A Linux user is setting up a home server and needs to confirm their IPv6 address for proper configuration.
What command should the IT support technician recommend they use?
A . sudo dhclient -6
B . hostname -I
C . ip -6 addr
D . netstat -rn
Answer: C
Explanation:
ip -6 addr The ip -6 addr command is specifically designed to display IPv6 addresses associated with all network interfaces. It provides a clear and concise listing, making it ideal for users needing to verify or configure network settings related to IPv6.
Option A is incorrect because sudo dhclient -6 is used to obtain or renew an IPv6 address from a DHCP server, not to display existing configurations.
Option B is incorrect because hostname -I shows all network addresses (both IPv4 and IPv6) without distinguishing between them, which can be confusing.
Option D is incorrect because netstat -rn displays routing tables, which focus more on routes than on displaying specific interface addresses.
