Creates a new IPv6 address from eight 16-bit segments.

The result will represent the IP address a:b:c:d:e:f:g:h.

Examples

use std::net::Ipv6Addr;

let addr = Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff);

Returns the eight 16-bit segments that make up this address.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).segments(),
           [0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff]);

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

This property is defined in RFC 4291.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unspecified(), false);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0).is_unspecified(), true);

Returns true if this is a loopback address (::1).

This property is defined in RFC 4291.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_loopback(), false);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0x1).is_loopback(), true);

Returns true if the address appears to be globally routable.

The following return false:

• the loopback address
• link-local, site-local, and unique local unicast addresses
• interface-, link-, realm-, admin- and site-local multicast addresses

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_global(), true);
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 0x1).is_global(), false);
    assert_eq!(Ipv6Addr::new(0, 0, 0x1c9, 0, 0, 0xafc8, 0, 0x1).is_global(), true);
}

Returns true if this is a unique local address (fc00::/7).

This property is defined in RFC 4193.

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unique_local(),
               false);
    assert_eq!(Ipv6Addr::new(0xfc02, 0, 0, 0, 0, 0, 0, 0).is_unique_local(), true);
}

Returns true if the address is unicast and link-local (fe80::/10).

This property is defined in RFC 4291.

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unicast_link_local(),
               false);
    assert_eq!(Ipv6Addr::new(0xfe8a, 0, 0, 0, 0, 0, 0, 0).is_unicast_link_local(), true);
}

Returns true if this is a deprecated unicast site-local address (fec0::/10).

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unicast_site_local(),
               false);
    assert_eq!(Ipv6Addr::new(0xfec2, 0, 0, 0, 0, 0, 0, 0).is_unicast_site_local(), true);
}

Returns true if this is an address reserved for documentation (2001:db8::/32).

This property is defined in RFC 3849.

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_documentation(),
               false);
    assert_eq!(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0).is_documentation(), true);
}

Returns true if the address is a globally routable unicast address.

The following return false:

• the loopback address
• the link-local addresses
• the (deprecated) site-local addresses
• unique local addresses
• the unspecified address
• the address range reserved for documentation

Examples

#![feature(ip)]

use std::net::Ipv6Addr;

fn main() {
    assert_eq!(Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0).is_unicast_global(), false);
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_unicast_global(),
               true);
}

Returns the address's multicast scope if the address is multicast.

Examples

#![feature(ip)]

use std::net::{Ipv6Addr, Ipv6MulticastScope};

fn main() {
    assert_eq!(Ipv6Addr::new(0xff0e, 0, 0, 0, 0, 0, 0, 0).multicast_scope(),
                             Some(Ipv6MulticastScope::Global));
    assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).multicast_scope(), None);
}

Returns true if this is a multicast address (ff00::/8).

This property is defined by RFC 4291.

Examples

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0).is_multicast(), true);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).is_multicast(), false);

Converts this address to an IPv4 address. Returns None if this address is neither IPv4-compatible or IPv4-mapped.

::a.b.c.d and ::ffff:a.b.c.d become a.b.c.d

use std::net::{Ipv4Addr, Ipv6Addr};

assert_eq!(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0).to_ipv4(), None);
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0xffff, 0xc00a, 0x2ff).to_ipv4(),
           Some(Ipv4Addr::new(192, 10, 2, 255)));
assert_eq!(Ipv6Addr::new(0, 0, 0, 0, 0, 0, 0, 1).to_ipv4(),
           Some(Ipv4Addr::new(0, 0, 0, 1)));

Returns the sixteen eight-bit integers the IPv6 address consists of.

use std::net::Ipv6Addr;

assert_eq!(Ipv6Addr::new(0xff00, 0, 0, 0, 0, 0, 0, 0).octets(),
           [255, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]);
