If you want NAT really hard, you can use it with IPv6 too. fd00::/8 exist. > Many things. Try to organize the primary and redundant connection to > the SP (that is needed for every business). A connection with 2 prefixes (or even 2 IPv4 addresses) via 2 ISPs is never redundant, unless you set it up this way with both ISPs cooperating. If you really want redundancy, you have to get your own ASN and route it via 2 independent ISPs. Or let 2 ISPs route your network ranges. In all other cases with NAT and 2 IPv4 addresses, connections will be lost when one of the connections fail, as the remote system won't accept the packages from a different address unless a new connection is being established. > The fact that every subnet is /64 is convenient.

Are you aware that EUI64 is only one way to generate the addresses and that the 64 bits can be randomly filled or be static? -- Gruß Marco Send unsolicited bulk mail to [email protected]
