I have a setup that had 2 DNS servers dns3-master and dns4-slave, in that setup I was able to add reverse delegation on the ripe site, then we had added one more dns server and we made it dns5-slave to the dns3-master.

So why I am getting following errors ?

I have solved my above Problem by adding the reverse subnet into the DNS server so that it can respond to the query from the RIPE.

    I am sorry, but this answer is just not enough to actually understand what you did. Please add the actual zone files you used, both forward and reverse, as well as a description of what you were trying to do, and the steps you went through. – zkilnbqi Feb 06 '17 at 23:34

As I found this solution resolutive also for me, I would like to add a detailed explanation:

Under each x.x.x.in-addr.arpa zone you must create NS records pointing to your name servers.

When RIPE is doing a check before allowing you to create the PTR record, it would like to find NS records pointing to your nameservers.

If NS records are not configured you will receive a ***ERROR: No name servers found at child.

I hope it may help other persons.
