Checks

  • ✓ 5 nameservers #6
    Delegated to tv-ns1.teamviewer.com, tv-ns2.teamviewer.com, tv-ns3.teamviewer.com, tv-ns4.teamviewer.com, tv-ns5.teamviewer.com.
  • ✓ 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: tv-ns1.teamviewer.com, tv-ns2.teamviewer.com, tv-ns3.teamviewer.com, tv-ns4.teamviewer.com, tv-ns5.teamviewer.com.
  • ✓ All names resolve #9
    Every nameserver name has an address and is not an alias.
  • ✓ Nameservers in different networks #10
    The nameservers are spread over 5 IPv4 /24s and 5 IPv6 /48s.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS42388 (ANX-CLOUDDNS - Anexia Cloud Solutions GmbH, AT): 10 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.
    #11
  • i
    All nameserver names under .com
    All nameserver names are under one TLD, so a problem with that TLD also makes the nameservers unreachable. Some operators use names under two TLDs for extra resilience.
    #12
  • ✓ All reachable over IPv6 #13
    Every nameserver has an IPv6 address.
