DNS records for DoubleZero users

[packethog]

This was a request from Accelerate. They would prefer not to reference DZ connected endpoints by our vended IP addresses and rather use DNS records for internal communication with their other hosts on DoubleZero.

Can we scope this to include DNS for the DZ core network too please?

[packethog]

What is your ask for infra DNS records? PTRs for traceroutes?

[ben-malbeclabs]

Yes, that would be the primary ask.

[ben-malbeclabs]

Would we also put multicast groups in DNS too?

[packethog]

No one has asked for that so I would say no.

Thinking through this: I don't think this is going to be possible as is given we use RFC1918 space for interconnects and since users are effectively multihomed, we can't safely tell a user's machine to resolve ~16.172.in-addr.arpa via doublezero resolvers.
