.SH DESCRIPTION
.PP
.B IP
is an implementation of the Internet Protocol
.RB ( IP )
defined in RFC XXXX.
It implements a datagrams, best effort packet service.  Packets may be
reordered or duplicated in the network before they arrive.
.B IP
generates and checks checksums to catch transmission errors.
.PP
.B IP
is implemented as a
.IR STREAMS (4)
pseudo-driver using the
.BR INET (4)
.B strinet
packet for
.BR "Linux Fast-STREAMS" .
.[
LfS
.]
The
.B strinet
packet translates Linux native
.BR ip (7)
sockets into TPI
.[
TPI Revision 2.0.0
.]
transport provider streams suitable for use with XTI,
.[
xti
.]
.[
xns
.]
(see
.BR xti (3)).
.PP
.B IP
provides one connectionless TPI stream type.  To select the stream,
.I ip_device
can be one of the following:
.TP
.IR /dev/ip " or " /dev/inet/ip
This device provides the
.B IP
protocol services using the T-primitives of the Transport Provider Interface,
.[
TPI Revision 2.0.0
.]
.BR tpi (7),
used for Internet Protocol, as described in
.BR tpi_ip (7).
The
.BR tpi (7)
interface provided on a stream opening this device is suitable for use with
the
.BR xnet (3)
or
.BR xti (3)
library and provides
.B IP
interface using XTI
.[
xti
.]
.[
xns
.]
as described in
.BR xti_ip (3).
.PP
.B IP
provides one socket type for use by the
.BR sockets (3)
library
.BR socket (7)
calls.
.B IP
provides sockets in the protocol family
.BR PF_INET " and " PF_INET6
using the protocol number
.BR IPPROTO_IP .
The
.I socket_type
can be one of the following:
.TP
.B SOCK_PACKET
A standard
.I SOCK_PACKET
socket that preserves message boundaries, does not Nagle, and provides only
best effort unreliable delivery in a connectionless association.  This socket
uses the underlying
.IR Linux \(rg
.B IP
socket implementation,
.BR ip (7),
directly.  See
.BR packet (7)
for more information.

.SH USAGE
.PP
.PP
The following entries in
.B /etc/protosw
provides the information for
.BR socksys (4)
to use the devices:
.sp
.TS
tab(:);
lllllll.
PF_INET:SOCK_PACKET:IPPROTO_IP:/dev/ip:tpi:clts
PF_INET6:SOCK_PACKET:IPPROTO_IP:/dev/ip:tpi:clts
.TE
.PP
For additional information, see
.BR socksys "(4) and " protosw (5).
.\"
.\"
.SH IOCTLS
.PP
All interfaces support a set of management IO controls using
.BR ioctl (2)
and
.BR streamio (7)
.I I_STR
system calls on the
.IR ip_stream ", " ip_xtistr " or " ip_socket .
These management controls are described in
.BR timod (4),
.BR sockmod (4)
and
.BR socksys (4).
See also
.BR ip (7)
for sockets.

.\"
.SH NOTICES
.PP
.B IP
has several implementation.  THis manpage is for
.BR INET (4)
implementation that provides
.BR tpi (7)
access to the
.IR Linux \(rg
NET4 version of
.BR IP .
For more information on the
.IR Linux \(rg
NET4 version, see
.BR ip (7).
