Skype, by default, will tell you when there is a patch available. Also if you don't patch you are not in a worse position than you will be when your ISP starts to hand you ambigious addresses that are not identified as such. What we do in is a way for the customers to request non-ambigious addresses in response to DHCP/PPP etc. requests along side this allocation and for the return address to be properly annotated. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@xxxxxxx _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
