-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, section 4.2.2 of the ENRP draft defines that the ENRP identifier must be "as unique as possible in the operational scope" and recommends a random number. But what happens when two nameservers choose the same number? Although the probability for choosing the same random 32-bit numbers is low (an attacker may increase it), this may happen. And in this case, it will cause at least severe problems for the takeover procedure. If one of the equal-numbered NSs fails, the other one will answer a PEER_INIT_TAKEOVER with a PEER_PRESENCE and therefore abort the takeover.
