It also suffers from serious performance and security problems (one DNS request may cause multiple requests to "unfold" a prefix, and compromising a DNS node may also compromise other nodes because prefixes will be propagated), not to mention other minor problems (deploying might not be easier considering the configuration) See also http://www.faqs.org/rfcs/rfc3364.html " Resolving a chain of A6 RRs involves resolving a series of what are almost independent queries, but not quite. Each of these sub-queries takes some non-zero amount of time, unless the answer happens to be in the resolver's local cache already. " How many times did we have problems with slow/unreachable DNS servers ? Having multiple DNS involved will dramatically increase this risk. A6 are looking pretty nice, but are they the perfect solution considering the need for reliability/performances/security? --------------------------------------------------------------------- The IPv6 Users Mailing List Unsubscribe by sending "unsubscribe users" to [EMAIL PROTECTED]
