Buzz Out Loud 656: Rumor-palooza

From Google buying Bebo to Earthlink buying AOL to ARM processors in Google Android devices, it's rumor central today.

Sometimes there's just no news. And sometimes there's just rumors of news. Today is an example of the latter. Half the stories today are rumors of somebody coming out with some products or somebody buying somebody else. Plus we critique my resume.

Location-based ad
Hey Buzz crew,

Every time you guys (or anyone) talk about location-based ads on our phones, Starbucks is always brought up as an example. You might want to come up with something different. There is always a Starbucks across the street or on the next corner. You don't need any location detector for that.

Love the show!

Sprint Unlimited--not that unlimited
Hey Buzz team, short-time listener first-time e-mailer.

Just wanted to give you a heads up. From what I've been reading the Sprint unlimited plan does not cover data on smartphones and BlackBerrys. You'll still need to hand over an arm or leg to get unlimited data plans.

Cable update
Hello again,

FLAG telecom (the company in charge of those sea cables) released a bulletin yesterday with updates regarding the status of the server. They can be found on the official site. Some of the main points:

Cut # 1: FLAG Europe Asia Cable cut between Alexandria (Egypt) and Palermo (Italy)

The ship loaded with spares has reached the fault location and has initiated the repair work; the repair work is estimated to be completed within 6-7 days. The Mediterranean network will be fully resilient with the addition of FLAG Mediterranean Cable current under implementation. The cable cut was reported at 0800 GMT on January 30th 2008 around 8.3 Km away from Alexandria cable landing station between Egypt - Italy segment.

Cut # 2: FALCON Cable cut between Dubai (UAE) and Al Seeb(Oman)

The ship loaded with spares, marine experts, and optical engineers have reached the site yesterday. The crew has recovered the one end of the cable and cable joining work is in progress. The repair team has observed steady progress and the repair work are expected to be completed in next 3-4 days. The weather conditions are not favorable but the crew is continuing with the repair process. The cable cut was reported at 0559 GMT on February 1st 2008 around 56 Km from Dubai, UAE on segment between UAE and Oman.

Best regards...

How IPv6 will work
OK Buzz-kids...

Having heard two BOL podcasts where confused information about IPv6 was discussed, I'll try to present a simple, straight-forward, explanation of how IPv6 is supposed to work. Since I work in the industry, I have some insights into it.

IPv6 addresses are four times the length of IPv4 addresses, so that's 128 bits instead of 32. With that long of an address, the intent is that an ISP will give out an "IPv6 Prefix" to each customer instead of simply an address. So, the way it will work is that your IPv6 router will use "DHCPv6 Prefix Delegation" to acquire an IPv6 Prefix from your ISP. Your router will then use DHCPv6 (the IPv6 version of DHCP) to hand out addresses to each of the devices in your house. There's even an "address autoconfiguration" method by which your device can configure its own IPv6 address without the need of a DHCP server at all. (By the way, Vista already supports DHCPv6 and Mac OS X supports IPv6 autoconfig.) Since you're being given a whole "prefix" (the IPv6 equivalent of an IPv4 "subnet"), there's no need for sharing one address and thus no need for "Network Address Translation" (NAT).

The people who design the protocols which run on the Internet (the "Internet Engineering Task Force" or IETF ) actually, in general, don't like NAT because it complicates a lot of protocols. Think of all of the protocols which you've heard "have problems passing through a NAT." If we can get rid of NAT with IPv6, we'll be a lot better off. (One address space to rule them all!)

Now, having removed NAT in IPv6 doesn't mean that we also will remove all of the security issues related to current NAT usage. Those same types of security issues will still need to addressed. They just won't be "automatically solved" via NAT and will need to be addressed directly instead. But, that's a whole podcast in itself!

Keep up the good work, guys and gals! Love the show!

IPv6 and routing
Hi guys.

Tom is essentially correct, there are several reasons why you would need to use a router for IPv6

  1. ISPs may do a per-device charging when ISPs are converted to IPv6. This probably is the case, depending on the type of service you have (either residential or commercial). FYI, there are some ISPs that will charge businesses 2x as much under a business plan with lower bandwidth (never did figure that one out).
  2. You would leave yourself vulnerable to attacks within the same ISP network if you don't (people seeing your machines and your shares). Sooner or later, some dunderhead will crack the Wii or the Xbox and plant viruses to detect what device you would have on a network...without a router. I am not saying it's impossible behind one, but just a general broadcasting virus would do major damage (anyone remember code red?).
  3. Considering that not many normal people do not change their machine names in Windows when they get a new Windows PC (owner-pc being a popular one), you would have conflicts and average Joe user wouldn't know how to fix this on his own. Again, goes back to #1 (more staff, higher prices).
  4. Overall privacy . We all open shares etc. to other machines to have easy access to our files between multiple machines in the house and for file storage. It's still my stuff, and you can't have any of it without my permission.
Have a good one.

Routers and IPv6
Tom, you're right on the money. Even though we won't technically need IP routing in a few years, there are a *lot* of advantages of routers beyond IPv4 extending. First, there's privacy. I don't want my Internet traffic from my home or office being tracked down to the device level. Although an ISP can technically see many of the devices behind a NAT router now by examining packet traffic, they would be able to know *every* kind and how *many* devices you have if they can track them by IP. Cable box, DVR, refrigerator, server, toothbrush, computer, etc. Second, a NAT router helps weed out nasty incoming virus, bot, and spammer connections. While that's primarily a firewall function, it's very useful.

Use of NAT in IPv6
Hi Buzz Out Loud crew,

Gideon from Philippines here. Been listening to the show for more than a year already.

I could think of one good reason why NAT is still useful on IPv6 like it is on IPv4: security. NAT is the simplest way to prevent the users from the public Internet to be able to access your private internal network. Plus, if all your computers and devices are behind a NAT, you're basically blocking all inbound vulnerabilities on your OS, or other software can be exploited remotely.
