A technician is configuring network parameters on a newly installed workstation. Upon reviewing the network interface details, the technician observes that the system has automatically assigned itself an IPv6 address of . The host can successfully communicate with neighboring systems connected to the same physical switch, but cannot reach devices on external subnets or the internet. Which of the following best explains why the workstation is unable to communicate beyond its local network segment?
- AThe workstation is using an APIPA address because the local IPv6 DHCP server was unreachable during startup.
- The host is configured with a link-local IPv6 address, which routers will not forward outside the local network segment.Answer
- CAn unmanaged switch is required to translate link-local IPv6 frames into routable Layer 3 packets.
- DThe workstation relies on a DNS server to dynamically convert the link-local IPv6 address into a routable lease.
Answer
The host has only been assigned a link-local IPv6 address (), which is restricted to the immediate network segment and cannot be forwarded by routers to external subnets.
IPv6 link-local addresses starting with the prefix are restricted to communication within a single physical or virtual link. Routers automatically drop traffic originating from or addressed to link-local addresses, preventing communication beyond the local segment until a routable address is configured.
