Hello, The reverse DNS is not working for subnet R203382 (2401:e800:101::/48), I have configured the zone delegation to ns5.he.net, and it works on the ns5.he.net, but not on global network. Dig from ns5.he.net

It seems SixXS delegated the prefix to ns5.he.net, but Netnam did not delegated this prefix to SixXS.
