Hi,

I am using native IPv6 on my Linode, not a tunnel broker. Searching this forum and Linode docs, so far I can only find references to when the tunnel terminates on a Linode. Most of what I find pre-dates native IPv6 support, so I decided to ask here.

I do use a tunnel broker elsewhere, and have a /48 prefix. It's from Hurricane Electric, and I can delegate rDNS. I'd like these addresses to show up as part of my domain.

Before I run my named on my linode, I'd like to know if it is now possible to have Linode DNS server accept Reverse Delegation for address in this /48 range? Linode DNS likes the AAAA records just fine, and for Linode assigned IPv6 addresses, Reverse Delegation is working too.

If dig is to be trusted, I have successfully delegated to e.g. ns1.linode.com. However, I can't get ReverseDNS to accept an address from this prefix.

Should this be possible with Linode DNS?

Thanks

In order to do reverse DNS for an IPv6 address or range that isn't assigned to your Linode, such as a /48 from Hurricane Electric's TunnelBroker service, you have to create a slave zone in the DNS Manager for the ip6.arpa name that matches your assigned range. It's not possible to use the reverse DNS link from the Remote Access tab, as that's only for addresses assigned to your Linode. If you're not familiar or comfortable with running your own nameserver and slaving our nameservers off of it, I'd recommend just using HE's own DNS service to handle the reverse DNS for the range.

Thanks for your response



Thanks.

If I go this route, is it possible to split the one example.org across multiple (authoritative?) name servers? That is use Linode DNS for my domain (IPv4 and Linode IPv6) while having just the /48?

Thanks,

Reverse DNS and forward DNS are completely separate, so there won't be any issues. In HE's DNS panel, you'd make a zone for 8.b.d.0.0.7.4.0.1.0.0.2.ip6.arpa (iirc, they have a helper for this; it's just the range fully specified, reversed, and one hex character per label), and add PTR records that point to your desired DNS name, such as foobar.example.com. Then in the Linode DNS Manager, you'd make an A/AAAA record for foobar.example.com that points to the IPv6 address you just made the PTR record for. As far as DNS is concerned, they're completely separate domains, so there won't be any issues.

Do I delegate rDNS to Linode name servers or he.dns.net names servers or?

Thanks again

You'd delegate to HE's nameservers; there's a link in the TunnelBroker interface that'll set them all for you.

Thanks, now I wait....

I removed the AAAA records from Linode initially (since added back.) At first I thought HE would create them on its server. It looks like they only setup reverse. It looks like one can "edit the zone" for the active domain and create A, AAAA, MX etc records if needed.
