[Day 11] 9. Site-Local and Link-Local Addresses in IPv6

1. Site-Local Addresses (FECO::/10):

Definition: Site-local addresses are used within a single site or organization and are not routable on the global Internet. They are intended for local communications.
Range: Addresses that start with the prefix
```
FEC0::/10
```
.
Example:
```
FEC0:1234:5678:9ABC::1
```
This address can be used for communication between devices within the same site but cannot be accessed from outside.

2. Link-Local Addresses (FE80::/10):

Definition: Link-local addresses are used for communication between nodes on the same local link (network segment). They are automatically configured and do not require a router.
Range: Addresses that start with the prefix
```
FE80::/10
```
, typically followed by zeros to complete the 128-bit address.
Example:
```
FE80::1A2B:3C4D:5E6F
```
This address is used for local communication within a network segment and is not routable beyond that segment.

Site-local addresses are for communications within an organization and are not globally routable (e.g.,
```
FEC0:1234:5678:9ABC::1
```
).
Link-local addresses are for communication between devices on the same local link and are automatically configured (e.g.,
```
FE80::1A2B:3C4D:5E6F
```
).
