Implementations

impl IpNetwork

pub fn new(ip: IpAddr, prefix: u8) -> Result<IpNetwork, IpNetworkError>

Constructs a new IpNetwork from a given IpAddr and a prefix denoting the network size. If the prefix is larger than 32 (for IPv4) or 128 (for IPv6), this will raise an IpNetworkError::InvalidPrefix error. Support for IPv6 is not complete yet.

pub fn with_netmask( netaddr: IpAddr, netmask: IpAddr, ) -> Result<IpNetwork, IpNetworkError>

Constructs a new IpNetwork from a network address and a network mask.

If the netmask is not valid this will return an IpNetworkError::InvalidPrefix.

pub fn ip(&self) -> IpAddr

Returns the IP part of a given IpNetwork

pub fn prefix(&self) -> u8

Returns the prefix of the given IpNetwork

Example

use ipnetwork::IpNetwork;

assert_eq!(IpNetwork::V4("10.9.0.1".parse().unwrap()).prefix(), 32u8);
assert_eq!(IpNetwork::V4("10.9.0.32/16".parse().unwrap()).prefix(), 16u8);

assert_eq!(IpNetwork::V6("ff01::0".parse().unwrap()).prefix(), 128u8);
assert_eq!(IpNetwork::V6("ff01::0/32".parse().unwrap()).prefix(), 32u8);

pub fn network(&self) -> IpAddr

Returns the address of the network denoted by this IpNetwork. This means the lowest possible IP address inside of the network.

Examples

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

let net: IpNetwork = "10.1.9.32/16".parse().unwrap();
assert_eq!(net.network(), Ipv4Addr::new(10, 1, 0, 0));
let net: IpNetwork = "2001:db8::/96".parse().unwrap();
assert_eq!(net.network(), Ipv6Addr::new(0x2001, 0xdb8, 0, 0, 0, 0, 0, 0));

pub fn broadcast(&self) -> IpAddr

Returns the broadcasting address of this IpNetwork. This means the highest possible IP address inside of the network.

Examples

use std::net::Ipv4Addr;
use ipnetwork::{IpNetwork, Ipv4Network};

let net: Ipv4Network = "10.9.0.32/16".parse().unwrap();
assert_eq!(net.broadcast(), Ipv4Addr::new(10, 9, 255, 255));

pub fn mask(&self) -> IpAddr

Returns the mask for this IpNetwork. That means the prefix most significant bits will be 1 and the rest 0

Example

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

let v4_net: IpNetwork = "10.9.0.1".parse().unwrap();
assert_eq!(v4_net.mask(), Ipv4Addr::new(255, 255, 255, 255));
let v4_net: IpNetwork = "10.9.0.32/16".parse().unwrap();
assert_eq!(v4_net.mask(), Ipv4Addr::new(255, 255, 0, 0));

let v6_net: IpNetwork = "ff01::0".parse().unwrap();
assert_eq!(v6_net.mask(), Ipv6Addr::new(0xffff, 0xffff, 0xffff, 0xffff, 0xffff, 0xffff, 0xffff, 0xffff));
let v6_net: IpNetwork = "ff01::0/32".parse().unwrap();
assert_eq!(v6_net.mask(), Ipv6Addr::new(0xffff, 0xffff, 0, 0, 0, 0, 0, 0));

pub fn is_ipv4(&self) -> bool

Returns true if the IP in this IpNetwork is a valid IPv4 address, false if it’s a valid IPv6 address.

Example

 use ipnetwork::IpNetwork;

 let v4: IpNetwork = IpNetwork::V4("10.9.0.32/16".parse().unwrap());
 assert_eq!(v4.is_ipv4(), true);
 assert_eq!(v4.is_ipv6(), false);

pub fn is_ipv6(&self) -> bool

Returns true if the IP in this IpNetwork is a valid IPv6 address, false if it’s a valid IPv4 address.

Example

 use ipnetwork::IpNetwork;

 let v6: IpNetwork = IpNetwork::V6("ff01::0/32".parse().unwrap());
 assert_eq!(v6.is_ipv6(), true);
 assert_eq!(v6.is_ipv4(), false);

pub fn contains(&self, ip: IpAddr) -> bool

Checks if a given IpAddr is in this IpNetwork

Examples

use std::net::IpAddr;
use ipnetwork::IpNetwork;

let net: IpNetwork = "127.0.0.0/24".parse().unwrap();
let ip1: IpAddr = "127.0.0.1".parse().unwrap();
let ip2: IpAddr = "172.0.0.1".parse().unwrap();
let ip4: IpAddr = "::1".parse().unwrap();
assert!(net.contains(ip1));
assert!(!net.contains(ip2));
assert!(!net.contains(ip4));

pub fn size(&self) -> NetworkSize

Returns the number of possible host addresses in this IpAddr

Examples

use ipnetwork::{IpNetwork, NetworkSize};


let net: IpNetwork = "127.0.0.0/24".parse().unwrap();
assert_eq!(net.size(), NetworkSize::V4(256))

pub fn iter(&self) -> IpNetworkIterator

Returns an iterator over the addresses contained in the network.

This lists all the addresses in the network range, in ascending order.
