Hot on the heels of our recent DSL upgrade experience comes this revelation about the state of consumer-grade network gear — DSL & cable modems, routers, etc. — As the world “runs out of” IPv4 (Internet) addresses, the stuff that Cisco/Linksys, Netgear and others would sell us (or our ISPs would provide us) are just not ready for IP version 6… to-wit, from this NetworkWorld article:
When it comes to IPv6 support, consumer home networking gear lags far behind other devices, like enterprise equipment and PC operating systems. Most devices certified as IPv6-compliant by the IPv6 Forum are full of implementation bugs, experts say…
Given that “the givens” for home-based or SOHO network gear are stateful packet inspection, firewall, and NAT (network address translation), it’d be nice to presume that the major manufacturers will start getting this right, sooner rather than later. I can’t wait ’til we all get to try that upgrade!…

And I hope that the two articles about upgrading DSL are helpful… Every time I’ve gone Googling for help & guidance on this sort of topic, all I’ve found are fragmentary, and frequently wrong or misleading, advice. I wrote these articles, “the whole story”, as an attempt to help someone else from beginning to end with a similar problem. Often, the devil’s in the details, and the context, not just “type this command, see this result.”
Thanks for the feedback! It helps to know someone’s reading and cares enough to comment… This is a WordPress blog/site, and I’m very pleased with the features and support from WordPress.com — thanks again!
