What do you mean your own branded/assigned? If you mean the business level feature which you have to contact support for, I don't see why not

it'll pick others if there's any conflict or issue. If you try to preset them before you add the zone/domain in CF it'll also pick different ones. You always want to use the ones it gives you on zone creation

As long as you set them up right

The Computer Science HallOP•10/31/24, 2:56 PM

you created it off the reverse and made ptr records?

Chaika•10/31/24, 2:57 PM

looks sane

CChaika you created it off the reverse and made ptr records?

The Computer Science HallOP•10/31/24, 2:57 PM

yes

The Computer Science HallOP•10/31/24, 2:57 PM

those are reverse zones for the IPv6 Addresses

Chaika•10/31/24, 2:58 PM

yea, as long as they're the right names should activate fine

not sure I understand how their setup is supposed to work fully, but if it's supposed to be simple delegation of the /48 and /64 to your own ns, it's not

Just a question how do you obtain

TThe Computer Science Hall Just a question how do you obtain `ip6-servers.arpa`

See RFC 5855

IETF Datatracker

RFC 5855: Nameservers for IPv4 and IPv6 Reverse Zones

This document specifies a stable naming scheme for the nameservers that serve the zones IN-ADDR.ARPA and IP6.ARPA in the DNS. These zones contain data that facilitate reverse mapping (address to name). This memo documents an Internet Best Current Practice.

The arpa zones here work on DNS.he.net, they have a lock with the soa record and I can set ns records for the arpa zones
