Struct std::net::Ipv4Addr1.0.0 [] [src]

pub struct Ipv4Addr { /* fields omitted */ }

Representation of an IPv4 address.

Methods

impl Ipv4Addr
[src]

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

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

Returns the four eight-bit integers that make up this address.

Returns true for the special 'unspecified' address (0.0.0.0).

This property is defined in UNIX Network Programming, Second Edition, W. Richard Stevens, p. 891; see also [ip7] [ip7][http://man7.org/linux/man-pages/man7/ip.7.html]

Returns true if this is a loopback address (127.0.0.0/8).

This property is defined by RFC 1122.

Returns true if this is a private address.

The private address ranges are defined in RFC 1918 and include:

  • 10.0.0.0/8
  • 172.16.0.0/12
  • 192.168.0.0/16

Returns true if the address is link-local (169.254.0.0/16).

This property is defined by RFC 3927.

Unstable (ip #27709)

: extra functionality has not been scrutinized to the level that it should be stable

Returns true if the address appears to be globally routable. See iana-ipv4-special-registry.

The following return false:

  • private address (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16)
  • the loopback address (127.0.0.0/8)
  • the link-local address (169.254.0.0/16)
  • the broadcast address (255.255.255.255/32)
  • test addresses used for documentation (192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24)
  • the unspecified address (0.0.0.0)

Returns true if this is a multicast address (224.0.0.0/4).

Multicast addresses have a most significant octet between 224 and 239, and is defined by RFC 5771.

Returns true if this is a broadcast address (255.255.255.255).

A broadcast address has all octets set to 255 as defined in RFC 919.

Returns true if this address is in a range designated for documentation.

This is defined in RFC 5737:

  • 192.0.2.0/24 (TEST-NET-1)
  • 198.51.100.0/24 (TEST-NET-2)
  • 203.0.113.0/24 (TEST-NET-3)

Converts this address to an IPv4-compatible IPv6 address.

a.b.c.d becomes ::a.b.c.d

Converts this address to an IPv4-mapped IPv6 address.

a.b.c.d becomes ::ffff:a.b.c.d
