37
IPv4 currently supports a maximum of approximately how many unique (4,294,967,296) IP addresses?
4.3 billion
38
How many parts are there in a 128-bit IPv6 number?
6
39
Because of their potential to carry malware, these packets are often blocked by corporate firewalls

Global Unicast Address Indicator
44
A main advantage of IPv6 is?
Increased address space
45
These networks are easier to create and maintain, and services such as VoIP and Quality of Service (QoS) becomes more robust.
Peer-to-peer networks
46
How many octets does the IPv4 have?

Understanding IPv6 subnetting can be difficult on its own, let alone trying to remember/memorize your IPv6 address.
Readability
58
An advantage of IPv6 over IPv4 is that IPv6 supports multicast rather than broadcast.

59
An advantage of IPv6 over IPv4 is that IPv6 reduces the size of routing tables and makes routing more efficient and hierarchical.
More Efficient Routing
60
A ___________ will send the prefix of the local link in its router advertisements.
Router
61
Another advantage is that address auto-configuration (address assignment) is built into IPv6.
Simplified Network Configuration
62
Another disadvantage where IPv4 and IPv6 machines cannot communicate directly to each other, in the very rare circumstance that they would need to.

64
IPv6 is a standard developed by the?
Internet Engineering Task Force (IETF)
65
An organization that develops Internet technologies, anticipating the need for more IP addresses, created IPv6 to accommodate the growing number of users and devices accessing the Internet.
Internet Engineering Task Force (IETF)
66
What is the fourth part of the 128-bit IPv6 number?
Customer
67
It is the Internet's next- generation protocol, designed to replace the current Internet Protocol, IP Version 4.
IPv6 or Internet Protocol version 6
68
ACRONYM: EUI-64TM
64-bit Extended Unique Identifier
69
Recent estimates indicate that IPv4 addresses could be exhausted as soon as?
2012
70
It allows bandwidth-intensive packet flows (like multimedia streams) to be sent to multiple destinations simultaneously, saving network bandwidth.
Multicast
71
What is the size of bits of the IPv6?
128 bits
72
With it, your computers, routers, switches, and other devices run both protocols, but IPv6 will be the preferred protocol.
Dual-IP stacks
73
Another advantage is that by eliminating Network Address Translation (NAT), true end-to-end connectivity at the IP layer is restored, enabling new and valuable services.
