DNS Reverse configuration
Hi list, My question is related to reverse DNS configuration. I have access to the domain object of a /16 with 4 NS configured (say ns1 2 3 4). We don't have access to the NS servers. We are LIR for the /16. We announce the last x.x.255.0/24 of this /16 via our ASN. We want to create reverse DNS records for the last x.x.255.0/24. The problem is that, the owner of the NS don't want to delegate the /24 reverse. They just don't want to touch the NS. My question is : can I create a new domain object only for this x.x.255.0/24, so that I can create reverse records on our own NS and only for this /24. Is this is clear enough ? Thanks Regards

Unfortunately, this is not possible. The presence of NS records at the delegation point of the /16-sized allocation (x.x.in-addr.arpa) occludes (hides) NS records below it. This is how the DNS protocol works. You'll have to find some way to convince the operator of the name servers to add a delegation for you on their name servers. Regards, Anand Buddhdev RIPE NCC
Hi! As long as the /16 exists in RIPEdb as a /16, the NCC will only delegate to the NSes for the /16 reverse zone. Individual /24 reverse zones must be delegated in the downstream NSes. /david

No. DNS works strictly hierarchically, so the delegation for the /24 has to be put in the /16 zone. If the current DNS operator of the /16 zone does not want to do that job, move it elsewhere...
