Unlike IPv4, IPv6 is designed to have multiple addresses.

<link> is a link-local IPv6 address. Think of this like 169.254.0.0/16, 
the "things arn't working" link-only IPv4 addresses you get when DHCP 
isn't working, or your router is offline. Except it's actually usable to 
talk to local network devices, like routers, NAS, etc.

<global> is your actual routable IPv6 address. This is the address used 
when talking to devices on other networks, and is actually routable back 
to you.
