public ushort AnswerCount { get; set; }

Property Value

ushort

AuthoritativeAnswer

Gets or sets a value indicating whether the responding server is authoritative for the domain name in the query.

public bool AuthoritativeAnswer { get; set; }

Property Value

bool

Id

Gets or sets the identifier for the DNS message header, used to match requests with responses.

public ushort Id { get; set; }

Property Value

ushort

NameserverCount
