D.1.4.3 Aggregatable Global Unicast Addresses
The global unicast addresses are globally unique IPv6 addresses. This address format is very well
defined in the RFC 2374 (An IPv6 Aggregatable Global Unicast Address Format). The format is:
Table 21
64 bits16248133
Interface IDSLA IDNLA IDRESTLA IDFP
where
FP = Format prefix. Value of this is “001” for Aggregatable Global unicast addresses.
TLA ID = Top-level Aggregation Identifier.
RES = Reserved for future use.
NLA ID = Next-Level Aggregation Identifier.
SLA ID = Site-Level Aggregation Identifier.
Interface ID = Interface Identifier.
D.1.4.4 Link-Local Addresses
Link-local addresses have the following format:
Table 22
64 bits54 bits10 bits
interface ID01111111010
Link-local address are supposed to be used for addressing nodes on a single link. Packets originating
from or destined to a link-local address will not be forwarded by a router.
D.1.4.5 Site-Local Addresses
Site-local addresses have the following format:
Table 23
64 bits16 bits38 bits10 bits
interface IDsubnet ID01111111011
Link-local address are supposed to be used within a site. Routers will not forward any packet with
site-local source or destination address outside the site.
D.1.4.6 Multicast Addresses
A multicast address is an identifier for a group of nodes. Multicast addresses have the following
