Struct ipnet::Ipv6Net

pub struct Ipv6Net { /* fields omitted */ }

An IPv6 network address.

See IpNet for a type encompassing both IPv4 and IPv6 network addresses.

Textual representation

Ipv6Net provides a FromStr implementation. This is represented using the FromStr implementation for Ipv6Addr followed by a / character and the prefix length in decimal. See IETF RFC 4632 for the CIDR notation.

Examples

use std::net::Ipv6Addr;
use std::str::FromStr;
use ipnet::Ipv6Net;

let net_v6 = Ipv6Net::from_str("fd00::/32").unwrap();
assert_eq!("fd00::".parse(), Ok(net_v6.network()));

Methods

impl Ipv6Net

fn new(ip: Ipv6Addr, prefix_len: u8) -> Ipv6Net

Creates a new IPv4 network address from an Ipv4Addr and prefix length.

• If prefix_len is greater than 128 it will be clamped to 128.

Examples

let net = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24);

fn prefix_len(&self) -> u8

Returns the prefix length.

fn netmask(&self) -> Ipv6Addr

Returns the network mask.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00::/24").unwrap().netmask(),
    Ipv6Addr::from_str("ffff:ff00::").unwrap()
);

fn hostmask(&self) -> Ipv6Addr

Returns the host mask.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00::/24").unwrap().hostmask(),
    Ipv6Addr::from_str("::ff:ffff:ffff:ffff:ffff:ffff:ffff").unwrap()
);

fn network(&self) -> Ipv6Addr

Returns the network address.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00:1234:5678::/24").unwrap().network(),
    Ipv6Addr::from_str("fd00:1200::").unwrap()
);

fn broadcast(&self) -> Ipv6Addr

Returns the broadcast address.

• Technically there is no such thing as a broadcast address for IPv6. This can be thought of as an end() method.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00:1234:5678::/24").unwrap().broadcast(),
    Ipv6Addr::from_str("fd00:12ff:ffff:ffff:ffff:ffff:ffff:ffff").unwrap()
);

fn trunc(&self) -> Ipv6Net

Return a copy of the network with the address truncated to the prefix length.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00::1:2:3:4/16").unwrap().trunc(),
    Ipv6Net::from_str("fd00::/16").unwrap()
);

fn supernet(&self) -> Option<Ipv6Net>

Returns the Ipv6Net that contains this one.

Examples

assert_eq!(
    Ipv6Net::from_str("fd00:ff00::/24").unwrap()
        .supernet().unwrap().trunc(),
    Ipv6Net::from_str("fd00:fe00::/23").unwrap()
);

fn is_sibling(&self, other: &Ipv6Net) -> bool

Returns true if this network and the given network are children of the same supernet.

Examples

let net1 = Ipv6Net::from_str("fd00::/18").unwrap();
let net2 = Ipv6Net::from_str("fd00:4000::/18").unwrap();
let net3 = Ipv6Net::from_str("fd00:8000::/18").unwrap();
assert!(net1.is_sibling(&net2));
assert!(!net2.is_sibling(&net3));

fn hosts(&self) -> IpAddrIter<Ipv6Addr>

Return an Iterator over the host addresses in this network.

Examples

let net = Ipv6Net::from_str("fd00::/126").unwrap();
assert_eq!(net.hosts().collect::<Vec<Ipv6Addr>>(), vec![
    Ipv6Addr::from_str("fd00::").unwrap(),
    Ipv6Addr::from_str("fd00::1").unwrap(),
    Ipv6Addr::from_str("fd00::2").unwrap(),
    Ipv6Addr::from_str("fd00::3").unwrap(),
]);

fn subnets(&self, new_prefix_len: u8) -> IpNetIter<Ipv6Net>

Returns an Iterator over the subnets of this network with the given prefix length.

• If new_prefix_len is greater than 128 it will be clamped to 128.

assert_eq!(net.subnets(18).collect::<Vec<Ipv6Net>>(), vec![
    Ipv6Net::from_str("fd00::/18").unwrap(),
    Ipv6Net::from_str("fd00:4000::/18").unwrap(),

    Ipv6Net::from_str("fd00:c000::/18").unwrap(),
]);

let net = Ipv6Net::from_str("fd00::/126").unwrap();
assert_eq!(net.subnets(128).collect::<Vec<Ipv6Net>>(), vec![
    Ipv6Net::from_str("fd00::/128").unwrap(),
    Ipv6Net::from_str("fd00::1/128").unwrap(),
    Ipv6Net::from_str("fd00::2/128").unwrap(),
    Ipv6Net::from_str("fd00::3/128").unwrap(),
]);

let net = Ipv6Net::from_str("fd00::/16").unwrap();
