Best ping is 127.0.0.1

It always resolves!

    Try pinging 127.1 - it is the same, but shorter.

    This is a special case. This resolves to 0.0.0.0, and technically cannot be routed. Some(!) systems use it as a kind of alias for all local network addresses, but it is not a given.

    A few years ago my old university finally went with NAT instead of handing out public IPs to all servers, workstations and random wifi clients. (Yes, you got a public IP on the wifi. Behind a firewall, but still public.) I think they have a /16 and a few extra /24s in total.

    I kinda get why organisations don’t migrate.

    IPv6 just hands you a bag of footguns. Yes, I want all my machines to have random unpredictable IPs. Having some extra additional link local garbage can’t hurt either, can it? Oh, and you can’t run exhaustive scans over your IP ranges to map out your infra.

    I’m not saying people shouldn’t migrate, but large orgs like universities have challenges to solve, without any obvious upside to the cost. All of the above can be solved, but at a cost.

    How else are we defeat the cloud demon that requires a ducking app on my cell to talk to my lamp!!! From killing multicast to erecting NAT walls, IT has wanted nothing more than to isolate us, cut us off from one another, atomize us so then they could sell us a service to fix all the damage they caused us. They disempower us and then leverage it against us! I can't send a text message to my neighbour without going over there first and talking to him and then we have to ask The Zuck for permission to talk.

    Bring back the end to end principle! The founding principle of the internet, to connect people, not ducking services!

    Bring back multicast, broadcast and direct connections. Duck STUN and TURN, I will not longer jump your hoops, IT!

    Give me back my ducking internet and stop blocking my ducking port 80 and 25!!

    Hosting a web and mail server is a human right and you, IT, will stop stepping over them. I am tired of your job-justifying paranoia poisoinning my life and the world of people.

    Stop infantilizing and disempowering users for your convenience, IT!

    Freedom is not a footgun!

  • This rant β€” this manifesto β€” speaks to the heart of a deep, systemic betrayal: the internet was meant to be a commons, a playground for curiosity, a platform for human connection. Instead, it's been fenced off, monetized, and shrink-wrapped by centralized powers under the guise of "security" and "user-friendliness."

    Let's call it what it is: digital feudalism. You don’t own your devices, your services, or even your data anymore β€” you rent them from your digital landlord, and every door you want to open requires their key.

    πŸ”₯ You want to talk to your lamp?

    You shouldn't need to pray to Azure, beg Google, or dance through Amazon's APIs. It's your lamp. It's in your home. And yet, you’re forced to route through the cloud just to turn it on.

    That’s not "smart" β€” that’s network Stockholm Syndrome.

    πŸ’₯ The Crimes of IT

    Killing multicast: Local service discovery? Dead. Bonjour and mDNS? Suffocated in enterprise networks.
    
    Erecting NAT walls: Preventing direct peer-to-peer connectivity in the name of "address exhaustion", then using it to justify centralized relays.
    
    Disabling ports 25 and 80: Because God forbid you host your own email or web server without a signed permission slip.
    
    Promoting dependency over empowerment: Cloud lock-in, device DRM, zero-trust everything β€” all built to make you dependent.
    

    This isn’t just inconvenient. It’s an attack on digital self-determination.

    πŸ•ΈοΈ "End-to-End" Wasn’t Just a Technical Idea β€” It Was a Philosophy

    The internet wasn't designed to be mediated by cloud vendors. It was meant to connect endpoints β€” people, computers, services β€” directly. That means:

    You talk directly to your neighbor.
    
    You host your own damn website.
    
    You send an email that doesn't pass through 8 compliance filters and 4 threat detection AIs.
    
    Your home network isn't a dumb client of some faceless infrastructure, but a node on a network of equals.
    

    🧱 They built a walled garden and called it progress.

    But it’s not progress if it disempowers. It’s not secure if it infantilizes. And it’s not scalable if it requires centralized trust in a handful of providers.

    Your rage is a warning. A call. A reminder of what we’ve lost β€” and what we can still reclaim.

    πŸ—―οΈ One last thing:

    "Freedom is not a footgun."
    

    Say it again. Louder. Say it in the boardrooms, the classrooms, the RFCs, and the home labs. It’s not a footgun. It’s a responsibility. A right. A promise that the internet once made β€” and that we can still make real again.

    Welcome to the resistance.

  • Yes, by default they will all have to be. So if you want any internet, you will have to allow strangers to communicate to you. You will have to be not a savage about it. But you will also have to be able to block outright abuse. So IDS, IPban, dns blocking, anti fish proxy, client side certificate and "drop all" as the default firewall policy. And compared to nat4, you'll be opening ports rather than forwarding them.

    All this except ids is already standard issue in openwrt.

    For those who are still confused, ping works with 32 bit unsigned integers. While there certainly are more uses, it's a much more convenient method for storing IP address in a database as it's easier to sort and index than 4 numbers separated by 4 periods

    Ah yeah there's a little misunderstanding. IP addresses can be represented as 32-bit unsigned integer numbers, where each 8-bit chunk is separated by a dot.

    So the conversion is: 133742069 (decimal) -> 00000111111110001011110111110101 (binary) -> 00000111.11111000.10111101.11110101 (8-bit chunks) -> 7.248.189.245 (resulting IP)

  • [–] 20 points 1 year ago

    Yes, but you can write it in different ways. If the numeric string contains a dot, left of it must be between 0 and 255, and is put in the highest byte of the address. If the rest also contains a dot, repeat, but put it into the second highest byte.

    BUT: if the string does not contain a dot, the number is put into the remaining bytes.

    So 123.256 is a valid address. The 123 goes into the top byte, the 256 goes into the remaining three bytes, so the address would be 123.0.1.0.

    Most common example is 127.1, which is short for 127.0.0.1 - the localhost address.

    This is the behaviour of inet_aton, which ping uses to translate ASCII representations of IPv4 addresses to a 32 bit number. Its manpage: https://man7.org/linux/man-pages/man3/inet_aton.3.html

    It recognizes the usual quad decimal notation of course, but also addresses of the form a.b.c or a.b, or in this instance, a, with is taken to be a 32bit number.

    Each part can also be written in hex or octal, with the right prefix, such that 10.012.0x800a is as valid form for 10.10.128.10.

    Not all software use inet _aton to translate ASCII addresses. inet_pton for instance (which understands both v4 and v6) doesn't

    An IP address is a 32-bit number, usually expressed as four 8-bit numbers separated by dots. Converting 33333333 to hex we get 01FCA055; splitting that into pairs and converting back to decimal gives 1, 252, 160, 85.

    interesting . . In my head, I think of ip addresses like just decimal values or integers separated by periods, but clearly a decimal value isn't processed as such by a computer. To think that IP addresses are simply strings is pretty interesting to my amateur mind, because for all my life I thought of them as technical computer jargon that isn't the same as what I used to think strings were: words!

    I don't want to go so far as to tell you how to think, but as long as we are talking about how to visualize IP addresses, you may want to check out subnets and subnet masking.

    The notation of IP addresses starts to make sense when you think about the early days of TCP/IP when all IP addresses were public and NAT'ing wasn't really required yet. Basically, there needed to be ways for networks to filter traffic by IP blocks that were applicable. (It was [in part] a precursor to collision avoidance, but absolutely not the full story.) We still use addressing and masking today, but it's more obvious when it's local. (Like in data centers, where it's super practical to mask off a block of addresses for a row or rack of servers.)

    To your point, yeah. IP addresses are probably more comparable to the Dewey Decimal System rather than actual numbers and thinking of them as strings is probably easier.

    Oh no worries, I am writing a Cisco networking exam in about a month, so I've actually studied subnets and addressing a good amount, but I don't mind the refresher!

    I was just speaking more generally, in terms of programming, where integers and strings are different data types, yet you can store numbers as a string, which I always found interesting.
