Re: cost of dual-stack vs cost of v6-only [Re: IPv6 on SOHO routers?]

There are already things like http://ipv6.google.com/, though content which is _only_ available over IPv6 is probably more likely to stimulate demand. But there's no $$ benefit for being either the chicken or the egg. The carriers (many still with oversized debt loads) don't see any advantage for deployment in a general sense. But they'll likely have an easier time than access providers. it's a 'no thanks, but I need more address space' for many of the access providers, given the orders of magnitude of ports, customers, customer care, billing systems and so on that may have to be updated to handle yet another layer in their networks. And content providers without an audience are just toying around. Maybe they'll have the easiest time. hard to say. It's almost like the volunteer line, where everyone else in line has to step back so that someone gets stuck being first doing the dirty work. Same for the end user. They don't care how a microwave oven works, they simply toss in a bag, press the popcorn button and expect results. regards, andy

This is the first time I've heard this posited -- I had a hard believing that, but he claims it with some authority. Anyone hear anything like this? My own opinion is that we'll see dual-stack for at least a decade or two to come. ISP's are very good at one thing, driving out unnecessary cost. Running dual stack increases cost. While I'm not sure about the 5 year part, I'm sure ISP's will move to disable IPv4 support as soon as the market will let them as a cost saving measure. Runing for "decades" dual stacked does not make a lot of economic sense for all involved. labels in the core, for a long while. This transition will be about as smooth as the US moving to the metric system. (e.g. everyone buys soda in two liter bottles, wine in 750ml bottles, but can't mentally buy liters of gasolineor 1.1826 liters of beer, aka 'forty'). Same could be said for the Auto Industry. Thank [some dead mathematician] that 3/4" lug nuts are also 19mm or we'd really be screwed :-) No flag day here (I would pay serious money to see that happen though, it would be a total riot from the get go). There is some interesting movement in the US in particular to put up 'enough' v6 window dressing to be compliant with US gov't contracts and so on which will match up with the OMB [unfunded] mandate to be IPv6 compatible by this june. As for the SOHO, not sure if anything other the next chip revision and firmware are needed. Besides, will they be NAT boxen with a dozen application layer gateway helpers like today? Or will they be actual firewalls. Hard to say which is more difficult or code complex. With the pace of silicon replacement in SOHO product lines, the next silicon spin could do the either stack or both for the same cost. best regards, andy
Re: Network graphics tools
Howard C. Berkowitz wrote: Much of the enterprise market seems wedded to Visio as their network graphics tool, which locks them into Windows. Personally, I hate both little pictures of equipment and Cisco hockey-puck icons; I much prefer things like rectangles saying "7507 STL-1" or "M160 NYC-3". Assuming you use *NIX platforms (including BSD under Mac OS X), what are your preferred tools for network drawings, both for internal and external use? I'd hate to be driven to Windows only because I need Visio. http://www.nethack.net/software/netmapr/ is an alternative as well. I personally use Dia, and it seems fine in both OS types, and exports various types of files that [OOo/MS-office] can deal with easily. You can download shapes for a variety of presenters/office/visio/etc from the cisco website (as well as others). Cheers, andy
