IP Address Shortage

Posted by ryuzaki0 on from the stuff-to-think-about dept.

webslacker wrote in to send us a news.com story that talks about the upcoming IP Address Shortage. Talks about IPv6 and other related topics. Nothing phenomonal, but its interesting... how many class C's do we have left anyway?

  1. Classful naming by shani · · Score: 5

    This is a plea, from me personally, and also from me as an employee of ARIN.

    Please stop using classful naming. Class A, B, and C really don't have much meaning these days. Use CIDR - it's more specific and just all-around better.

    $0.10 Tutorial:

    Class A is a /8 (e.g. 10.0.0.0/8)
    Class B is a /16 (e.g. 192.168.0.0/16)
    Class C is a /24 (e.g. 192.149.252.0/24)
    Single IP is a /32 (e.g. 206.170.14.74/32)

    There you go. I'm sure you can figure out how other networks are specified. For instance, the network slashdot is on is a /23:

    206.170.14.0/23

    Isn't that better than saying "two class C's"?
