IP ADDRESSES

Question 1

What is an IP address?

Answer 1

An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

Question 2

What are the two versions of IP addresses?

Answer 2

Back: The two versions of IP addresses are IPv4 and IPv6.

Question 3

What is the difference between IPv4 and IPv6?

Answer 3

IPv4 addresses are 32-bit addresses represented in dotted-decimal notation, while IPv6 addresses are 128-bit addresses represented in colon-separated hexadecimal notation.

Question 4

What is the range of IP addresses in IPv4?

Answer 4

The range of IP addresses in IPv4 is 0.0.0.0 to 255.255.255.255

Question 5

What is the range of IP addresses in IPv6?

Answer 5

The range of IP addresses in IPv6 is 0:0:0:0:0:0:0:0 to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF

Question 6

What are the different types of IPv4 addresses?

Answer 6

There are three types of IPv4 addresses: Unicast, Multicast, and Broadcast

Question 7

What is a Unicast IP address?

Answer 7

A Unicast IP address is a unique address assigned to a single host or device on a network. It is used for one-to-one communication between a sender and a receiver.

Question 8

What is a Multicast IP address?

Answer 8

A Multicast IP address is an address assigned to a group of devices. It is used for one-to-many communication where a sender sends a single packet to multiple receivers simultaneously.

Question 9

What is a Broadcast IP address?

Answer 9

A Broadcast IP address is an address used to send a packet to all devices on a network. It is used for one-to-all communication.

Question 10

What is a Public IP address?

Answer 10

A Public IP address is an IP address that is publicly routable on the internet, and is assigned to a device or network by an Internet Service Provider (ISP).

Question 11

What is a Private IP address?

Answer 11

A Private IP address is an IP address that is assigned for use within a private network and is not reachable from the internet.

Question 12

What is a Class A IP address?

Answer 12

A Class A IP address is an IPv4 address that uses the first octet to identify the network and the remaining three octets to identify the host.

Question 13

What is a Class B IP address?

Answer 13

A Class B IP address is an IPv4 address that uses the first two octets to identify the network and the remaining two octets to identify the host.

Question 14

What is a Class C IP address?

Answer 14

A Class C IP address is an IPv4 address that uses the first three octets to identify the network and the remaining octet to identify the host.

Question 15

What is a Subnet Mask?

Answer 15

A Subnet Mask is a mask used to divide a larger IP address space into smaller subnets, allowing for more efficient use of IP addresses.

Question 16

What is a CIDR notation?

Answer 16

CIDR notation is a compact representation of an IP address and its associated routing prefix. It is used to specify the number of bits used for the network portion of an IP address.

Question 17

What is DHCP?

Answer 17

DHCP (Dynamic Host Configuration Protocol) is a protocol used to automatically assign IP addresses to devices on a network.

Question 18

What is ARP?

Answer 18

ARP (Address Resolution Protocol) is a protocol used to map a network address (such as an IP address) to a physical address (such as a MAC address) on a local network.

Question 19

What is NAT?

Answer 19

NAT (Network Address Translation) is a method of remapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

Question 20

What is a Default Gateway?

Answer 20

A Default Gateway is the IP address of a router on a local network that is used to forward packets to other networks when the destination IP address is not on the local network.

Question 21

What is a reserved IP address range?

Answer 21

A reserved IP address range is a set of IP addresses that have been set aside by IANA (Internet Assigned Numbers Authority) for specific purposes and cannot be assigned to hosts or networks.

Question 22

What is a loopback IP address?

Answer 22

A loopback IP address is an IP address assigned to the loopback interface of a device, it is used for internal testing and communication within the device. The common IP for this is 127.0.0.1

Question 23

What is an IP address conflict?

Answer 23

An IP address conflict occurs when two or more devices on the same network have been assigned the same IP address. This can cause communication issues and network connectivity problems.

Question 24

What is a static IP address?

Answer 24

A static IP address is an IP address that is manually assigned to a device, rather than being assigned dynamically through DHCP.

Question 25

What is a dynamic IP address?

Answer 25

A dynamic IP address is an IP address that is assigned to a device dynamically, rather than being assigned manually. The DHCP server assigns the address to the device.

Question 26

What is a public IP address?

Answer 26

A public IP address is an IP address that is publicly reachable on the Internet and is assigned to a device or network by an Internet Service Provider (ISP).

Question 27

What is a private IP address?

Answer 27

A private IP address is an IP address that is assigned for use within a private network and is not reachable from the Internet.

Question 28

What is a static NAT?

Answer 28

A static NAT (Network Address Translation) is a mapping of a private IP address to a public IP address. It allows a device in a private network to be reachable on the public Internet using a static, pre-defined mapping.

Question 29

What is a dynamic NAT?

Answer 29

A dynamic NAT is a mapping of a private IP address to a public IP address, but the mapping is done dynamically and may change over time. It allows multiple devices in a private network to share a pool of public IP addresses.

Question 30

What is an IPv4 address depletion?

Answer 30

IPv4 address depletion refers to the exhaustion of the pool of available IPv4 addresses that can be assigned to devices on the Internet. IPv4 addresses are 32-bits long and have a maximum of 4.3 billion addresses, and with the increasing number of devices connected to the internet, IPv4 address depletion is becoming a concern.
