Hostname haben rDNS:
PHP:
host 2a03:4000:7:16:c::30
0.3.0.0.0.0.0.0.0.0.0.0.c.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.2.ip6.arpa domain name pointer ns3.xxxxxxxxxxx.com.

Haben die Hostnamen eingetragene v6 Adressen im DNS? (Also AAAA Records?) Dann sollte die Fehlermeldungen verschwinden.

"dig aaaa ns1.xxxxxxxxxxx.com"

Ist IPv6 und IPv4 vorhanden wird v6 bevorzugt genommen.
