.be country-code

i

.be is delegated in the root zone and DNSSEC-signed.

Registration data not available

No registration data via RDAP: the registry of .be offers no RDAP service. Many ccTLD registries don't offer RDAP; check the registry's WHOIS instead.

✓ 4 nameservers #6

Delegated to ns.oma.be, ns2.oma.be, ns3.oma.be, ns4.oma.be.
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns4.oma.be. ns.oma.be, ns2.oma.be, ns3.oma.be report NS ns.oma.be ns2.oma.be ns3.oma.be.

#7
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✗

Nameserver names don't resolve

These nameservers have no A or AAAA record, so they can't be reached (lame delegation): ns4.oma.be.

#9
✓ Nameservers in different networks #10

The nameservers are spread over 3 IPv4 /24s and 0 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS2611 (BELNET - BELNET, BE): 3 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 .be

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
i

Partly IPv6

These nameservers have no IPv6 address: ns.oma.be, ns2.oma.be, ns3.oma.be.
