.be country-code

i

.be 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

.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.

2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: auth00.ns.be.uu.net, auth50.ns.be.uu.net.

#6
✓ 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.

One address family in one network

all IPv6 addresses are in 2001:600:1c0::/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 (AS702 (UUNET - Verizon Business, US): 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
i

All nameserver names under .net

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.
