    Hello All!

    It has been suggested that I use ipv6, in a nutshell are there advantages of using, disadvantages to not using? Or is it just fun and nerdy to do so?

    It is convenient and useful. There are already sites and even Fido nodes available only over IPv6. Well, for Crimea there is one more advantage - it allows avoiding restrictions. ;)

    Have a nice night.

    Well, it is fun and nerdy and if there is any of that Pioneer Spirit left you would jump in right away. ;-)

    But IPv6 isn't just nerdy and fun, it is the future. The Internet has run out of IPv4 addresses many years ago. Not in the sense that thet are burned, all the about 4000 millions of addesses that fit in a 32 bit number are still there, but there are no new ones. There are not enough IPv4 adresses to let everyone have one. And so providers revert to tricks like CGNAT (CArrier Grade Nat) to "solve" those problems. But the real solution is IPv6. IPv6 uses 128 bit adresses, so there is no longer a shortage of addresses. In fact with IPv6 you do not just get one address per household, you get a VERY LARGE block of addresses. Enough to let every appliance in your local network have its own globally routable unique IP address. No more need for non standard ports when running more than one server.

    As you can see in the list that I publish weekly in Fidonews, there presently are 107 nodes in Fidonet that support IPv6. The counter goes to 108, but one in the list is flagged as down. I will post the list in the next message. There are four nodes flagged as INO4. That means they no longer have a public IPv4 address for accepting incoming calls. To connect with these nodes you need IPv6. I had expected this number to be larger by now, but we sure can expect this number to grow when ISP's stop issuing public IPv4 addresses to customers.

    When your ISP already provides you with IPv6, making your Fidonet nodes IPv6 capable is very easy. I see that you run Binkd Linux. Linux has been supporting IPv6 for "ages" and binkd supports IPv6 from version 1.00. All you have to do is open port 24554, or 24556 in your case, in your firewall(s) and add an AAAA record to awesome.abon.us.

    So how about it?


    Cheers, Michiel

    It is simply a new version of IP.
    We are out of stock of IPv4 addresses, and there are plenty of IPv6 addresses.

    There are people that only have a public IPv6 address and a private carrier grade NAT IPv4.
    If you only have an IPv4 address, then you cannot communicate with them any more.

    So the advantage is that you can keep communicating with hosts that only have public IPv6 addresses.

    And as there are no longer very cheap/free IPv4 addresses available, the move to IPv6 will be much stronger in the future.

    For now you simply need IPv4 to address hosts with A records, and IPv6 with AAAA records. Normally servers will add both nowadays. (but for how long ...)

    ricsi@menedetter:~$ host menedetter.net
    menedetter.net has address 45.142.176.108
    menedetter.net has IPv6 address 2a03:4000:4a:c5f::1

    ricsi@menedetter:~$ host facebook.com
    facebook.com has address 157.240.17.35
    facebook.com has IPv6 address 2a03:2880:f15b:83:face:b00c:0:25de

    Plus you encode "messages" into your address like Facebook does above, or some fido nodes do:
    ricsi@menedetter:~$ host fido.ricsi.priv.at
    fido.ricsi.priv.at has address 45.142.176.108
    fido.ricsi.priv.at has IPv6 address 2a03:4000:4a:c5f:f1d0:2:310:31

    Your ISP is an odd one out. Most ISPs either just offer IPv6 or they just don't. That they do offer it but only after a specific request from the customer is an exception.

    and start reading on how to implement in my network.. I have unifi at
    home here...

    We wait patiently. ;-)

    Thank you... I have watched some videos and read some online journals and I am interested enough to pursue this. I do have just a basic question, will I have ipv4 and ipv6 concurrently? Or do I have to abandon ipv4 to utilize ipv6? That is the only thing I cant seem to find specifics on...

    Thank you

    IPv4 and IPv6 work concurrently quiet happily.
    If your ISP offers both, you will use them together normally.

    Some ISPs that have few IPv4 addresses left, will give you a 100.0.0.0/8 carrier grade NAT IP.
    You can use it to reach IPv4 services, but you cannot be contacted from other IPv4 hosts. (just like home NAT on 10.0.0.0/8 or 192.168.x.0/24. (just that it is done in the network of your ISP not on your router)

    You could get the answer with one single command:

    % ip addr list dev lo
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    ^^^^^^^^^^^^^^^^
    valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
    ^^^^^^^^^^^^^
    valid_lft forever preferred_lft forever

    Most ISPs still offer a so called "Full Dual Stack" connection. That means you will still be able to use IPv4 as you do now and use IPv6 in addition to that. The OS and the application will figure out for themselves what protocol to use. If the other side also supports IPv6, IPv6 will tried first by default.

    As Ricsi already mentioned some ISPs that are short of IPv4 addresses issue so called DS-Lite. But I do not think that will apply to you. European and Asian ISPs sometimes use DS-Lite, but in the US ISP's still have enough IPv4. I am not aware of US ISPs going DS-Lite yet.

    So for the moment assume that you will have Full Dual Stack en use both IPv4 and IPv6 for both incoming and outgoing connections.

    When it comes to routing priority, IPv6 takes priority over IPv4, so it'll appear to be faster if you're dual stacked.
