The hope is the v6 DFZ will not grow nearly as fast because of far less fragmentation.

But who knows?

Also, even today TCAM ain’t cheap. Let’s hope it those numbers are not “nothing”.

These numbers are nothing. Wait till IPv6 really start taking off.

Subject: Re: Weekly Routing Table Report

A very long time ago, I commented on this report hitting 250,000 prefixes. It was a Big F*#@$&! Deal at the time. A 
quarter million prefixes in the DFZ? Wow….

Then I did it again at 500,000. People commented that I should have waited for 512,000 - especially since a popular 
piece of kit was expected to fall over at 512K prefixes. But I said I liked round numbers.

This time I waited for 768,000. (Everyone happy now?)

To say “the Internet grew more than anyone expected” is beyond cliché these days, but that does not make it any less 
true. The Internet has transformed from a curiosity into something my son[*] and a good portion of his entire 
generation cannot conceive of living without. A great many people on this list had a part in making all that happen.

Stop and think about that for a second. You had a part in literally changing the world.

It is a 3-day weekend in the US. A good time to pause for a few minutes and consider what all of us accomplished 
together. Pat yourselves on the back, raise a glass or whatever your personal traditions are, and bask in the glory 
of a job well done.

[*] The fact I can say “my son” is probably even more amazing. But that is a different story.
