    2 nameservers
    Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: dns40.telus.ca, dns40.telus.com.
    #6
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ Glue present and correct #8
    Glue is published for the nameservers inside the zone: dns40.telus.com.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • i
    One address family in one network
    all IPv6 addresses are in 2001:56b:d::/48, while the other address family is spread over several networks.
    #10
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS852 (ASN852 - TELUS Communications Inc., CA): 4 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • ✓ Nameserver names under 2 TLDs #12
    Nameserver names use the TLDs .ca, .com.
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
