Hello everyone,
I have a question for those of you who have BGP announced subnets from 44Net, specifically regarding the configuration of rDNS (PTR) records for each IP address within the subnet.
Recently, I received an allocation of a /24 subnet, which is announced via my Data Center's ASN. Everything is functioning correctly, but I need to configure rDNS for each IP address. This configuration is essential for hosting email servers to prevent potential issues.
Here is a dlint output for my gateway's IP address:
root@eye:~# dlint 1.77.32.44.in-addr.arpa ;; dlint version 1.4.0, Copyright (C) 1998 Paul A. Balyoz pab@domtools.com ;; Dlint comes with ABSOLUTELY NO WARRANTY. ;; This is free software, and you are welcome to redistribute it ;; under certain conditions. Type 'man dlint' for details. ;; command line: /usr/bin/dlint 1.77.32.44.in-addr.arpa ;; flags: inaddr-domain recursive. ;; using dig version 9.9.5 ;; run starting: Fri Jun 7 15:10:37 EEST 2024 ;; ============================================================ ;; Now linting 1.77.32.44.in-addr.arpa ERROR: no name servers found for domain 1.77.32.44.in-addr.arpa

;; Now linting 32.44.in-addr.arpa ;; Checking serial numbers per nameserver ;; 2024060700 ns1.de.ardc.net. ;; 2024060700 ns.ardc.net. ;; 2024060700 a.gw4.uk. ;; 2024060700 ns2.us.ardc.net.
===
Based on this output, I believe that the rDNS setup needs to be handled by the ARDC staff. However, I wanted to confirm this to ensure I proceed correctly.
I reached out to Chris off-list and received the following response:
"You already have the subdomain yo6rzv.ampr.org setup; you can add DNS records under there. For each A record, a PTR record is automatically added in the reverse zone."
From my understanding, this does not fully address my requirements, since for example, if IP Address 44.32.77.2 needs to have the rDNS set to -> something.yo44.net, this will not help.
I am aware that Chris and the ARDC staff are currently handling a high volume of tickets and requests through the portal. Therefore, I am turning to the community for assistance to avoid adding more to their workload.
I appreciate any guidance you can provide and apologize in advance if this question has been addressed previously. I could not find relevant information in my email archive.
Thank you for your assistance.

Hi Razvan,
You can either use the subdomain that you requested and received via the portal: yo6rzv.ampr.org http://yo6rzv.ampr.org/ Any A records you add under that will automatically create a PTR record in the reverse zonefile.
However if you wish to use your own domain then you will need to request reverse DNS is delegated to your servers by opening a ticket on the portal: “Help with DNS"

Razvan,
The easiest way to do this is to request that ARDC staff delegate your rDNS zone to a set of nameservers that you control. That is, set NS records on 77.32.44.in-addr.arpa pointing to your nameservers. Then, you can set them however you want.
You'll need to open a support ticket requesting rDNS delegation. They will send you a document listing the requirements for your nameservers. I would share it, but they haven't published it for some reason, so I'm not sure if they're trying to keep it within a closed group. Once your nameservers are compliant with those requirements, you can provide them your nameserver addresses and the address of at least one PTR record to test and they will (eventually) delegate the zone.
Forewarning: this process has taken an extremely long time in my experience (I just got mine delegated the other day after 5 months of waiting).

Hello Chris, Eric,
I really appreciate your fast responses to my questions.
Chris, I want to apologize for any trouble I've had understanding how the portal works. I’ve added a test A record for an IP address within my subnet, and it’s already updated with rDNS added. This is great.
In the meantime, I have opened a ticket as Eric suggested, and until that is resolved, I will use this method. The new portal features are really cool.
Thank you!

Hi all,
I'm writing up this as a follow up email on my initial request, to let you know that this was resolved as Eric pointed out, the rDNS zone was delegated to myself, and now I'm able to handle my rDNS for each of my IP's within the allocated subnet.
Kudos to Chris, which handled the ticket with professionalism and treated the issue very promptly. Had a very pleasant experience.
So if anybody else is in this sittuation, just raise a ticket, and ARDC Staff will handle it so you can play with the rDNS, but you will need to meet some strict requirements imposed by ARDC (which is normal).
If anybody has any other questions related to this, please feel free to email me directly and I'll provide assistance if needed with the whole process.
Have a great day everyone.
