2 nameservers

Two nameservers meet the minimum; RFC 2182 recommends three or more for important zones: ns.as5390.net, ns.euronet.com.

#6
!

NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns.euronet.com; only in the zone: ns.euro.net. ns.as5390.net, ns.euro.net report NS ns.as5390.net ns.euro.net.

#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): ns.euronet.com.

#9
!

Nameservers in one network

all IPv4 addresses are in 83.119.20.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS5390 (EuroNet - Euronet Communications B.V., NL): 2 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, .net.
i

Partly IPv6

These nameservers have no IPv6 address: ns.as5390.net, ns.euro.net.
