Careful. fec0: is site-local, not link-local, which is fe80:. I've never seen a zone ID attached to a site-local address; I thought the zone shit was introduced at the same time they deprected the site-local addresses... ipv6 is a shitshow. Cursory inspection of relevant RFCs does not lead to clarity. Godspeed. khm
