dhcp

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 dhcpv4 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
• dhcpv6 server
• dhcpv6 packet crafting
• TODO dhcpv4 client
• TODO dhcpv4 server
• TODO dhcpv4 packet crafting
