An IPv6 address may be shortened by leaving off the leading zeros in the address, but this can only be done once in the address.
An example would be the address of 12AB:0000:0000:CD30:0000:0000:0000:0000/64 could be shortened to 12AB::CD30:0000:0000:0000:0000/64 or 12AB:0000:0000:CD30::/64 Check out RFC 2373 for more info on IPv6 ----Original Message Follows---- From: "Priscilla Oppenheimer" Reply-To: "Priscilla Oppenheimer" To: [EMAIL PROTECTED] Subject: Re: Since you are in a teaching mode...

IPv6 stateless autoconfiguration is similar to IPX addressing, although your last statement is sort of backwards. No server is required in IPv6. The client can listen to Router Advertisements that provide a prefix. (A host can also force an immediate Router Advertisement by transmitting a Router Solicitation message to the all-routers multicast address.) With IPX, a client broadcasts a Find Network Number. A server or router must respond. >My greatest concern about IPv6 (and this is probably due to my ignorance on >the subject) is the apperent reliance on name resolution.

There are shorthand ways of specifying IPv6 addresses I think. Maybe someone else knows for sure.
