IPv4 addresses are 128 bits in length.
*IPv6 addresses are represented by hexadecimal numbers.*
IPv6 addresses are 32 bits in length.

> What two statements describe characteristics of Layer 3
broadcasts? (Choose two).
Broadcasts are a threat and users must avoid using protocols that implement them.

Some IPv6 protocols use broadcasts.
