Checks

• i

  .nl is a country-code TLD (ccTLD)

  Country-code TLD: governed by its local registry under national policy, not by an ICANN contract. Registrar accreditation, dispute resolution and RDAP/WHOIS rules are set by the registry.

  #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

  The domain has no transfer lock (status: active). A registrar lock protects against unauthorized transfers.

• ✓ 4 nameservers #6

  Delegated to ns1-09.azure-dns.com, ns2-09.azure-dns.net, ns3-09.azure-dns.org, ns4-09.azure-dns.info.
• ✓ 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 4 IPv4 /24s and 4 IPv6 /48s.
• i

  All nameservers in one AS

  All nameserver addresses are announced by one network operator (AS8075 (MICROSOFT-CORP-MSN-AS-BLOCK - Microsoft Corporation, US): 8 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 4 TLDs #12

  Nameserver names use the TLDs .com, .info, .net, .org.
• ✓ All reachable over IPv6 #13

  Every nameserver has an IPv6 address.

  NSEC
