Module 10: IPv6 Addressing Formats and Rules

Which two statements are correct about IPv4 and IPv6 addresses?

- IPv6 addresses are represented by hexadecimal numbers - IPv4 addresses are 32 bits in length

What are two methods that can be used to shorten the IPv6 address notation?

- use of a double colon (::) to represent a string of all zero hextets - omit all leading zeros from all hextets in the address

IPv6 increases the IP address size from 32 bits to how many bits?

128

Which IPv6 address notation is valid?

2001:DB8:0:1111::200
