Blog Examples Going IPv6 Next Year

I'm not a big fan of New Year's resolutions (they always seem like a convenient way to procrastinate), but I have one for next year. Beginning January 1, 2011, I'm going to write blog articles using only IPv6 addressing in labs, where practical.
Since starting the blog nearly three years ago, I've tended to use IPv6 addressing in technical examples only when the topic being discussed dealt specifically with IPv6. No more. The last few remaining blocks of global IPv4 address space will be exhausted next year, and there is simply no excuse to avoid using IPv6 in documentation and examples.
Unfortunately, achieving parity with IPv4 for many features remains a struggle. There are still many cases where technologies simply don't work on IPv6 due to buggy or nonexistent implementation. IPv4 will still have to be used in these cases (for now), but I will make every effort to utilize IPv6 where possible.
For those of you still perhaps not quite comfortable with IPv6 yet, there are plenty of resources out there. This blog has an entire category dedicated to IPv6 articles, plus there's the IPv6 cheat sheet. There are a plethora of books on IPv6 and specific implementations available. I also suggest reading the core IPv6 RFC, RFC 2460 (it's not as scary as it sounds). Finally, the documentation from Cisco and other vendors should provide plenty of background information on specific platforms.

Good news Jeremy! (I've made our IPv6 prefix visible already, however it'll take time our IT dept to bring IPv6 resources online).
Btw, would you be so kind to shed some light on IPv6 SNMP things: how, for instance, I can monitor ipv6 bgp neighbor status and amount of prefixes received?

Right on Right on. IPV6 is coming, I've heard this for the last 15 years, well guess what it's going into production..so everyone has to get used to it!

Great idea, what better way to force me to understand IPv6. Let's watch my knowledge increase over the months (I hope any way).

Cool idea, but ipv4 addresses are still going to be around. Don't you think it would be beneficial to include examples for the users that will still be using ipv4?

Great!!, I hope to understand once and for all
