IPv6 DNS Autoconfiguration
Hi, DNSOP members! :-) Beforehand, I'd like to summarize my talk for today's discussion about DNS Discovery and Autoconfiguration. I'll present IPv6 DNS autoconfiguration today afternoon. IPv6 DNS autoconfiguration consists of two functions; a) RA-based DNS Discovery and b) Host DNS Name Auto-Registration. Through RA DNS option, IPv6 host can find out DNS information, such as Recursive DNS Servers' addresses and DNS Zone Suffix. It is very simple and necessary mechanism, I think. With the announced DNS zone suffix, IPv6 host can generate its host DNS name based on its preferred user-ID. Also, it can register its DNS name and IPv6 address with the announced DNS server, through DNS dynamic update. The registration is performed by the IPv6 host, not another Registrar. In my scheme, any unidentified host can register its DNS information in advertised DNS server. To minimize the damage of DNS dynamic update, I define a new flag, AR (Auto-Registration), in Header section of DNS dynamic update message. This bit indicates that any host can add its AAAA/PTR resource records in DNS server and modifiy or delete only its resource records, not others' resource records. Therefore, a little extension to DNS Dynamic Update is necessary. You can find my presentation material in the following links; http://www.adhoc.6ants.net/~paul/data/ietf57-dnsop-ipv6-ra-dns-autoconf-00.pdf http://www.adhoc.6ants.net/~paul/data/ietf57-dnsop-ipv6-ra-dns-autoconf-00.ppt I would like to know if DNS autoconfiguration should consider both DNS discovery and Host DNS name auto-registration or not, namely separate documents. In today's talks, I hope, some drafts about DNS autoconfiguration will be accepted as working items. Thanks. /Jaehoon (Paul) __________________________________ Do you Yahoo!? SBC Yahoo!
