Zorluk: OrtaIPv6 Addressing and Prefixes

Match each IPv6 address category on the left with its designated reserved prefix block on the right according to RFC standards.

  • Global Unicast2000::/3
  • Unique Localfc00::/7
  • Link-Localfe80::/10
  • Multicastff00::/8

Cevap

Global Unicast corresponds to 2000::/3, Unique Local corresponds to fc00::/7, Link-Local corresponds to fe80::/10, and Multicast corresponds to ff00::/8.
Each IPv6 category matches its standards-based prefix block: Global Unicast matches 2000::/3, Unique Local matches fc00::/7, Link-Local matches fe80::/10, and Multicast matches ff00::/8.

Adım Adım Çözüm

1
Identify the Global Unicast prefix allocation.
Global Unicast uses binary prefix 001, which maps to 2000::/32000::/3.
RFC 4291 reserves 2000::/32000::/3 for publicly routable global unicast addresses.
2
Identify the Unique Local address range.
Unique Local uses binary prefix 1111 110, which maps to fc00::/7fc00::/7.
RFC 4193 reserves fc00::/7fc00::/7 for private enterprise network addressing.
3
Identify the Link-Local address prefix.
Link-Local uses binary prefix 1111 1110 10, which maps to fe80::/10fe80::/10.
RFC 4291 defines fe80::/10fe80::/10 for communications confined to a local physical or virtual link.
4
Identify the Multicast address range.
Multicast uses binary prefix 1111 1111, which maps to ff00::/8ff00::/8.
RFC 4291 assigns all IPv6 addresses starting with FF to multicast functionality.
