Dear inet6 guys, I don't know the kind of addresses FreeBSD uses for autoconfigured link-local addresses. For example: fe80::20e:cff:fe34:2bf8%em0 What the hack is %em0 ??? Interestingly I can use this address, but ping6 fe80::20e:cff:fe34:2bf8 doesn't work.... The Handbook doesn't clarify this mysterious address. Is it FreeBSD specific?
