Constructor Details

DefaultDnsOptEcsRecord

public DefaultDnsOptEcsRecord(int maxPayloadSize,
 int extendedRcode,
 int version,
 int srcPrefixLength,
 byte[] address)

Creates a new instance.

Parameters:

maxPayloadSize - the suggested max payload size in bytes

extendedRcode - the extended rcode

version - the version

srcPrefixLength - the prefix length

address - the bytes of the InetAddress to use

DefaultDnsOptEcsRecord

public DefaultDnsOptEcsRecord(int maxPayloadSize,
 int srcPrefixLength,
 byte[] address)

Creates a new instance.

Parameters:

maxPayloadSize - the suggested max payload size in bytes

srcPrefixLength - the prefix length

address - the bytes of the InetAddress to use

DefaultDnsOptEcsRecord

public DefaultDnsOptEcsRecord(int maxPayloadSize,
 InternetProtocolFamily protocolFamily)

Creates a new instance.

Parameters:

maxPayloadSize - the suggested max payload size in bytes

protocolFamily - the InternetProtocolFamily to use. This should be the same as the one used to send the query.
