Q

Explain the shortcut you may use in IPv6 address notation that involves the use of Colons?

A

IPv6 uses a colon as a separator between each group in the address.

Q

Briefly describe why DHCP is necessary for IPv6?

A

DHCP is still important in IPv6, but in slightly different ways than it was in IPv4.
