org.xbill.DNS.OPTRecord
| OPTRecord | | public class OPTRecord extends Record (Code) | | Options - describes Extended DNS (EDNS) properties of a Message.
No specific options are defined other than those specified in the
header. An OPT should be generated by Resolver.
EDNS is a method to extend the DNS protocol while providing backwards
compatibility and not significantly changing the protocol. This
implementation of EDNS is mostly complete at level 0.

| Constructor Summary | |
| | OPTRecord()
| | public | OPTRecord(int payloadSize, int xrcode, int version, int flags, List options)
Creates an OPT Record. | | public | OPTRecord(int payloadSize, int xrcode, int version, int flags)
Creates an OPT Record with no data. | | public | OPTRecord(int payloadSize, int xrcode, int version)
Creates an OPT Record with no data. |
| OPTRecord | | public OPTRecord(int payloadSize, int xrcode, int version, int flags, List options)(Code) | | Creates an OPT Record. This is normally called by SimpleResolver, but can
also be called by a server.
Parameters:
payloadSize - The size of a packet that can be reassembled on the sending host.
Parameters:
xrcode - The value of the extended rcode field. This is the upper16 bits of the full rcode.
Parameters:
flags - Additional message flags.
Parameters:
version - The EDNS version that this DNS implementation supports.This should be 0 for dnsjava.
Parameters:
options - The list of options that comprise the data field. Thereare currently no defined options.
