RE: rack power question
Paul, Using a multi-stage filter system with the large partical filters in front and an ionizing stage to remove smaller but still large enough particals to cause dust. Clean room filters would be an overkill.

RE: Transition Planning for IPv6 as mandated by the US Govt
My understanding of the mandate is that they (the Department and Agencies) demonstrate passing IPv6 traffic on their backbone from one system out to their backbone and back to another system. A number of agencies, if I remember the number of about 30 have IPv6 allocations. IRS has demonstrated mandate compliance and several others are in line to also show mandate compliance. Both the Federal CIO Council and the Small CIO council are working with a number of their members to not only obtain compliance with the mandate but examine their processes to see how IPv6 can give them a better method of providing their services to each other and the public. John (ISDN) Lee From: [EMAIL PROTECTED] on behalf of Glen Kent Sent: Sat 3/15/2008 2:19 AM To: NANOG list Subject: Transition Planning for IPv6 as mandated by the US Govt Hi, I was just reading http://www.whitehouse.gov/omb/egov/b-1-information.html#IPV6, released some time back in 2005, and it seems that the US Govt. had set the target date of 30th June 2008 for all federal govt agencies to move their network backbones to IPv6. This deadline is almost here. Are we any close for this transition? I have another related question: Do all ISPs atleast support tunneling the IPv6 pkts to some end point? For example, is there a way for an IPv6 enthusiast to send his IPv6 packet from his laptop to a remote IPv6 server in the current circumstances if his ISP does not actively support native IPv6? Cheers, Glen
RE: IPv6 on SOHO routers?
If history is any guide the last Cisco boxes I worked on supported various flavors of SDLC and pre-SNA IBM comm, DECnet and DECnet LAT, IPX, Burroughs, poll select and the only protocol they do not still support is CorvisNet on twisted pair. Some of these protocols have not seen the light of day since when? What is a Good CCIE test without arcane SDLC, HDLC and DECnet protocol questions. Most SOHO routers use standard or proprietary silicon to do the IP stack or IP route assist and when the silicon is available for dual stack in quantity 10,000 units or more at a reasonable price the SOHO routers will support both. IMHO before Linksys was owned by Cisco, I liked Netgear because there code was from Bay networks and had better routing. Finally, when I bought the expensive $ 150.00 routers with integral VPN support that was neat. What I would like to see today is SOHO routers that do not interfere with 6 over 4 transport since my ISP does not offer home DSL termination of v6. Taking the silicon in a SOHO and adding 5 to 10 $ US in cost for v6 and multiple that by 5 to get a retail price of those features. Then offset that with the decrease in silicon size when you add both together with smaller size lines and transistors on the chips, I would project SOHO prices of 250 - 350 $ US to start with for v4 v6 and dropping from there.

Slightly off-topic, but tangentially related that I'll dare to ask. I'm attending an Emerging Communications course where the instructor stated that there are SOHO routers that natively support IPv6, pointing to Asia specifically. Do Linksys, D-Link, Netgear, etc. have such software for the Asian markets? Furthermore, he stated that networking equipment companies like Cisco will be moving away from IPv4 in 5 years or so. 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. Frank

Jeanette Symons (1962-2008) a commerical Internet Pioneer
It was with great sadness that I read about the un-timely death of my friend and colleague Jeanette in a plane crash in Maine. Jeanette died flying, which was one of the activities she loved to do. I meet her before she started flying and when she moved back to California she took up flying. We would be talking on the phone and she would say that it was VFR and she needed to go. VFR - Visual Flight Rules for flying without instruments which was all she was rated for at the time. I meet Jeanette at Hayes Microcomputer Products where we were working on a project together. People would think that we were brother and sister since we both had curly back hair and looked alike. When she wanted to move back to California, which she missed, I introduced her to Rob Ryan the head of Haye's West coast operations. When she was in Georgia we would eat Chinese, made by my wife, at my place. When we were in California we would eat Sushi at several of her favorite places in Western San Francisco and Oakland. Jeanette, Rob, Jay Duncanson and Steve Speckenbach left Hayes to start Ascend Communications and developed the TNT central site dial up modem, ISDN and Ethernet switch that handled most of the dial up Internet traffic for years. Ascend was purchased by Lucent and she and Mori started Zhone Technologies. Her new venture was started because her children wanted to blog with their friends and she was worried about them being on line. Jeanette will be missed. John Lee
