Questions and Answers
What is the purpose of a subnet mask in an IP addressing scheme?
What is the purpose of a subnet mask in an IP addressing scheme?
- To distinguish logical network and host portions within the IP address (correct)
- To identify the physical location of the device on the network
- To encrypt the IP address for secure communication
- To allocate IP addresses to devices on the same network
In IPv6, what is the length of the address and where is the interface address portion located?
In IPv6, what is the length of the address and where is the interface address portion located?
- 64 bits long, always the first 64 bits
- 128 bits long, always the last 64 bits (correct)
- 32 bits long, varies based on the network prefix
- 256 bits long, always the first 128 bits

What is the function of a default gateway in an IP addressing scheme?
- To identify the physical location of the device on the network
- To assign IP addresses to devices on the same network
- To provide secure encryption for network communication
- To route traffic between the local network and external networks (correct)

Study Notes
Subnet Mask Purpose
- Defines the network and host portions of an IP address.
- Facilitates the segmentation of a network into smaller, more manageable subnetworks.
- Enhances security and improves overall network performance by isolating network segments.
IPv6 Address Length and Structure
- IPv6 addresses are 128 bits in length.
- The address is typically represented in eight groups of four hexadecimal digits.
- The interface address portion is located in the last 64 bits, also known as the Interface ID.
Default Gateway Function
- Acts as an access point or IP router that a networked device uses to send data to devices outside its local subnet.
- Essential for Internet access and communication with external networks.
- Facilitates routing traffic between local devices and outside networks.
Available Host Address in 192.168.1.0/24
- The first available host address in the 192.168.1.0/24 network is 192.168.1.1.
- The network address (192.168.1.0) cannot be assigned to hosts, and the last address (192.168.1.255) is reserved for broadcast.
