Isn't it possible for the DHCPv6 server to return IPv4 addresses as per RFC 2373, section 2.5.4 (IPv6 Addresses with Embedded IPv4 Addresses), in particular: A second type of IPv6 address which holds an embedded IPv4 address is also defined. This address is used to represent the addresses of IPv4-only nodes (those that *do not* support IPv6) as IPv6 addresses. This type of address is termed an "IPv4-mapped IPv6 address" and has the format: | 80 bits | 16 | 32 bits | +--------------------------------------+--------------------------+ |0000..............................0000|FFFF| IPv4 address | +--------------------------------------+----+---------------------+ - Bernie -----Original Message----- From: Ralph Droms [mailto:rdroms@cisco.com] Sent: Monday, February 24, 2003 12:43 PM To: dhcwg@ietf.org; ipng@sunroof.eng.sun.com; namedroppers@ops.ietf.org Subject: Re: [dhcwg] Re: WG last call on draft-ietf-dhc-dhcpv6-opt-dnsconfig-02.txt Summary of discussion during WG last call on draft-ietf-dhc-dhcpv6-opt-dnsconfig-02.txt Pekka Savola, Tony Lindstrom, Bernie Volz and Peter Koch all responded with editorial suggestions. These suggestions have been incorporated into the draft and will appear in next published rev. Peter Koch and Rob Austein commented on the "Security Considerations"; specifically, whether DNSSEC can prevent problems caused by a search list supplied as part of an attack by a DHCP server. Based on Rob's argument (and assuming I understood Rob correctly) that DNSSEC can guarantee that a host can trust the replies it receives, but DNSSEC can't guarantee that the host has asked the right question based on its search list, I'm inclined to leave the text in question unchanged. Alain Durand raised the issue of supplying both IPv4 and IPv6 addresses for DNS resolvers in the DNS server option. I judged the rough consensus in the responses to be that restricting the DNS server option to return only IPv6 addresses is acceptable. - Ralph _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
