Detailed Description

IPv4 address value type.

Stores an IPv4 address in network byte order. Provides construction from individual octets and conversion to string representation.

auto addr = idfxx::net::ip4_addr(192, 168, 1, 1);
auto s = idfxx::to_string(addr); // "192.168.1.1"

Constructor & Destructor Documentation

ip4_addr() [1/3]

constexpr idfxx::net::ip4_addr::ip4_addr ( )

constexprdefaultnoexcept

Constructs a zero-initialized IPv4 address (0.0.0.0).

ip4_addr() [2/3]

constexpr idfxx::net::ip4_addr::ip4_addr ( uint32_t  addr )

inlineexplicitconstexprnoexcept

Parameters

addr	The IPv4 address in network byte order.

Definition at line 70 of file net.hpp.

ip4_addr() [3/3]

constexpr idfxx::net::ip4_addr::ip4_addr ( uint8_t  a, uint8_t  b, uint8_t  c, uint8_t  d  )

inlineconstexprnoexcept

Constructs an IPv4 address from individual octets.

Parameters

a	First octet (most significant).
b	Second octet.
c	Third octet.
d	Fourth octet (least significant).

Member Function Documentation

addr()

constexpr uint32_t idfxx::net::ip4_addr::addr ( ) const

inlineconstexprnoexcept

Returns the raw address value in network byte order.

Returns

The IPv4 address as a 32-bit integer in network byte order.

Definition at line 92 of file net.hpp.

is_any()

constexpr bool idfxx::net::ip4_addr::is_any ( ) const

inlineconstexprnoexcept

Tests whether this is a zero (unset) address.

Returns

True if the address is 0.0.0.0.

Definition at line 99 of file net.hpp.

operator==()

constexpr bool idfxx::net::ip4_addr::operator== ( const ip4_addr &  ) const

constexprdefaultnoexcept

Compares two IPv4 addresses for equality.

parse()

static std::optional< ip4_addr > idfxx::net::ip4_addr::parse ( std::string_view  s )

staticnoexcept

Parses an IPv4 address from dotted-decimal notation.

Accepts addresses in the form "a.b.c.d" where each octet is a decimal value from 0 to 255 with no leading zeros.

Parameters

s	The string to parse (e.g. "192.168.1.1").

Returns

The parsed address, or std::nullopt if the string is not valid.

auto addr = idfxx::net::ip4_addr::parse("192.168.1.1");
if (addr) {
    // use *addr
}
