## NAME

dnsjit.core.object.ip6 - An IPv6 packet

## DESCRIPTION

An IPv6 packet that usually can be found in the object chain after parsing with, for example, Layer filter.

### Attributes

- flow

  4 bits version, 8 bits TC and 20 bits flow-ID.

- plen

  Payload length (as in the IPv6 header).

- nxt

  Next header.

- hlim

  Hop limit.

- src

  Source address.

- dst

  Destination address.

- is\_frag

  1 bit, set if packet is a fragment.

- have\_rtdst

  1 bit, set if *rtdst* is set.

- frag\_offlg

  Offset, reserved, and flag taken from the fragment header.

- frag\_ident

  Identification taken from the fragment header.

- rtdst

  Destination address found in the routing extension header.

- hlen

  The length of extension headers, in bytes.

- payload

  A pointer to the payload.

- len

  The length of the payload.

- pad\_len

  The length of padding found, if any.

### Functions

- **Ip6:type**()

  Return the textual type of the object.

- **Ip6:prev**()

  Return the previous object.

- **Ip6:cast**()

  Cast the object to the underlining object module and return it.

- **Ip6:uncast**()

  Cast the object to the generic object module and return it.

- **Ip6:copy**()

  Make a copy of the object and return it.

- **Ip6:free**()

  Free the object, should only be used on copies or otherwise allocated.

- **Ip6:source**(pretty)

  Return the IPv6 source as a string. If *pretty* is true then return an easier to read IPv6 address.

- **Ip6:destination**(pretty)

  Return the IPv6 destination as a string. If *pretty* is true then return an easier to read IPv6 address.
