Question

Difficulty: MediumIPv6 Addressing and Deployment

Match each IPv6 address or prefix to its corresponding deployment scope and functional classification.

  • 2001:db8:3c4d:15::/64Publicly routable address used for global internet connectivity
  • fe80::1a2b:3c4d:5e6fNon-routable link address required for local segment communication
  • fd12:3456:789a:1::1Internally routable address designated for private site communication
  • ff02::1:ff00:1234Multicast address utilized for IPv6 Neighbor Discovery address resolution

Answer

2001:db8:3c4d:15::/64 matches Publicly routable address used for global internet connectivity; fe80::1a2b:3c4d:5e6f matches Non-routable link address required for local segment communication; fd12:3456:789a:1::1 matches Internally routable address designated for private site communication; ff02::1:ff00:1234 matches Multicast address utilized for IPv6 Neighbor Discovery address resolution.
Each specified IPv6 address or prefix corresponds to a distinct deployment classification: 2001:db8:: represents Global Unicast, fe80:: represents Link-Local, fd12:: represents Unique Local, and ff02::1:ff00:: represents Solicited-Node Multicast.

Step-by-Step Solution

1
Examine the prefix range of 2001:db8:3c4d:15::/64.
Identified as a Global Unicast Address (GUA).
The 2000::/3 prefix range is designated for publicly routable global unicast communication.
2
Examine the prefix range of fe80::1a2b:3c4d:5e6f.
Identified as a Link-Local address.
The fe80::/10 block specifies non-routable link-local traffic restricted to a single network segment.
3
Examine the prefix range of fd12:3456:789a:1::1.
Identified as a Unique Local Address (ULA).
The fc00::/7 (fd00::/8) range provides private enterprise routing capabilities similar to IPv4 RFC 1918 addresses.
4
Examine the prefix range of ff02::1:ff00:1234.
Identified as a Solicited-Node Multicast address.
The ff02::1:ff00:0/104 range is generated from the last 24 bits of a node's IPv6 address for NDP address resolution.
