Zorluk: OrtaIPv6 Addressing and Prefixes

Match each IPv6 prefix or address block on the left with its correct architectural scope and function on the right.

  • 2000::/3Global Unicast Address range reserved for publicly routable Internet communication
  • fe80::/10Link-Local unicast prefix mandatory for single-segment neighbor communication
  • fc00::/7Unique Local Address prefix used for private internal site routing
  • ff02::2All-routers link-local multicast address targeting all routers on the segment

Cevap

2000::/3 matches Global Unicast Address range reserved for publicly routable Internet communication; fe80::/10 matches Link-Local unicast prefix mandatory for single-segment neighbor communication; fc00::/7 matches Unique Local Address prefix used for private internal site routing; ff02::2 matches All-routers link-local multicast address targeting all routers on the segment.
Each IPv6 address prefix maps precisely to its RFC-defined scope: 2000::/3 is Global Unicast, fe80::/10 is Link-Local, fc00::/7 is Unique Local, and ff02::2 is the all-routers multicast group address.

Adım Adım Çözüm

1
Identify the primary block for Global Unicast Addresses (GUA)
2000::/3 encompasses all addresses from 2000:: through 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff, which are globally routable.
IANA allocates GUA prefix blocks starting within the 2000::/3 range.
2
Identify the designated Link-Local unicast prefix scope
fe80::/10 defines the range fe80:: through febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff used for intra-link communication.
IPv6 devices use link-local addresses for neighbor discovery and router solicitations.
3
Identify the private/internal IPv6 address range
fc00::/7 covers the block fc00:: through fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff for Unique Local Addresses.
ULAs provide non-globally routable addressing within private organizational boundaries.
4
Identify specific well-known IPv6 multicast group addresses
ff02::2 is the link-local scope multicast address received by all active routers on a network segment.
Multicast prefix ff00::/8 uses the scope indicator 2 (link-local) and group ID 2 (all routers).
