Struct std::net::Ipv4Addr

pub struct Ipv4Addr { /* private fields */ }
Expand description

An IPv4 address.

IPv4 addresses are defined as 32-bit integers in IETF RFC 791. They are usually represented as four octets.

See IpAddr for a type encompassing both IPv4 and IPv6 addresses.

§Textual representation

Ipv4Addr provides a FromStr implementation. The four octets are in decimal notation, divided by . (this is called “dot-decimal notation”). Notably, octal numbers (which are indicated with a leading 0) and hexadecimal numbers (which are indicated with a leading 0x) are not allowed per IETF RFC 6943.

§Examples

use std::net::Ipv4Addr;

let localhost = Ipv4Addr::new(127, 0, 0, 1);
assert_eq!("127.0.0.1".parse(), Ok(localhost));
assert_eq!(localhost.is_loopback(), true);
assert!("012.004.002.000".parse::<Ipv4Addr>().is_err()); // all octets are in octal
assert!("0000000.0.0.0".parse::<Ipv4Addr>().is_err()); // first octet is a zero in octal
assert!("0xcb.0x0.0x71.0x00".parse::<Ipv4Addr>().is_err()); // all octets are in hex

impl Ipv4Addr

1.0.0 (const: 1.32.0) · source

pub const fn new(a: u8, b: u8, c: u8, d: u8) -> Ipv4Addr

Creates a new IPv4 address from four eight-bit octets.

The result will represent the IP address a.b.c.d.

pub const BITS: u32 = 32u32

🔬This is a nightly-only experimental API. (ip_bits #113744)

The size of an IPv4 address in bits.

§Examples
#![feature(ip_bits)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::BITS, 32);
Run
const: unstable · source

pub fn to_bits(self) -> u32

🔬This is a nightly-only experimental API. (ip_bits #113744)

Converts an IPv4 address into a u32 representation using native byte order.

Although IPv4 addresses are big-endian, the u32 value will use the target platform’s native byte order. That is, the u32 value is an integer representation of the IPv4 address and not an integer interpretation of the IPv4 address’s big-endian bitstring. This means that the u32 value masked with 0xffffff00 will set the last octet in the address to 0, regardless of the target platform’s endianness.

§Examples
#![feature(ip_bits)]
use std::net::Ipv4Addr;

let addr = Ipv4Addr::new(0x12, 0x34, 0x56, 0x78);

Returns true if this address part of the 198.18.0.0/15 range, which is reserved for network devices benchmarking. This range is defined in IETF RFC 2544 as 192.18.0.0 through 198.19.255.255 but errata 423 corrects it to 198.18.0.0/15.

pub fn is_reserved(&self) -> bool

🔬This is a nightly-only experimental API. (ip #27709)

Returns true if this address is reserved by IANA for future use. IETF RFC 1112 defines the block of reserved addresses as 240.0.0.0/4. This range normally includes the broadcast address 255.255.255.255, but this implementation explicitly excludes it, since it is obviously not reserved for future use.

§Warning

As IANA assigns new addresses, this method will be updated. This may result in non-reserved addresses being treated as reserved in code that relies on an outdated version of this method.

§Examples
#![feature(ip)]
use std::net::Ipv4Addr;

assert_eq!(Ipv4Addr::new(240, 0, 0, 0).is_reserved(), true);
