How do I use my /64 IPv6?

elgselgs Member
edited July 2015 in General

I got a /64 block of IPv6 addresses on my server, which is 2^64=18,446,744,073,709,551,616 addresses. I don't even know how to read it. I'm wondering what I can do with such a scary number of addresses? I literally need to be educated about the IPv6.

    SOP for IPv6 is assign one to your device to use and talk about how many you have left over on social media. :)

  • Is there a way to set my server to listen on all /64 addresses, but to use a random address as the outgoing ip?

    Will shill for carrots.

    @wwabbit If you like slow reboots and using a lot of RAM I'm sure you can.

    I usually just use an IPv6 for nginx as I do get some visitors that use it.

    Add this: 24/7 maxed out CPU core(s)

    [Linking that many IP addresses to one server would cause CPU, RAM, and SSD/HDD suicide (assuming that the network connection isn't saturated yet).]

    It is not possible. I mean you can do it, but will not work.

    why would you even want to?

    With a router you can forward the entire /64 to a single address.

  • Hurricane Electric has some learning resources for IPv6. Take a look here - https://ipv6.he.net/presentations.php

    +1 on the HE certification program (you even get a t-shirt ;) )

    Thanked by 1DianTama

    RIPE LIR: Contact me for ASN registrations/IPv6. No IPv4 space left.

  • Count them. Print them.

    That as well. Have the full /64 printed in a t-shirt. Badass!

    Assign one to every item in your house, to prepare for when they are internet of things compatible.

    EDIT: Tunnel a /56 to your house and use that!

    Assign one to your VPS but try and figure out cool words you can create using 0-9 and a-f

    Is there a way to run multiple VPNs using /64 IPv6 on a VPS?

    I like what she said, not what it means.

    I'm actually wondering technically why some people says subnet smaller than /64 is not really useful.

    1) You are actually wonderful :3

    2) Because SLAAC requires a /64 per LAN to work, and IPv6 without SLAAC is more cumbersome to set up and use e.g. for a VPN (you will need to statically assign everything, or set up DHCPv6).
