    Hello Michiel.

    But I have never seen this actually used by an ISP to issue IPv6.

    I asked them what the v6 Prefix and the v6 Gateway address(s) were.
    They had little if any knowledge what my v6 IP's were let alone what
    the prefix or gateway would be.

    Odd. An ISP should know what address (blocks) they issue...

    Yes. The support staff seemed to know what a v6 IP was but didn't appear to know
    much about them. I would get the "Sorry, I don't have that information available". And they would then transfer me to someone who would end up giving me the same response.

    Linux needs to know those settings before one can save the network
    settings for that that Linux PC.

    I am not familiair with Linux, but I would be surprised if it differs, in that
    contrary to Windows, it requires user intervention to ceate a working IPv6 setup.

    Here in Linux for a manual/static v4 IP setup one has to provide the v4 IP, the subnet mask, and the gateway address. Similarly for v6 manual/static IP setup on has to specify the v6 IP, the prefix, and the v6 gateway address. All three have to be specified to be able to save the v4 or v6 IP network settings.

    Here I do not have to do anything to assign IPv6 addresses to my PC's. The router is assigned a /56 from the ISP. The router assigns a /64 to the local
    LAN en from that /64 IPv6 addresses are assigned to devices on the LAN. Either
    bij SLAAC or DHCP6.

    Here, the router is setup to accept and support a static IP block. And will accept traffic for any of the static IP's in that block. Each PC is assigned a static IP and accepts traffic for that particular static IP. The router doesn't assign an IP to the PC unless DHCP is in use. Here DHCP is in use but only for assigning local non-routeable IP's. .
    It is only when running servers that I have to intervene. I have to punch a hole in the firewall for the ports concerned and I have to update the DNS..

    Yes similarly here I have to make the necessary ports available.

    I have written a bash script that goes out and gets my v6 IP and IF it
    has changed it then updates the settings at my DNS provider for that
    domain. Which shouldn't be needed IF the v6 IP was actually static
    like they say that it is.

    So obviously you do not have static IPv6 addresses. :(

    Yes... Sadly that would be my conclusion also. They state that "A static v6 IP isn't necessary since each v6 IP is derived from a staticv4 IP". The question I then asked was why does the IP change? Again... I got the "Sorry, I don't have that information".

    Can you change ISPs in you area?

    Sadly, that isn't an option as Centurylink (Qwest) is the only fiber based ISP in the area and the only other options are cable or satellite. Neither of which (Last time I checked) provided static IP's.

    That does not give much confidence that they have people with the required knowledge... :(

    Here in Linux for a manual/static v4 IP setup one has to provide the
    v4 IP, the subnet mask, and the gateway address. Similarly for v6 manual/static IP setup on has to specify the v6 IP, the prefix, and
    the v6 gateway address. All three have to be specified to be able to
    save the v4 or v6 IP network settings.

    But why the need for manual configuration? The IPv6 protocol was designed to NOT need such things. Not for dynamic and not for static addresses. The CPE (the router at your home) negotiates an IPv6 prefix with the ISP via prefix delegation. The router advertises the prefix on the LAN and interfaces on the LAN are assigned addresses by SLAAC or DHCP6 using that prefix. No need fo user intervention.

    Here, the router is setup to accept and support a static IP block. And will accept traffic for any of the static IP's in that block. Each PC
    is assigned a static IP and accepts traffic for that particular static
    IP. The router doesn't assign an IP to the PC unless DHCP is in use.
    Here DHCP is in use but only for assigning local non-routeable IP's.

    It seems to me that your ISP runs some stripped version of IPv6... :(

    Yes similarly here I have to make the necessary ports available.

    But only for running servers. Configuring clients should be automatic without the need for user intervention.

    based ISP in the area and the only other options are cable or

    So you are stuck wih them. :(


    Cheers, Michiel
