Q

What is a Virtual IP Address (VIP/VIPA)?

A

An IP address that does not correlate to an actual physical network interface.

17
Q

What are Subinterfaces?

A

A virtual interface that is created by dividing up one physical interface into multiple logical interfaces

18
Q

What is a Unicast?

A

Data travels from a single source device to a single destination device

19
Q

What is a Multicast?

A

Data travels from a single source device to multiple (but specific) destination devices

20
Q

What is a Broadcast?

A

Data travels from a single source device to all devices on a destination network

21
Q

What is a Static Assignment?

A

Manually typing in the IP address for the host, its subnet mask, default gateway, and DNS server.

22
Q

What is a Dynamic Assignment?

A

Dynamic allocation of IP addresses

23
Q

What is the Subnet Mask of Class C addresses?

A

/24 (255.255.255.0)

24
Q

What is Classless Interdomain Routing (CIDR)?

A

Shorthand notation used to summarize continuous networks

Also called Route Aggregation

25
Q

What is the Internet Protocol Version 6 (IPv6) Addressing?

A

Written in hexadecimal notation (2018::4815:54ae). Each hexadecimal digit is 4 bits. (128 bits in address)

26
Q

What are some benefits of IPv6?

A

No broadcasts and no fragmentation

27
Q

What is Dual Stack?

A

IPv4 addresses run simultaneously with IPv6 addresses.

28
Q

What is Tunneling?

A

IPv6 traffic can carry over an existing IPv4 router

29
Q

What are the 3 types of IPv6 Addresses?

A

Unicast, Multicast, Anycast

30
Q

What is a Unicast Address?

A

Used to identify a single interface. Begins with 2000 to 3999

31
Q

What is a Multicast Address?

A

Used to identify a group of interfaces so that a packet can be sent to a multicast address and then be delivered to all of the interfaces in the group. Begins with FF.

32
Q

What is an Anycast Address?

A

Used to identify a set of interfaces so that a packet can be sent to any member of a set.

33
Q

What is a Link-Local Address?

A

Uses a stateless address autoconfiguration, or SLAAC. Begins with FE80.

34
Q

What is the Stateless Address Autoconfiguration (SLAAC)?

A

Discovers the current network that an interface is located on and then select its own host ID based on its MAC address using the EUI64 process.

35
Q

What is the Extended Unique Identifier (EUI)?

A

Allows a host to assign a unique 64-bit IPv6 interface identifier

36
Q

What is a Router Advertisement?

A

A router advertises their presence periodically and in response to solicitation
