ipv4

Documentation

Overview

Package ipv4 contains the implementation of the ipv4 network protocol. To use it in the networking stack, this package must be added to the project, and activated on the stack by passing ipv4.ProtocolName (or "ipv4") as one of the network protocols when calling stack.New(). Then endpoints can be created by passing ipv4.ProtocolNumber as the network protocol number when calling Stack.NewEndpoint().

Constants

const (
	// ProtocolName is the string representation of the ipv4 protocol name.
	ProtocolName = "ipv4"

	// ProtocolNumber is the ipv4 protocol number.
	ProtocolNumber = header.IPv4ProtocolNumber
)

Functions

func InternalInterfaces

func InternalInterfaces() (ip, nic string)

InternalInterfaces return internal ip && nic name.

func NewProtocol

func NewProtocol() stack.NetworkProtocol

NewProtocol creates a new protocol ipv4 protocol descriptor. This is exported only for tests that short-circuit the stack. Regular use of the protocol is done via the stack, which gets a protocol descriptor from the init() function below.
