses.

• Both IPv6 and IPv4 use 128-bit addresses.

• IPv6 uses 128-bit addresses, while IPv4 uses 32-bit addresses.

• IPv6 uses 32-bit addresses, while IPv4 uses 128-bit addresses.

Which protocol does IPv6 use instead of broadcast?

• Broadcast

• Unicast

• Anycast

• Multicast

What is a significant simplification in the IPv6 header compared to IPv4?

• IPv6 headers are more complex than IPv4 headers.

• IPv6 headers do not have a header length field.

• IPv6 headers have fields related to fragmentation.

• IPv6 headers include a header checksum.

What does the 'traffic class' field in an IPv6 header indicate?

• The total size of the payload

• The maximum number of nodes the packet can travel

• The version of the IP protocol

• The priority of the IPv6 traffic

What is the purpose of the 'flow label' field in an IPv6 header?

• To indicate the version of the IP protocol

• To label packets belonging to the same flow for special handling

• To specify the next header type

• To determine the payload length
