Exploring IPv6 Concepts

What is the primary purpose of IPv6?

• The primary purpose of IPv6 is to provide a larger address space than IPv4.

• To enhance security features of IPv4

• To improve the speed of internet connections

• To reduce the size of data packets

How many bits are in an IPv6 address?

• 32 bits

• 64 bits

• 128 bits

• 256 bits

What are the main differences between IPv4 and IPv6?

• IPv4 uses 128-bit addresses and has unlimited address space; IPv6 uses 32-bit addresses.

• IPv4 and IPv6 both use 64-bit addresses and have the same address space.

• IPv4 is faster than IPv6 due to its simpler address structure.

• IPv4 has 32-bit addresses and limited address space; IPv6 has 128-bit addresses and virtually unlimited address space.

What is the format of an IPv6 address?

• Four groups of eight binary digits separated by dots

• Eight groups of three decimal digits separated by commas

• Six groups of five hexadecimal digits separated by semicolons

• An IPv6 address is formatted as eight groups of four hexadecimal digits, separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

What is the significance of the '::' notation in IPv6?

• The '::' notation signifies a compression of consecutive zero blocks in an IPv6 address.

• The '::' notation represents a specific type of IPv6 routing.

• The '::' notation is used to separate different IPv4 addresses.

• The '::' notation indicates the start of an IPv6 address.

What mechanisms does IPv6 use to facilitate address configuration?

• IPv6 requires manual configuration for all addresses.

• IPv6 exclusively uses static IP assignment for address configuration.

• IPv6 utilizes both Stateless Address Autoconfiguration (SLAAC) and DHCPv6 for address configuration.

• IPv6 does not allow any form of automatic address configuration.

What are the key fields in the IPv6 header?

• Checksum

• Fragment Offset

• Version, Traffic Class, Flow Label, Payload Length, Next Header, Hop Limit, Source Address, Destination Address

• Protocol Type

How does IPv6 multicasting differ from IPv4 multicasting?

• IPv6 multicasting has a smaller address space than IPv4.

• IPv6 multicasting uses the same address range as IPv4.

• IPv4 multicasting supports multicast listener discovery.

• IPv6 multicasting allows for a larger address space, uses a specific address range (FF00::/8), and supports advanced features like multicast listener discovery, unlike IPv4 multicasting.

What is the role of the Next Header field in the IPv6 header?

• The Next Header field is used for error checking in the packet.

• The Next Header field specifies the protocol of the next header in the packet.

• The Next Header field indicates the source address of the packet.

• The Next Header field defines the maximum transmission unit size.

What is IPv6 tunneling and why is it used?

• IPv6 tunneling allows IPv4 devices to communicate directly with each other.

• IPv6 tunneling is a method for encrypting IPv4 traffic.

• IPv6 tunneling is used to improve the speed of IPv4 connections.

• IPv6 tunneling is used to enable IPv6 communication over IPv4 networks.
