Exam: The Internet Protocol Flashcards
IPV4
The IPv4 address is a logical network address that identifies a particular host. Must be configured within a LAN for local and configured for remote communication (the internet).
Where can the IPV4 be found?
On the network interface card (NIC). Some servers can have more than one NIC and each of these has its own IPv4 address.
How do you know the local network IP address?
First three parts to the IP address
How do you know the individual host numbers?
Last part of the IP address
What is the purpose of the subnet mask in conjunction with an IP address?
to determine the subnet to which the host belongs
How many octets exist in an IPv4 address?
4
What criterion must be followed in the design of an IPv4 addressing scheme for end devices?
Each IP address must be unique within the local network
Which two parts are components of an IPv4 address?
network portion & host portion
What are two features of IPv4 addresses?
An IPv4 addressing scheme is hierarchical & IPv4 is a logical addressing scheme
How large are IPv4 addresses?
32-bit
Why do Multicast transmission reduce traffic?
Multicast transmission reduces traffic by allowing a host to send a single packet to a selected set of hosts that subscribe to a multicast group
What happens when a router receves a broadcast?
Routers do not propagate broadcasts. Each router interface connects to a broadcast domain and broadcasts are only propagated within that specific broadcast domain.
Which statement describes one purpose of the subnet mask setting for a host?
It is used to determine to which network the host is connected.
What is one reason for subnetting an IP network?
to reduce the scope of broadcast flooding
A user is unable to access the company server from a computer. On issuing the ipconfig command, the user finds that the IP address of the computer is displayed as 169.254.0.2. What type of address is this?
link-local
A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why?
This is a private IP address.
A host is transmitting a broadcast. Which host or hosts will receive it?
all hosts in the same network
Which address prefix range is reserved for IPv4 multicast?
224.0.0.0 – 239.255.255.255
What is the role of IANA?
managing the allocation of IP addresses and domain names
IPv6
IPv6 has a larger 128-bit address space, providing 340 undecillion (i.e., 340 followed by 36 zeroes) possible addresses.
What are the three categories for administrators migrating to IPv6 from the IETF?
Dual Stack, Tunneling, and Translation
Dual Stack
Dual stack allows IPv4 and IPv6 to coexist on the same network segment. (Known as native IPv6)
Tunneling
Transporting an IPv6 packet over an IPv4 network.
Transaltion
Network Address Translation 64 (NAT64) allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4. An IPv6 packet is translated to an IPv4 packet and an IPv4 packet is translated to an IPv6 packet.
