Sets the ID of this DNS message.

Specified by:

setId in interface DnsMessage

setOpCode

DnsResponse setOpCode(DnsOpCode opCode)

Description copied from interface: DnsMessage

Sets the opCode of this DNS message.

Specified by:

setOpCode in interface DnsMessage

setRecursionDesired

DnsResponse setRecursionDesired(boolean recursionDesired)

Description copied from interface: DnsMessage
