Problems with NXT records, as specified in RFC 2535, are identified. One solution, the NO record, is presented. The NO record differ from the NXT record by using a cryptographic hash value instead of the domain name. This prevent an adversery from collecting information by 'chaining' through a zone. It also remove delegation point concerns in NXT records. The document also describe hash truncation and record merging that reduces storage/network load.}, }
