If you have IPv6 enabled (in config/general.h), then iPXE will attempt 
to autoconfigure via both IPv4 and IPv6, and will use whatever 
autoconfiguration is offered (with no explicit priority given to either 
protocol).

IPv6 autoconfiguration uses router advertisements (which is sufficient 
to pick up an IPv6 address, DNS server address, and DNS search list). 
If the router advertisement specifies that the network uses stateless or 
stateful DHCPv6, then iPXE will use that to obtain further configuration 
(including possible a bootfile URL).

If you want to explicitly boot from IPv6 on a dual IPv4/IPv6 network, 
then you can use e.g.

   ifconf -c ipv6
   chain ${filename}

to avoid picking up the network's IPv4 configuration.
