    They should have just like doubled ipv4 so 192.168.1.1.1.1.1.1 at least that would have made sense

    IP addresses aren’t meant to be consumed by humans, that’s what DNS is for. That being said, nothing stops you from converting IPv6 addresses to that format. Two “digits” in an IPv6 address correspond to one block in IPv4.

    Also what people don’t understand is that the huge address space is not meant to to be exhausted. It provides “layers” with significant reserves to make routing easier and flexible.

    Nothing is wrong with NAT

    Except everything


  • but we’re almost out of numbers.

    We are out of numbers. Just because technically there might be some unassigned or even assigned but unused numbers doesn’t mean we didn’t run out of them. There are more devices in the world connected to the Internet than IPv4 addresses exist. If you read this sentence from the standard strictly:

    The internet protocol provides for transmitting blocks of data called datagrams from sources to destinations, where sources and destinations are hosts identified by fixed length addresses.

    This isn’t the case with NATing as hosts are no longer identified be the address alone (but additionally other parameters like port number or TCP connection status). You can’t ICMP ping a NATted host to my knowledge because it operates on IP directly (it’s actually part of IP itself). So parts of the protocol become unusable. So just by logic, we have run out. The last remaining blocks won’t fix the issue, and rather make routing worse than it already is.






  • Right?

    Are these right wing politicians living in their own bubble or am I? Why would anyone want to be associated with the US administration in general and Vance in particular at this time? Who looks at this and thinks “oh, the venerable vice president of the United States endorses this guy, surely I’ll give him my vote”?

    There have been about 0 good news from the US in the last year. If I were a politician I’d distance myself from that trainwreck so hard











  • I’d pirate it but I find the story just not interesting or worth my time.

    I read Philosopher’s Stone about 25 years ago as a teenager and wasn’t impressed. Didn’t read any other because that one already felt like wasted time. Went to a movie in 2007 (no clue which one that was) and again forgettable. Not bad, in fact I still remember Die Hard 4 that I also watched back then because it was so bad. That HP movie? No idea about plot or anything. Another one? Thanks, I’m good.

    Even if Rowling wasn’t a disgusting person, I feel like what I’ve seen of her work is just not great. It’s not terrible, but I don’t care for it at all.

    But also, she can get fucked.
