We are Global One Jordan and we own the 194.165.128.0 /19 group of class C IP addresses. We need to have the delegation of reverse addressing for these network addresses. What do we need to do in order to get that delegation. my understanding is that in this situation you will need to request delegation of the reverse mapping for each /24 from RIPE NCC. I assume that you want to further delegate the reverse mapping of smaller
Hi Nader, parts of this space to be administered by your customers. There is a technique to support delegation of reverse mapping zones that allows delegation for prefixes longer than /24, i.e. sub-C using classfull terminology (and a description has been published as an RFC this year). Unfortunately there is no technique to really support non-byte-boundary delegation for reverse mapping for /23 or shorter prefixes - well, at least no way that I know of.
