Re: [dhcwg] PKIX WG new I-D draft: DHCP section review

You could choose either IP addresses or FQDNs for the option payload.   
But, you'll still have to define both DHCPv4 and DHCPv6 versions of  
the option.

You might want to look at http://www.ietf.org/internet-drafts/draft-ietf-dhc-option-guidelines-03.txt
