Ich verwende Scapy in Python3, um eine DNS -Abfrage anzufordern, aber ich bekomme keine Antwort ⇐ Python

Beim Anfordern von DNS über DNS.Resolver in Python wird eine Antwort erhalten, aber beim Importieren von SCAPAD und eine DNS -Abfrage wurde keine Antwort erhalten. https://github.com/secdev/scapy/archive/master.zip.
