Dear inet6 guys, I don't know the kind of addresses FreeBSD uses for autoconfigured=20 link-local addresses. =46or example: fe80::20e:cff:fe34:2bf8%em0 What the hack is %em0 ??? Interestingly I can use this address, but ping6=20 fe80::20e:cff:fe34:2bf8 doesn't work.... The Handbook doesn't clarify this mysterious address. Is it FreeBSD=20 specific? Thanks in andvance, I posted this also to current@ since I got no answer=20 from questions@ =2DHarry > > Thanks, > > -Harry > > > So far I know how to generate s site-local address on basis of the MAC > > address of the interface.
