Maybe you should pressure your corporation (not "coroporation"- another reason you should be using an up-to-date browser- spell check is a good thing) into updating the policy to allow at least IE7 or IE8 or some other browser, like Firefox or Chrome. I've thought about it, and I don't want to support IE6 users visiting this site. So, either don't visit my site with IE6 or use a different browser. After all, I didn't force you here. You came here on your own. You're more than welcome to leave. @you’re awesome

Heyah, very nice article, though i think there is a mistake in the pixel representation of IPv4
256 * 256 = 65536 = 2^16 pixels in your square
IPv4 address space = 2^32 addresses
so each pixel should be 2^16 addresses to get 2^16 * 2^16 = 2^32 addresses

Does the solar system representation then count?

Schaefer Wed, 11 Mar 2009 13:55:40 +0000 http://pthree.org/?p=973#comment-109846 When I tried to get redundant routing from two separate ISPs, I learned that no public ISP routes less than a /24 and many don't route less than a /22. I don't understand the advantage to IPv6 until there is routing for /48 - and I haven't seen that discussed. What's the point to having an address if no one can discover how to get there?

IPv4 is 2^32, dropping 2^16 (2^8 * 2^8 image) leaves 2^16 IP's per pixel, or a /16, 64k IP's per pixel. Also my personal way of describing v6 is: * Each ISP gets 4-billion subnets (a /32), there's potentially 4 billion of these * Each user is assigned either 256 (a /56) or 64k (a /48) subnets, 64k large allocations or 16M smaller ones * Each subnet is four billion times the size of the entire IPv4 internet Your comment about the IPv4 image is wrong.

IPv4 is 2^32, dropping 2^16 (2^8 * 2^8 image) leaves 2^16 IP’s per pixel, or a /16, 64k IP’s per pixel.

Also my personal way of describing v6 is:
* Each ISP gets 4-billion subnets (a /32), there’s potentially 4 billion of these
* Each user is assigned either 256 (a /56) or 64k (a /48) subnets, 64k large allocations or 16M smaller ones
* Each subnet is four billion times the size of the entire IPv4 internet

If there are exactly 6.5 billion people on the planet, and each person lived in their own house, and each of house had 6.5 billion light switches (I think we've grossly overdone an even remotely accurate representation, no?), we would still have left over 340,282,366,920,938,463,421,124,607,431,768,211,456 addresses. Yeah- we're barely scratching the surface with that one. You might want to tell your professor to find a better model. :) It’s a bit larger than that.

IPng anyone? I’d like a larger address space as much as the next guy, but using phrases like:
