From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you can't remember the IP address of every site you'd like to visit, you don't deserve the internet.

Pro tip, You don't have to remember it. I have all my favorite IPs in a nice address book, keep it in my drawer next to my passwords

My DNS Rolodex is beside my slide rule and abacus.

My company actually used a whiteboard instead of a DNS for our internal network. We used it as a temp solution during setup, then 5 years later it was still in use. It worked quite well.

Oh, you like the internet? Name every IP address!

0.0.0.0/0

Don't even get me started with IPv6!

Unironically, I used to remember 3.
2 for servers with internet radios and 1 for google. But I forgot. Except 149.13.0.82.

[–] hihellobyeoh@lemmy.world 0 points 8 months ago (1 children)

I remember 1 of the Google dns ones, only because when trouble shooting network issues it is my go to ip to ping so I know the instant I am connected again.

[–] user224@lemmy.sdf.org 0 points 8 months ago

Oh, I forgot about DNS servers. Then I remember:
8.8.8.8 - Google
9.9.9.9 - Quad9
1.1.1.1 and 1.0.0.1 - Regular Cloudflare
1.1.1.2 and 1.0.0.2 - Cloudflare "Malware blocking"
1.1.1.3 and 1.0.0.3 - Cloudflare "Malware and adult content blocking"
45.90.30.180 and 45.90.28.180 - NextDNS

And I think 2960:fe::fe is also Quad9, but I'll have to check. Nope, it's 2620:fe::fe. So just the ones above.

Why are catboys/girls and furries always the best at explaining stuff succinctly?? Lmao

[–] frezik@midwest.social 0 points 8 months ago

Maybe that skill is how they end up with suspiciously high amounts of money.

[–] ultranaut@lemmy.world 0 points 8 months ago

They run the internet now so they really know how it works.

[–] ajmaxwell@lemmy.world 0 points 8 months ago

It's insecure, which lets governments like China poison it. They straight up block encrypted DNS

[–] moon@lemmy.cafe 0 points 8 months ago (1 children)

It's not insecure at all, quite the opposite. Also with DoH, it blends into regular traffic.

[–] iopq@lemmy.world 0 points 8 months ago

DoH is blocked in China, they cut any TLS connection to a known DNS server (1.1.1.1, 8.8.8.8, 9.9.9.9, etc.)

@scroll_responsibly Laughing in my self-hosted services, on my VPS which use only IP address :blobcatjoy:​

*Currently every service is also available via IPv6 :3

My prediction is that we'll go DNSSEC globally when IPv6 gets mainstream adoption. It sucks how many just don't care enough.

[–] domi@lemmy.secnd.me 0 points 8 months ago (1 children)

when IPv6 gets mainstream adoption

At the current speed that would approximately be in 2087.

[–] lolcatnip@reddthat.com 0 points 8 months ago

Whoa there, let's not get ahead of ourselves.

[–] risencode@lemmy.ml 0 points 8 months ago

when IPv6 gets mainstream adoption.

After my death then. Alright, carry on.

CC BY-NC-SA 4.0

This might be funnier than all those Facebook accounts with warnings about "I do not authorize anyone to use my photos!"

Because they're trying to copyright an internet comment that they posted on a service hosted by someone else, with a creative commons license attached. It's like a step up in knowing how shit works, but still not knowing enough.

If you really want ownership over what you say.... don't post it on the fucking internet.

Tbh, if you can't tap out Ethernet frames with a Morse key and decode the response by watching the blinking of an LED wired to the RX pair then you really don't deserve to be on the internet. Git Gud.

[–] smileyhead@discuss.tchncs.de 0 points 8 months ago (2 children)

Okey, I don't get it. What's wrong with DNS?

When it breaks, it isn't always obvious or easy to fix, but can cause problems for anything that has to talk to anything else. The biggest thorn it puts in my side is that short names [ThisPC] are served differently than fqdn [ThisPC.MyDomain.com]. Does NotMyApp use short or FQDN to resolve other machines? I don't find out until the Wireshark.

[–] smileyhead@discuss.tchncs.de 0 points 8 months ago (2 children)

Okey, I understand this is fundamental and when not working can cause the service to stop working. But I don't yet know how does it break or is not easy to troubleshoot?

Haven't hosted anything big yet, so I always just had to check the records via "dig" command if they are served correctly.
