IPv6 /64 Blocks on Linode

Linode Staff

I understand that by default Linodes only have a single IP address from the 2a01:7e01::/64 subnet and one cannot use any other addresses from that subnet - is this correct?

If that's the case, is it possible to request an assignment of a /64 block to my Linode, as I require separate IPs for different subdomains.

Yes, by default a Linode comes with a single /128 IPv6 address. These addresses are not necessarily always in the same /64, as I can see that my own Linodes are in different /64 pools than the one you mentioned. The exact block that you land in ultimately depends on the datacenter that your Linode is in.

As for assigning an IPv6 /64 block to your Linode, we can absolutely do this! In fact, we can also assign /116 and /56 blocks to a Linode, but for those blocks we do require technical justification before assigning them.

You can find more information about IPv6 and Linode here.

Dear Tom D.

My Linode has a /64 IPv6 block. Now, my use case is a VPN that connects some 50 devices in my LAN assigning each a static IPv6 address.

Now, I plan to run a DNS server using bind9 on two of these IPv6 addresses, but how do I set the reverse DNS? I notice that I can only set rDNS for IPv4 but not for my /64 IPv6 block. Is there a tutorial how to set individual IPv6 addresses their own names, like it-help-desk, sales, management, etc.

I hope to hear from you.
