    #1
  • ✓ TLD delegated and signed #2
    .nl is delegated in the root zone and DNSSEC-signed.
  • i
    Expiry date not published
    The registry does not publish the expiry date in RDAP. Check it with your registrar.
    #3
  • i
    No transfer lock

Checks

  • ✓ 3 nameservers #6
    Delegated to linheb18.ikoula.com, ns1.ikoula.nl, ns2.host2vps.com.
  • ✓ Parent and zone agree #7
    The parent delegation and the zone's NS records list the same nameservers.
  • ✓ No glue needed #8
    All nameservers are outside the zone, so no glue records are needed.
  • ✓ 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 3 IPv4 /24s and 1 IPv6 /48.
  • i
    All nameservers in one AS
    All nameserver addresses are announced by one network operator (AS21409 (IKOULA - Ikoula Net SAS, FR): 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 .com, .nl.
  • i
    Partly IPv6
    These nameservers have no IPv6 address: ns1.ikoula.nl, ns2.host2vps.com.
