Detailed Description

Represents an IPv4 address (of type XXX.XXX.XXX.XXX)

Constructor & Destructor Documentation

◆ IPv4Address() [1/4]

pcpp::IPv4Address::IPv4Address ( )
inline

A default constructor that creates an instance of the class with unspecified/zero address

◆ IPv4Address() [2/4]

pcpp::IPv4Address::IPv4Address ( uint32_t  addrAsInt)
inline

A constructor that creates an instance of the class out of 4-byte integer value.

Parameters
[in]addrAsIntThe address as 4-byte integer in network byte order

◆ IPv4Address() [3/4]

pcpp::IPv4Address::IPv4Address ( const uint8_t  bytes[4])
inline

A constructor that creates an instance of the class out of 4-byte array.

Parameters
[in]bytesThe address as 4-byte array in network byte order

◆ IPv4Address() [4/4]

pcpp::IPv4Address::IPv4Address ( const std::string &  addrAsString)

A constructor that creates an instance of the class out of std::string value If the string doesn't represent a valid IPv4 address, an instance will store an unspecified address

Parameters
[in]addrAsStringThe std::string representation of the address

Member Function Documentation

◆ isMulticast()

bool pcpp::IPv4Address::isMulticast ( ) const

Determine whether the address is a multicast address

Returns
True if an address is multicast

◆ isValid()

bool pcpp::IPv4Address::isValid ( ) const
inline

Determine whether the address is valid (it's not an unspecified/zero)

Returns
True if an address is not unspecified/zero

◆ matchNetwork() [1/2]

bool pcpp::IPv4Address::matchNetwork ( const IPv4Network network) const

Checks whether the address matches a network.

Parameters
networkAn IPv4Network network
Returns
True if the address matches the network or false otherwise

◆ matchNetwork() [2/2]

bool pcpp::IPv4Address::matchNetwork ( const std::string &  network) const

Checks whether the address matches a network. For example: this method will return true for address 10.1.1.9 and network which is one of: 10.1.1.1/24, 10.1.1.1/255.255.255.0 Another example: this method will return false for address 11.1.1.9 and network which is one of: 10.1.1.1/16, 10.1.1.1/255.255.0.0

Parameters
[in]networkA string in one of these formats:
  • X.X.X.X/Y where X.X.X.X is a valid IP address and Y is a number between 0 and 32
  • X.X.X.X/Y.Y.Y.Y where X.X.X.X is a valid IP address and Y.Y.Y.Y is a valid netmask
Returns
True if the address matches the network or false if it doesn't or if the network is invalid

◆ matchSubnet() [1/2]

bool pcpp::IPv4Address::matchSubnet ( const IPv4Address subnet,
const std::string &  subnetMask 
) const
Deprecated:
This method is deprecated, please use matchNetwork(const IPv4Network& network)

◆ matchSubnet() [2/2]

bool pcpp::IPv4Address::matchSubnet ( const IPv4Address subnet,
const IPv4Address subnetMask 
) const
Deprecated:
This method is deprecated, please use matchNetwork(const IPv4Network& network)

◆ operator!=()

bool pcpp::IPv4Address::operator!= ( const IPv4Address rhs) const
inline

Overload of the not-equal-to operator

Parameters
[in]rhsThe object to compare with
Returns
True if the addresses are not equal, false otherwise

◆ operator<()

bool pcpp::IPv4Address::operator< ( const IPv4Address rhs) const
inline

Overload of the less-than operator

Parameters
[in]rhsThe object to compare with
Returns
True if the address value is lower than the other address value, false otherwise

◆ operator==()

bool pcpp::IPv4Address::operator== ( const IPv4Address rhs) const
inline

Overload of the equal-to operator

Parameters
[in]rhsThe object to compare with
Returns
True if the addresses are equal, false otherwise

◆ toBytes()

const uint8_t* pcpp::IPv4Address::toBytes ( ) const
inline

Returns a pointer to 4-byte array representing the IPv4 address

◆ toInt()

uint32_t pcpp::IPv4Address::toInt ( ) const
inline

Converts the IPv4 address into a 4B integer

Returns
a 4B integer in network byte order representing the IPv4 address

◆ toString()

std::string pcpp::IPv4Address::toString ( ) const

Returns a std::string representation of the address

Returns
A string representation of the address

Member Data Documentation

◆ MulticastRangeLowerBound

const IPv4Address pcpp::IPv4Address::MulticastRangeLowerBound
static

A static values representing the lower and upper bound of IPv4 multicast ranges. The bounds are inclusive. MulticastRangeLowerBound is initialized to "224.0.0.0". MulticastRangeUpperBound is initialized to "239.255.255.255". In order to check whether the address is a multicast address the isMulticast method can be used.

◆ Zero

const IPv4Address pcpp::IPv4Address::Zero
static

A static value representing a zero value of IPv4 address, meaning address of value "0.0.0.0" Notice this value can be omitted in the user code because the default constructor creates an instance with an unspecified/zero address. In order to check whether the address is zero the method isValid can be used
