What is the primary purpose of using Network Address Translation (NAT) as described in the lecture slides?

• To increase the speed of the network

• To allow multiple devices on a private network to use the same public IP address

• To enhance the security of the network by encrypting data

• To assign unique IP addresses to each device on the internet

According to the lecture slides, what is a characteristic of private IP addresses?

• They can be directly connected to the internet

• They require permission from an ISP to be assigned

• They are not unique across different networks

• They are only assigned by DHCP servers

What is the primary benefit of using a NAT as mentioned in the text?

• It allows multiple devices to share a single public IP address.
