It is possible that an interface has both IPv4 and IPv6 addresses, primarily when using SLAAC with OpenStack Neutron. When this is the case, it is very likely that the first fixed IP would be a SLAAC assigned port and the second IP is the IPv4 address. In an environment where you are looking to boot via IPv4, no DHCPv6 infrastructure exists as IPv6 connectivity is provided via SLAAC, you would not be able to use this network to boot off of. This patch instead grabs all the fixed IP addresses, then inserts the options that match the IP versions which are attached to the interface, potentially resulting in both IPv4 and IPv6 options being included (though the IPv6 ones would be largely omitted). In environments where only IPv4 or IPv6 is in use on the port, it will still only insert the options for those specific IP versions.

Overview
Ironic consists of an API and plug-ins for managing and provisioning physical machines in a security-aware and fault-tolerant manner. It can be used with nova as a hypervisor driver, or standalone service using bifrost. By default, it will use PXE and IPMI to interact with bare metal machines. Ironic also supports vendor-specific plug-ins which may implement additional functionality.
