DHCPv4 and DHCPv6 decoding/encoding library with client and server code, written in Go.

# How to get the library

The library is split into several parts:
* `dhcpv6`: implementation of DHCPv6 packet, client and server
* `dhcpv4`: implementation of DHCPv4 packet, client and server
* `netboot`: network booting wrappers on top of `dhcpv6` and `dhcpv4`
* `iana`: several IANA constants, and helpers used by `dhcpv6` and `dhcpv4`
* `rfc1035label`: simple implementation of RFC1035 labels, used by `dhcpv6` and
  `dhcpv4`
* `interfaces`, a thin layer of wrappers around network interfaces

You will probably only need `dhcpv6` and/or `dhcpv4` explicitly. The rest is
pulled in automatically if necessary.


So, to get `dhcpv6` and `dhpv4` just run:
```
go get -u github.com/insomniacslk/dhcp/dhcpv{4,6}
```


# Examples

The sections below will illustrate how to use the `dhcpv6` and `dhcpv4`
packages.

* [dhcpv6 client](examples/client6/)
* [dhcpv6 server](examples/server6/)
* [dhcpv6 packet crafting](examples/packetcrafting6)
* TODO dhcpv4 client
* TODO dhcpv4 server
* TODO dhcpv4 packet crafting
