Detailed Description

This is an interface (abstract class) implemented in the IP layers (IPv4Layer and IPv6Layer). It provides methods to fetch the source and destination IP addresses in an abdtract way that hides the IP type (IPv4 or IPv6). This is useful for use-cases in which the IP type doesn't matter. For example: if you're only interested in printing the IP address the IP type shouldn't matter.

Member Function Documentation

◆ getDstIPAddress()

virtual IPAddress pcpp::IPLayer::getDstIPAddress ( ) const

pure virtual

An abstract method to get the destination IP address

Returns: An IPAddress object containing the destination address

Implemented in pcpp::IPv6Layer, and pcpp::IPv4Layer.

◆ getIPVersion()

static ProtocolType pcpp::IPLayer::getIPVersion	(	uint8_t const *	data,
		size_t	dataLen
	)

static

Get the IP version of a given packet data.

The buffer is expected to start with the IP header and contain at least the first byte of it. The method will recognize IPv4 and IPv6 headers and return the respective protocol constant. If the IP version is not recognized or the buffer is malformed, UnknownProtocol will be returned.

Parameters

[in]	data	A pointer to the packet data
[in]	dataLen	The length of the packet data in bytes

Returns: A ProtocolType representing the IP version of the packet data.

◆ getSrcIPAddress()

virtual IPAddress pcpp::IPLayer::getSrcIPAddress ( ) const
