-----Original Message----- For outgoing, at least for a mailserver, it does matter a lot which address is being used. Using the random address would mean the receiving server would have no way of identifying the sending server. If using dhclient6 actually means not getting a random address assigned, that's probably what I need to do. -----Original Message----- I surely hope that you use something else then your ip for identifying... -) So you probably mean "the (sub-)net allowing connections" V6 offers some privacy by using random numbers instead of fixed mac-addresses. One of the nicest things about v6 is, that you can add a lot of multiple addresses to you NIC. So while still using a randomized address for surfing, you can still add additional fixed addresses for other purposes. afaicr, the idea was: "outgoing=random, incoming=fixed" for both servers and desktops hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
