Basics
Address are split into:
- Unicast
- Global - similar to IPv4 public IP addresses. They have a prefix of 2000::/3
- Unique local - similar to IPv4 private addresses. There addresses have a prefix of FD00::/8 or FC00::/7
- Link local - there addresses are used for sending packet over the local subnet. There addresses have a prefix of FE80::/10.
- Anycast
- Multicast - prefix with ff00::/8
Packets sent to ::1 are sent to localhost
Packets sent to ::0 are sent on all interfaces.
Designated multicast address (just a few for example):
| All nodes |
ff02::1 |
| All routers |
ff02::2 |
| OSPF routers |
ff02::5 |
| EIGRP routers |
ff02::a |
