Understanding IP Addresses and Networking

What is an IP address?

• It's a physical address for a network card.

• It's an identifier for a computer or device on a network.

• It's a type of network cable.

• It's a software program that manages network traffic.

What are the two different types of IPv4 addresses?

• Static and Dynamic

• Local and Global

• Public and Private

• Internal and External

Which statement is true about public IP addresses?

• They are unique globally.

• They are assigned by your router.

• They are not publicly registered on the internet.

• They are primarily used for internal networks.

Why were private IP addresses developed?

• To improve internet speed.

• To enhance network security directly.

• To allow direct communication between all devices globally.

• To prevent a shortage of public IPv4 addresses.

A device with a private IP address cannot:

• Directly access the internet.

• Be converted into a public IP address by a router to access the internet.

• Only communicate with other private IP addresses.

• Are assigned by the Internet Service Provider (ISP).

Which service in a router assigns private IP addresses to internal devices?

• DHCP

• NAT

• DNS

• ARP

What does NAT stand for in the context of IP addresses?

• Dynamic Host Configuration Protocol

• Domain Name System

• Network Address Translation

• Address Resolution Protocol

Which IP address range is typically used for Class C private IP addresses in small organizations or homes?

• 10.0.0.0 - 10.255.255.255

• 172.16.0.0 - 172.31.255.255

• 169.254.0.0 - 169.254.255.255

• 192.168.0.0 - 192.168.255.255

How can you find your public IP address?

• By typing 'ipconfig' in the command prompt.

• By checking the router's settings.

• By looking at the network adapter properties.

• By visiting a website like 'whatismyipaddress.com'.

Regarding security, which statement is true about public and private IP addresses?

• Private IPs are generally more secure because they are hidden from the internet.

• Public IPs are more secure because they are unique and registered.

• Both public and private IPs offer the same level of security.

• Security depends solely on the firewall, not the IP type.
