All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`extendedRcode()`	Returns the `EXTENDED-RCODE` which is encoded into `DnsRecord.timeToLive()`.
`int`	`flags()`	Returns the 16-bit `flags` field which is encoded into the lower 16 bits of `DnsRecord.timeToLive()`, as laid out by RFC 6891.
`int`	`version()`	Returns the `VERSION` which is encoded into `DnsRecord.timeToLive()`.

- Method Detail
  - extendedRcode
```
int extendedRcode()
```
    Returns the EXTENDED-RCODE which is encoded into DnsRecord.timeToLive().
  - version
```
int version()
```
    Returns the VERSION which is encoded into DnsRecord.timeToLive().
  - flags
```
int flags()
```
    Returns the 16-bit flags field which is encoded into the lower 16 bits of DnsRecord.timeToLive(), as laid out by RFC 6891.
    DO, defined by RFC 3225, is the most significant bit of that field, so (flags() & 0x8000) != 0 tests for DNSSEC OK. Further bits are assigned by the IANA EDNS Header Flags registry; the remaining bits are Z, which senders set to zero and receivers ignore.
