[![Build Status](https://travis-ci.org/krisprice/ipnet.svg?branch=master)](https://travis-ci.org/krisprice/ipnet)
This module provides types and useful methods for working with IPv4 and IPv6 network addresses, commonly called IP prefixes. The new `IpNet`, `Ipv4Net`, and `Ipv6Net` types build on the existing `IpAddr`, `Ipv4Addr`, and `Ipv6Addr` types already provided in Rust's standard library and align to their design to stay consistent.
The module also provides the `IpSubnets`, `Ipv4Subnets`, and `Ipv6Subnets` types for iterating over the subnets contained in an IP address range. The `IpAddrRange`, `Ipv4AddrRange`, and `Ipv6AddrRange` types for iterating over IP addresses in a range. And traits that extend `Ipv4Addr` and `Ipv6Addr` with methods for addition, subtraction, bitwise-and, and bitwise-or operations that are missing in Rust's standard library.
The module only uses stable features so it is guaranteed to compile using the stable toolchain. Tests aim for thorough coverage and can be found in both the test modules and doctests. Please file an [issue on GitHub] if you have any problems, requests, or suggested improvements.
Read the [documentation] for the full details. And find it on [Crates.io].

[issue on GitHub]: https://github.com/krisprice/ipnet/issues
## Release 2.0 requirements
Release 2.0 requires Rust 1.26 or later. Release 1.0 used a custom emulated 128-bit integer type (`Emu128`) to fully support IPv6 addresses. This has been replaced with Rust's built-in 128-bit integer, which is now stable as of Rust 1.26. There are reports of issues using Rust's 128-bit integers on some targets (e.g. Emscripten). If you have issues on your chosen target, please continue to use the 1.0 release until that has been resolved.
## Examples
### Create a network address and print the hostmask and netmask
```rust
extern crate ipnet;
use std::net::{Ipv4Addr, Ipv6Addr};
use std::str::FromStr;
use ipnet::{IpNet, Ipv4Net, Ipv6Net};
fn main() {
// Create an Ipv4Net and Ipv6Net from their constructors.
let net4 = Ipv4Net::new(Ipv4Addr::new(10, 1, 1, 0), 24).unwrap();
let net6 = Ipv6Net::new(Ipv6Addr::new(0xfd, 0, 0, 0, 0, 0, 0, 0), 24).unwrap();
// They can also be created from string representations.
let net4 = Ipv4Net::from_str("10.1.1.0/24").unwrap();
let net6 = Ipv6Net::from_str("fd00::/24").unwrap();
// Or alternatively as follows.
let net4: Ipv4Net = "10.1.1.0/24".parse().unwrap();
let net6: Ipv6Net = "fd00::/24".parse().unwrap();
// IpNet can represent either an IPv4 or IPv6 network address.
let net = IpNet::from(net4);
// It can also be created from string representations.
let net = IpNet::from_str("10.1.1.0/24").unwrap();
let net: IpNet = "10.1.1.0/24".parse().unwrap();
// There are a number of methods that can be used. Read the
// documentation for the full details.
println!("{} hostmask = {}", net, net.hostmask());
println!("{} netmask = {}", net4, net4.netmask());
}
```
### Subdivide an existing IP network into smaller subnets
```rust
extern crate ipnet;
use ipnet::Ipv4Net;
fn main() {
let net: Ipv4Net = "192.168.0.0/23".parse().unwrap();
println!("\n/25 subnets in {}:", net);
// Note: `subnets()` returns a `Result`. If the given prefix length
// is less than the existing prefix length the `Result` will contain
// an error.
let subnets = net.subnets(25)
.expect("PrefixLenError: new prefix length cannot be shorter than existing");
// Output:
// subnet 0 = 192.168.0.0/25
// subnet 1 = 192.168.0.128/25
// subnet 2 = 192.168.1.0/25
// subnet 3 = 192.168.1.128/25
for (i, n) in subnets.enumerate() {
println!("\tsubnet {} = {}", i, n);
}
}
```
### Iterate over the valid subnets between two IPv4 addresses
```rust
extern crate ipnet;
use std::net::Ipv4Addr;
use ipnet::Ipv4Subnets;
fn main() {
let start = Ipv4Addr::new(10, 0, 0, 0);
let end = Ipv4Addr::new(10, 0, 0, 239);
println!("\n/0 or greater subnets between {} and {}:", start, end);
// Output all subnets starting with the largest that will fit. This
// will give us the smallest possible set of valid subnets.
//
// Output:
// subnet 0 = 10.0.0.0/25
// subnet 1 = 10.0.0.128/26
// subnet 2 = 10.0.0.192/27
// subnet 3 = 10.0.0.224/28
let subnets = Ipv4Subnets::new(start, end, 0);
for (i, n) in subnets.enumerate() {
println!("\tsubnet {} = {}", i, n);
}
println!("\n/26 or greater subnets between {} and {}:", start, end);
// Output all subnets with prefix lengths less than or equal to 26.
// This results in more subnets, but limits them to a maximum size.
//
// Output:
// subnet 0 = 10.0.0.0/26
// subnet 1 = 10.0.0.64/26
// subnet 2 = 10.0.0.128/26
// subnet 3 = 10.0.0.192/27
// subnet 4 = 10.0.0.224/28
let subnets = Ipv4Subnets::new(start, end, 26);
for (i, n) in subnets.enumerate() {
println!("\tsubnet {} = {}", i, n);
}
}
```
### Aggregate a list of IP prefixes
```rust
extern crate ipnet;
use ipnet::IpNet;
fn main() {}
// Example input list of overlapping and adjacent prefixes.
let strings = vec![
"10.0.0.0/24", "10.0.1.0/24", "10.0.1.1/24", "10.0.1.2/24",
"10.0.2.0/24",
"10.1.0.0/24", "10.1.1.0/24",
"192.168.0.0/24", "192.168.1.0/24", "192.168.2.0/24", "192.168.3.0/24",
"fd00::/32", "fd00:1::/32",
];
let nets: Vec<IpNet> = strings.iter().filter_map(|p| p.parse().ok()).collect();
println!("\nAggregated IP prefixes:");
// Output:
// 10.0.0.0/23
// 10.0.2.0/24
// 10.1.0.0/23
// 192.168.0.0/22
// fd00::/31
for n in IpNet::aggregate(&nets) {
println!("\t{}", n);
}
}
```
## Future
* Implementing `std::ops::{Add, Sub, BitAnd, BitOr}` for `Ipv4Addr` and `Ipv6Addr` would be useful as these are common operations on IP addresses. If done, the extension traits provided in this module would be removed and the major version incremented. Implementing these requires a change to the standard library. I've started a thread on this topic on the [Rust Internals](https://internals.rust-lang.org/t/pre-rfc-implementing-add-sub-bitand-bitor-for-ipaddr-ipv4addr-ipv6addr/) discussion board.
* The results of `hosts()` and potentially `subnets()` should be represented as a `Range` rather than the custom `IpAddrRange` and `IpSubnets` types provided in this module. This requires the target types to have `Add` and `Step` implemented for them. Implementing `Add` for `IpAddr`, `Ipv4Addr`, and `Ipv6Addr` requires a change to the standard library (see above). And `Step` is still unstable so exploring this will also wait until it has stablized.

# Releases
## Version 2.5.0
* Manually implement JsonSchema for IpNet, Ipv4Net, Ipv6Net #41 because default derived JsonSchema does not correspond to Serde representation #40
## Version 2.4.0
* Add 'schemars' feature for deriving JSON schema #31
* add convenience IpNet::new method #36
## Version 2.3.1 (2020-06-15)
* Merge Fix Error::description() deprecation warning #28.
## Version 2.3.0 (2020-03-15)
* Merge @imp's `Default` implementation. See #18. `Ipv4Net` and `Ipv6Net` now default to 0.0.0.0/0 and ::/0 respectively. `IpNet` defaults to the 0/0 `Ipv4Net`.
* Add `#[allow(arithmetic_overflow)]` for `Ipv4AddrRange::count()` and `Ipv6AddrRange::count()`. Since 1.43.0-nightly it gives a build error but this panic behavior is desired. In future it may be replaced with explicit use of `panic!`. See #21.
## Version 2.2.0 (2020-02-02)
* Implement `From<IpAddr>`, `From<Ipv4Addr>`, and `From<Ipv6Addr>` for `IpNet`, `Ipv4Net`, and `Ipv6Net` respectively.
## Version 2.1.0 (2019-11-08)
* Implement `FusedIterator` for `IpAddrRange`, `Ipv4AddrRange`, `Ipv6AddrRange`, `IpSubnets`, `Ipv4Subnets`, and `Ipv6Subnets`.
* Implement `DoubleEndedIterator` for `IpAddrRange`, `Ipv4AddrRange`, `Ipv6AddrRange`.
* Implement custom `count()`, `last()`, `max()`, `min()`, `nth()`, and `size_hint()` for `IpAddrRange`, `Ipv4AddrRange`, `Ipv6AddrRange`.
## Version 2.0.1 (2019-10-12)
* Fix bug where IpAddrRange never ends when start and end are both 0 #11
* Fix warning about missing 'dyn'
## Version 2.0.0 (2018-08-21)
* The `Emu128` module has been removed. This provided an emulated 128-bit integer for supporting IPv6 addresses. As of Rust 1.26 the built-in 128-bit integers have been marked stable and this library has been updated to use these instead of `Emu128`.
* The `with-serde` feature name shim has been removed. The `serde` feature should now be used using the bare `serde` feature name per the Rust API Guidelines.
* The `Deref` on `Ipv4Net` and `Ipv6Net` has been removed. This dereferenced to the `Ipv4Addr` and `Ipv6Addr` contained in the type. To use these methods call them directly on the contained IP address of interest, which may be accessed using the `addr()` or `network()` methods.
* In prior versions it was necessary to use the `Contains` trait to access the `contains()` methods. These are now inherited in public methods on the `IpNet`, `Ipv4Net`, and `Ipv6Net` types so are always available.
* The implementations of `IpAdd<u32>` and `IpSub<u32>` for IpAddr have been removed.
* The implementations of `IpAdd<u32>` and `IpSub<u32>` for `Ipv6Addr` have been removed.
## Version 1.2.1 (2018-06-06)
* Fix to resolve an issue with the optional serde support, where compact binary formats were not properly supported. See issue #10.
## Version 1.2.0 (2018-04-17)
* The previous release (1.1.0) introduced serde support using the feature name `with-serde`, but the Rust API Guidelines recommend using `serde` as the name of the feature. This release changes the feature name from `with-serde` to `serde`, but it is backwards compatible for those that already started using the `with-serde` feature name. The 1.1.0 release was yanked on crates.io to discourage further use of this feature name. See pull request #7.
## Version 1.1.0 (2018-04-13)
* Adds serde support. See pull request #6.

#![doc(html_root_url = "https://docs.rs/ipnet/2.5.0")]
//! Types for IPv4 and IPv6 network addresses.
//!
//! This module provides types and useful methods for working with IPv4
//! and IPv6 network addresses, commonly called IP prefixes. The new
//! [`IpNet`], [`Ipv4Net`], and [`Ipv6Net`] types build on the existing
//! [`IpAddr`], [`Ipv4Addr`], and [`Ipv6Addr`] types already provided in
//! Rust's standard library and align to their design to stay
//! consistent.
//!
//! The module also provides the [`IpSubnets`], [`Ipv4Subnets`], and
//! [`Ipv6Subnets`] types for iterating over the subnets contained in
//! an IP address range. The [`IpAddrRange`], [`Ipv4AddrRange`], and
//! [`Ipv6AddrRange`] types for iterating over IP addresses in a range.
//! And traits that extend `Ipv4Addr` and `Ipv6Addr` with methods for
//! addition, subtraction, bitwise-and, and bitwise-or operations that
//! are missing in Rust's standard library.
//!
//! The module only uses stable features so it is guaranteed to compile
//! using the stable toolchain.
//!
//! # Organization
//!
//! * [`IpNet`] represents an IP network address, either IPv4 or IPv6.
//! * [`Ipv4Net`] and [`Ipv6Net`] are respectively IPv4 and IPv6 network
//! addresses.
//! * [`IpSubnets`], [`Ipv4Subnets`], and [`Ipv6Subnets`] are iterators
//! that generate the smallest set of IP network addresses bound by an
//! IP address range and minimum prefix length. These can be created
//! using their constructors. They are also returned by the
//! [`subnets()`] methods and used within the [`aggregate()`] methods.
//! * [`IpAddrRange`], [`Ipv4AddrRange`], and [`Ipv6AddrRange`] are
//! iterators that generate IP addresses. These can be created using
//! their constructors. They are also returned by the [`hosts()`]
//! methods.
//! * The [`IpAdd`], [`IpSub`], [`IpBitAnd`], [`IpBitOr`] traits extend
//! the [`Ipv4Addr`] and [`Ipv6Addr`] types with methods to perform
//! these operations.

//! [`IpBitOr`]: trait.IpBitOr.html
//!
//! # Serde support
//!
//! This library comes with support for [serde](https://serde.rs) but
//! it's not enabled by default. Use the `serde` [feature] to enable.
//!
//! ```toml
//! [dependencies]
//! ipnet = { version = "2", features = ["serde"] }
//! ```
//!
//! For human readable formats (e.g. JSON) the `IpNet`, `Ipv4Net`, and
//! `Ipv6Net` types will serialize to their `Display` strings.
//!
//! For compact binary formats (e.g. Bincode) the `Ipv4Net` and
//! `Ipv6Net` types will serialize to a string of 5 and 17 bytes that
//! consist of the network address octects followed by the prefix
//! length. The `IpNet` type will serialize to an Enum with the V4 or V6
//! variant index prepending the above string of 5 or 17 bytes.
