That's what FreeBSD does itself for INET6=20 enabled kernels. Now in the 24-16-24 scheme of th interface id part of the IPv6 address, the= =20 16 bits were inserted with the value FFFE. And bit 57 was changed to one!=20 Why???? What if it is alread one? Or isn't tehre any vendor who can have=20 bit 41 of his MAC 1? Now I want to use a dedicated interface, which is in a different subnet,=20 for 5 jails. How do I do that if I want to keep the MAC relation and if=20 I'm not allewd to change the FFFE insert? It isn't possible then, is it? What should I do instead? Invent my own 64-bit scheme? I hope you understand my questions, thanks a lot in advance, =2DHarr --nextPart14788579.96RIx7jExv Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBC/PApBylq0S4AzzwRAspoAJ9G/rHaQ7P/aQoNfXf2Mczx886PIQCfXgd/ 4kuK7IPeDMwa4IvMAhG1vxc= =A3zg -----END PGP SIGNATURE----- --nextPart14788579.96RIx7jExv--
