  1. Re:home routers on IPv6 Traffic Remains Minuscule · · Score: 2

    Are YOU willing to pay an extra $5/mo for IPV6

    I've actually chosen an ISP that provides IPv6 (Free.fr) over a very slightly cheaper one that doesn't.

    It's not that I actually need native IPv6 (Miredo works just fine), but providing native IPv6 indicates that the ISP is likely to be less clueless than its competitors when IPv4 addresses actually start running out. The assurance that they'll still be around next year is well worth the couple Euros I'm paying extra.

    That's 14.57 square kilometers, the size of a small to medium-sized town, maybe 20000 to 50000 inhabitants.

    According to Wikipedia, the Mojave desert is 65,000 km2, which is more than twice the surface of Belgium, or roughly one tenth the surface of France. (Yeah, America is big.)

    A more interesting statistic is the amount of power produced by this installation, 400 MW, which is about 1/4 of a nuclear reactor, or one large wind farm.

    STARTTLS is used between mail servers if:
    • both the sender and the receiver support the STARTTLS extension; and
    • the receiver has been configured with a certificate (even a self-signed one).

    All modern mail servers support STARTTLS, and most ISPs have configured a certificate in their MX. To see if yours has, do the following:

    $ host -t mx google.com
    google.com mail is handled by 50 alt4.aspmx.l.google.com.

    Email is inherently insecure, since it is transmitted in clear text

    Most mail nowadays is transmitted over SSL. Yes, that's still vulnerable to MITM-ing, but it's no longer a simple matter of passive snooping.

    If you're relying on the law to keep your email private, you've already lost.

    Please. Strong privacy laws won't prevent ISPs from occasionally snooping on their users, granted. With no privacy laws, howver, expect your ISP to routinely spy on you, and sell the data to advertising companies.

    I think you're missing the point.

    We're not speaking about switching to pure IPv6. We're speaking of making Yahoo accessible over both IPv4 and IPv6.

    Pure IPv4 ("legacy") sites will have no problem, they'll just contact Yahoo over IPv4. Properly configured dual-stack sites will have no problem, they'll have a choice between IPv4 and IPv6. It's only mis-configured clients that might have problems.

    The article claims that 0.05% of Yahoo's customers are mis-configured. These 0.05% will need to either disable IPv6, or fix their systems. --jch

    Ah, the OSI model [sic, recte suite], [...] having never been implemented!

    Saying that the full OSI suite has never been implemented is like saying that nobody implements the full set of standard track RFCs -- which is true, since some standard track RFCs are mis-designed or even contradict other standard-track RFCs.

    Large parts of the OSI suite have been implemented, and some are still running today. For example, IS-IS over CLNP is commonly used for routing IP and IPv6 traffic on operators' backbones. (I was about to mention LDAP and X.509 before I realised they are not necessarily the best-designed parts of OSI.)

    Where you are right, though, is that large parts of OSI are morasses of complexity that have only been implemented due to government mandate and have since been rightly abandoned.
