| 2 | IP addressing - nodetracker | Each Super Node nodetracker instance MUST be able to establish connectivity, outbound over a unique, IPv4 or IPv6 address. The IP address used for the nodetracker MUST be one of the two IP addresses (IPv4, or IPv6) employed by zend i.e. it does not need to be an additional unique IP address. |
| 3 | DNS entries | DNS entries MUST be present for BOTH the IPv4 AND IPv6 addresses which are assigned to zend - therefore BOTH an A AND AAAA record for the Super Node FQDN are required |

| 7 | Challenge response times | Super Nodes MUST be capable of completing challenges in 100 seconds or less |

| 9 | Uptime | Super Nodes MUST achieve a minimum uptime of 96% of the reward period to qualify for rewards (for that specific reward period) |
