Q

What is a Unicast IP address?

A

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.

Q

What is a Multicast IP address?

A

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.

Q

What is a Broadcast IP address?

A

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.

Q

What is a Public IP address?

A

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).

Q

What is a Class A IP address?

A

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.

Q

What is a Subnet Mask?

A

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.

Q

What is a CIDR notation?

A

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.

17
Q

What is DHCP?

A

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

18
Q

What is ARP?

A

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.

19
Q

What is NAT?

A

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.

20
Q

What is a Default Gateway?

A

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.

21
Q

What is a reserved IP address range?

A

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.

22
Q

What is a loopback IP address?

A

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

23
Q

What is an IP address conflict?

A

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.

24
Q

What is a static IP address?

A

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

25
Q

What is a dynamic IP address?

A

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.

26
Q

What is a public IP address?

A

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).

27
Q

What is a private IP address?

A

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

28
Q

What is a static NAT?

A

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.

29
Q

What is a dynamic NAT?

A

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.

30
Q

What is an IPv4 address depletion?

A

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.
