Module 10 - IPv6 Formats and rules Flashcards
(16 cards)
Which IP protocol was developed by the IETF as a successor to IPv4 to solve address depletion and enable future internet growth?
IPv6
Which protocol in IPv6 combines address resolution and autoconfiguration, unlike its IPv4 counterpart?
ICMPv6
Which mechanism slowed IPv4 depletion but introduces latency, breaks peer-to-peer communication, and complicates applications?
NAT (Network Address Translation)
Which class of internet-connected devices includes biomedical equipment, home appliances, and vehicles, increasing IP address demand?
IoT (Internet of Things)
Which IPv6 migration method encapsulates IPv6 packets within IPv4 packets for transport across IPv4 networks?
Tunneling
Which migration technique allows communication between IPv6-only and IPv4-only devices through protocol translation?
NAT64
Which technique enables devices to run both IPv4 and IPv6 protocol stacks simultaneously on the same network?
Dual Stack
Which transition technique should be avoided as a long-term solution but may be used where native IPv6 isn’t yet feasible?
Tunneling and Translation
Which numbering system is used to represent IPv6 addresses, using digits 0–9 and letters A–F?
Hexadecimal (base-16)
How many addresses can IPv6 support?
340 undecillion (36 zeros)
How many bits is a IPv6 address compared to a IPv4?
128-bits compared to 32- bits
Which rule allows you to shorten IPv6 addresses by eliminating leading zeros in a hextet?
Omitting leading zeros
Which term refers to a 16-bit segment of an IPv6 address, represented by four hexadecimal digits?
A hextet
Which property allows IPv6 addresses to be written in either lowercase or uppercase?
Case insensitivity
Which rule allows the compression of one or more contiguous 16-bit zero segments into a double colon?
replacing all zero Hextets with double colons
Which restriction applies to the use of a double colon in an IPv6 address?
It can only appear once per address
