fe80::/10

fe80

Last updated 2 Nov 2026 from the IANA IPv6 Special-Purpose Address Registry

Short answer

fe80::/10 is IPv6 link-local: every IPv6 interface has one, and it only works on the local network segment.

Block	fe80::/10
First – last	fe80:: – febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff
Size	a /10 (2^118 addresses)
Name in the registry	Link-Local Unicast
Defined in	RFC 4291
Allocated	2006-02
Valid as source / destination	True / True
Forwardable	False
Globally reachable	False

What it means

RFC 4291 gives every IPv6 interface an fe80:: address automatically. Devices use it to find the router and neighbours on the same link.

It is never routed beyond that link, so it says nothing about you to the wider internet.
