Detailed Description

A class representing IPv6 network definition

Constructor & Destructor Documentation

IPv6Network() [1/3]

pcpp::IPv6Network::IPv6Network	(	const IPv6Address &	address,
		uint8_t	prefixLen
	)

A constructor that creates an instance of the class out of an address representing the network prefix and a prefix length

Parameters

address	An address representing the network prefix. If the address is invalid std::invalid_argument exception is thrown
prefixLen	A number between 0 and 128 representing the prefix length. If another value is provided std::invalid_argument exception is thrown

IPv6Network() [2/3]

pcpp::IPv6Network::IPv6Network	(	const IPv6Address &	address,
		const std::string &	netmask
	)

A constructor that creates an instance of the class out of an address representing the network prefix and a netmask

Parameters

address	An address representing the network prefix. If the address is invalid std::invalid_argument exception is thrown
netmask	A string representing a netmask in valid IPv6 format, for example: ffff:ffff::. Please notice that netmasks that start with zeros are invalid, for example: 0:ffff::. The only netmask starting with zeros that is valid is all zeros (::). If the netmask is invalid std::invalid_argument exception is thrown

IPv6Network() [3/3]

pcpp::IPv6Network::IPv6Network

(

const std::string &

addressAndNetmask

)

A constructor that creates an instance of the class out of a string representing the network prefix and a prefix length or a netmask

Parameters

addressAndNetmask

A string in one of these formats: IPV6_ADDRESS/Y where IPV6_ADDRESS is a valid IPv6 address representing the network prefix and Y is a number between 0 and 128 representing the network prefix IPV6_ADDRESS/IPV6_NETMASK where IPV6_ADDRESS is a valid IPv6 address representing the network prefix and IPV6_NETMASK is a valid IPv6 netmask For any invalid value std::invalid_argument is thrown

Member Function Documentation

getHighestAddress()

IPv6Address pcpp::IPv6Network::getHighestAddress

(

)

const

Returns

The highest IPv6 address in this network, for example: the highest address in 3546::/16 is 3546:ffff:ffff:ffff:ffff:ffff:ffff:ffff

getLowestAddress()

IPv6Address pcpp::IPv6Network::getLowestAddress

(

)

const

Returns

The lowest non-reserved IPv6 address in this network, for example: the lowest address in 3546::/16 is 3546::1

getNetmask()

std::string pcpp::IPv6Network::getNetmask ( ) const

inline

Returns

The netmask, for example: the netmask of 3546::/16 is ffff::

getNetworkPrefix()

IPv6Address pcpp::IPv6Network::getNetworkPrefix ( ) const

inline

Returns

The network prefix, for example: the network prefix of 3546:f321::/16 is 3546::

getPrefixLen()

uint8_t pcpp::IPv6Network::getPrefixLen

(

)

const

Returns

The prefix length, for example: the prefix length of 3546::/ffff:: is 16

getTotalAddressCount()

uint64_t pcpp::IPv6Network::getTotalAddressCount

(

)

const

Returns

The number of addresses in this network, for example: the number of addresses in 16ff::/120 is 256. If the number of addresses exceeds the size of uint64_t a std::out_of_range exception is thrown

includes() [1/2]

bool pcpp::IPv6Network::includes

(

const IPv6Address &

address

)

const

Parameters

address

An IPv6 address

Returns

True is the address belongs to the network, false otherwise or if the address isn't valid

includes() [2/2]

bool pcpp::IPv6Network::includes

(

const IPv6Network &

network

)

const

Parameters

network

An IPv6 network

Returns

True is the input network is completely included within this network, false otherwise, for example: 3546::/64 includes 3546::/120 but doesn't include 3546::/16

toString()

std::string pcpp::IPv6Network::toString

(

)

const

Returns

A string representation of the network in a format of NETWORK_PREFIX/PREFIX_LEN, for example: fda7:9f81:6c23:275::/64
