I joined Lemmy back in 2020 and have been using it as qaz@lemmy.ml until somewhere in 2023 when I switched to lemmy.world. I’m interested in Linux, FOSS, technology, and several other subjects.

  • Ip address doesn’t expose where you live.

    https://letmegooglethat.com/?q=geoip+lookup

    Tunnels stop you from opening a port so nothing is exposed openly to the internet1 but it does not keep your ip private2.

    This is also incorrect.

    1. The entire purpose of CF tunnels is to expose sites on the internet
    2. CF tunnels (and services like it e.g. ngrok) rely on shared proxy servers that forward traffic based on HTTP host headers (which is why you can’t forward arbitrary TCP traffic). The IP of the site will therefore have the shared IP of the company’s proxy server instead of your own.

    Yes, but if you host a public site it might be a better option, the content is public anyway, and you won’t get doxed if you publish something controversial. It’s a trade-off, between keeping traffic private or keeping your IP private. Wireguard works best for private traffic, but you can’t host a public site with that.

    There is IPv4, it’s an internet address that points to a specific computer, or at least it’s supposed to. IPv4 supports up to 4294967296 addresses, which might seem like a lot until you realize how many devices are connected to the internet. Almost the entire IPv4 range is full, and ISPs have resorted to letting 1 IP point to multiple computers also known as NAT. It’s what your router does, and why your laptop and phone all connect to the internet using your routers’ IP address. Carrier Grade NAT takes it one step further and allows hundreds or more home networks to connect from a single IP address.

    CGNAT kind of sucks because you can’t run servers behind them because it doesn’t know which of the hundreds of computer traffic has to go to. IPv6 would solve this entire mess, but ISP’s won’t invest in it because they don’t want to spend the money and just delay the inevitable until they have to.
