(Select two.) 32-bit address 64-bit address Four decimal octets 128-bit address Eight hexadecimal quartets Explanation IP version 6 addresses are 128-bit addresses. They are commonly written using 32 hexadecimal numbers organized into eight quartets. Each quartet is represented as a hexadecimal number between 0 and FFFF. The quartets are separated by colons. IP version 4 addresses are 32-bit addresses. They have four octets. Each octet is an eight- digit binary number. Each octet has a decimal value between 0 and 255.

The last 64-bit portion is called the interface ID, or host portion of the address. The host portion of the address assigned to an interface must be unique.

The quartets are separated by colons. An IPv6 address is made up of 128 binary digits. IP version 4 addresses use decimal numbers organized into four octets and separated by periods.

(Select two.) A82:5B67:7700:AH0A:446A:779F:FFE3:0091 165.15.78.53.100.1 343F:1EEE:ACDD:2034:1FF3:5012 6384:1319:7700:7631:446A:5511:8940:2552 141:0:0:0:15:0:0:1 Explanation An IPv6 IP address is a 128-bit address listed as eight 16-bit hexadecimal sections. Leading zeros can be omitted in each section. Therefore, 6384:1319:7700:7631:446A:5511:8940:2552 and 141:0:0:0:15:0:0:1 are both valid IPv6 IP addresses. A single set of all-zero sections can be abbreviated with two colons (::). Therefore, 141::15:0:0:1 is a valid way of writing that address. Digits in a hexadecimal system range from 0-9 and A-F. H is not a valid hexadecimal number. 343F:1EEE:ACDD:2034:1FF3:5012 is too short, having only six sections instead of eight. 165.15.78.53.100.1 is too short, and the sections are separated by periods instead of colons.
