  1. static addressing by No-op · · Score: 5

    well, one thing with IPv6 (kind of like IPX in this respect) is that the last 48 bits of your address are your MAC address. while this is ethernet (and compatible) addressing specific, that's most everything these days. so it's not even a matter of static or dynamic anymore, as everything just *IS* what it is, and that's about it. I don't know if you remember the IPX days, or even experienced them, but there wasn't much of an issue with addressing with it (at least in the same respect as we have with IP now.) I look forward to IP addressing being less of an issue.

    That being said, routing protocols will need to be furthered, and some of the new routing protocols as well as the IPv6 versions of old standbys (like BGP, OSPF, etc) are pretty slick. think about the amount of route summarization you'd need to do for BGP so you don't kill yourself! we're talking massive exponentional expansions in potential routes. ouch. I think that's why most of the IPv6 space is going to be kept close together to save us all the hassle of watching our older equipment die under the load. thinking of all those little ISP's loading up IPv6 BGP on a cisco 3640 or something equivalent just makes me want to cry :)

    Here's a good link on the routing issues moving to IPv6: http://www.t17.ds.pwr.wroc.pl/~misiek/ipv6/!Docume ntation/ip6routing.html

  2. Everyone can have huge networks by Que_Ball · · Score: 5

    They are basically saying that in IPv6 everyone will be given a /48 which means that as you connect to your ISP it will automatically give you a range of IP addresses large enough for you to have 2^16 or 65536 different subnets. Because IPv6 is a 64bit network with 64bit host system that means each subnet can have practically an unlimited number of devices in it. You can basically give every piece of dust floating around in your house an IP address and each room could be on it's own subnet!

    And still as they state, they can easily give up to 178 billion of these /48 network numbers away until address assignment starts to become an issue again which still leaves 85% of the address space unused.

    Now the real trick as the article alludes to but doesn't really address is the complexity of handling the routing for multihomed sites. Someone still has to figure out how to make multihomed routing easy, fast, and efficient.

    a link to an informative article.. no spelling errors.. no long rant about something no one is interested it..

    this can't be slashdot.. if it is.. i feel kind of betrayed..
