An online store uses 6-bit binary sequences to identify each unique item for sale. The store plans to increase the number of items it sells and is considering using 7-bit sequences. Which of the following best describes the result of using 7-bit sequences instead of 6-bit sequences?

IP addresses are a way to identify devices connected to the internet (we'll learn more about what IP addresses are soon!). An IPv4 address is encoded in 32 bits or 4 bytes. Typically when you see an IP address it is organized as 4 separate numbers separated by periods, where each of the 4 numbers is stored in 1 byte (8 bits). With this in mind, which of the following would not be a possible IP address?

• 8.8.8.8

• 192.168.1.1

• 32.344.216.42

• 142.237.56.117
