IPv6 has many new and different characteristics and functionality compared to IPv4. Which of the following is an incorrect functionality or characteristic of IPv6? i. IPv6 allows for nonscoped addresses, which enables an administrator to restrict specific addresses for specific servers or file and print sharing, for example. ii. IPv6 has IPSec integrated into the protocol stack, which provides application-based secure transmission and authentication, iii. IPv6 has more flexibility and routing capabilities compared to IPv4 and allows for Quality of Service (QoS) priority values to be assigned to timesensitive transmissions. iv. The protocol offers autoconfiguration, which makes administration much easier compared to IPv4, and it does not require network address translation (NAT) to extend its address space. i, iii i, ii ii, iii ii, iv
