# Struct std::net::Ipv6Addr 1.0.0 [−] [src]

    pub struct Ipv6Addr {
        // some fields omitted
    }

Representation of an IPv6 address.

## Methods

### `impl Ipv6Addr`
[src]

#### `fn new(a: u16, b: u16, c: u16, d: u16, e: u16, f: u16, g: u16, h: u16) -> Ipv6Addr`

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.

#### `fn segments(&self) -> [u16; 8]`

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

#### `fn is_unspecified(&self) -> bool`
1.7.0

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

This property is defined in RFC 6890.

#### `fn is_loopback(&self) -> bool`
1.7.0

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

This property is defined in RFC 6890.

#### `fn is_global(&self) -> bool`

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.

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

#### `fn is_unique_local(&self) -> bool`

Unstable (`ip` #27709)

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

Returns true if this is a unique local address (IPv6).

Unique local addresses are defined in RFC 4193 and have the form fc00::/7.

#### `fn is_unicast_link_local(&self) -> bool`

Unstable (`ip` #27709)

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

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

#### `fn is_unicast_site_local(&self) -> bool`

Unstable (`ip` #27709)

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

Returns true if this is a deprecated unicast site-local address (IPv6 fec0::/10).

#### `fn is_documentation(&self) -> bool`

Unstable (`ip` #27709)

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

Returns true if this is an address reserved for documentation This is defined to be 2001:db8::/32 in RFC 3849.

#### `fn is_unicast_global(&self) -> bool`

Unstable (`ip` #27709)

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

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

#### `fn multicast_scope(&self) -> Option<Ipv6MulticastScope>`

Unstable (`ip` #27709)

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

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

#### `fn is_multicast(&self) -> bool`
1.7.0

Returns true if this is a multicast address.

Multicast addresses have the form ff00::/8, and this property is defined by RFC 3956.

#### `fn to_ipv4(&self) -> Option<Ipv4Addr>`

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

#### `fn octets(&self) -> [u8; 16]`

Unstable (`ipv6_to_octets` #32313)

: needs some testing

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
