| ip 6 questions
Please forgive me, if this has been asked before. in ip 6 since every item has an ip address what happens to the routing protocols like BGP since no more subnetting are the routing tables gonna list every ip? or is there some hybrid protocol out there? i understand where at a minimum of 5-7 years before we start to implement it but i was just curious. |

IPv6 implementation is already underway.

Quite the opposite, there will be a lot less routes in the global routing table due to much better aggregation of routes. Rather then a large ISP having a lot of blocks they'll have 1 - 2 large blocks of v6 addresses. Lots of information on this out on the net and a lot of people already using v6 day to day. IMO most residential US ISP's won't start pushing v6 out to the users until either they can't get v4 addresses or when some sites become v6 only. |

A couple other posters answered the basic questions, but I'll put my couple cents in.
BGP is still going to be required for the global Internet, because that's how everyone is going to know about everyone else's routes, AS paths, etc. As was highlighted though, you won't be getting thousands of little routes for each AS. The IPv6 space is large enough that there isn't the same need to allocate microblocks like IPv4's CIDR and such. I expect most AS announcements to be one route, maybe two.
IPv6 implementation is already underway, and has been for the better part of a decade. WinXP, Vista, MacOS X, *nix, all have appropriately functional IPv6 stacks in them. Also, most modern core network hardware has IPv6 capability already. Some older hardware doesn't have IPv6 in ASICs like IPv4 does, but that is more rare than not at this stage.
However, IPv6 is severely lacking in residential gateway hardware. From the way I understand IPv6, those devices will probably more or less act like bridges and stateful firewalls. NAT will be eliminated, but something will need to watch the gates for unauthorized traffic, per se. |

I know its being implemented now but i figure at least 5 years before its the de facto standard. |

|  Hey, no problem with the help. A lot of us look forward to the new technology and some of the advances and features it promises. I am looking forward to having the ability to eliminate NAT, increasing multicast use and simplifying video and voice applications.
Good luck with the CCNA!
