Let’s Encrypt Begins Supporting IP Address Certificates (linuxiac.com)

Who benefits from this? Even though Let’s Encrypt stresses that most site operators will do fine sticking with ordinary domain certificates, there are still scenarios where a numeric identifier is the only practical choice:

Infrastructure services such as DNS-over-HTTPS (DoH) – where clients may pin a literal IP address for performance or censorship-evasion reasons.
IoT and home-lab devices – think network-attached storage boxes, for example, living behind static WAN addresses.
Ephemeral cloud workloads – short-lived back-end servers that spin up with public IPs faster than DNS records can propagate.

Can I get a cert for 127.0.0.1 ? /s

Is that the same i as the squareroot of -1?

The down votes are from people who work in IT support that have to deal with idiots that play with things they dont understand.

[-] kautau@lemmy.world 20 points 1 year ago

It’s unfortunate they don’t know what /s means

[-] spongeborgcubepants@lemmy.world 6 points 1 year ago

It obviously means "secure"

[-] fatalicus@lemmy.world 3 points 1 year ago

We do, it's just that those users will also often go "nah, I'm just joking!" then do some shit anyways.

How do I setup a reverse proxy for pure TCP? /s

[-] Laser@feddit.org 15 points 1 year ago

Think that's called NATing

[-] Lv_InSaNe_vL@lemmy.world 1 points 1 year ago

It's called buying more static IPs and making your ISP deal with it haha

[-] sugar_in_your_tea@sh.itjust.works 1 points 1 year ago

You can based on the port.

[-] Gonzako@lemmy.world 2 points 1 year ago

nah, I was once an idiot who didn't understand so idgaf

Yeah, the unfortunate part about internet security is that everyone has to start somewhere. And that means there’s always a newbie making dumb mistakes that they don’t even realize are dumb. It’s not a personal failing, unless they fail to learn from it.

If you can get their servers to connect to that IP under your control, you've earned it

[-] comrade_twisty@feddit.org 4 points 1 year ago

Nothing a ski mask and a little mission impossible can’t fix :)

This would actually be useful for local testing of software during development.
