IPv6 Unicast Types
IPv6 includes several types of unicast addresses, each serving a different networking purpose.
Global Unicast Address
These addresses are routable on the Internet and begin with a global routing prefix, such as 2001::/3.
Example:
2001:0:3238:DFE1:63::FEFB
Unique Local Address (ULA)
These are similar to private IPv4 addresses and are used for private networks.
Example:
FDC8:BF8B:E62C:ABCD:1111:2222:3333:4444
Link-Local Address
These addresses begin with FE80::/10. They are limited to a single link and are not routable beyond that network segment.
Summary
- Global Unicast: public, Internet-routable
- Unique Local: private network use
- Link-Local: local segment only
