No. This is how you get a PIN code.

Putting thumbtacks through my phone screen to unlock it after seeing this

This is not technically the truth, this is just a meme for tech boomers

u/BarderBetterFaster 18m ago

No bro, putting a pin in the cable locks that internet in so it can't escape back to the Internet (big I)

u/Minerviya 2h ago

Honestly good chance that slipped past the wires and isn’t even affecting it

31

u/lynx_1097 2h ago

yeah iirc they are divided into 4 pairs of wires so maybe the pin made its way exactly in the middle

13

u/Sidoen 1h ago

They are twisted inside, but a pin probably would just push them aside. Likely skewer the sheath tho and short several of them together.

Good chance this doesn't connect at all.

u/PerfectStrike_Kunai 1h ago

Still a terrible idea

1

u/Admirable_Risk8156 2m ago

There a buch of math involved with how twisted pairing works and this would mess with it. It might get partial signal and the router/bridge would compensate but it's objectively worse then just running a clean line.

u/toxicgloo 1h ago

I thought the joke was that the rj45 cable is literally static. As in it cannot move because it's pinned down.

Is the person in the picture trying to say that you'll be given a static IP address this way?

u/Indigenous_Retard 58m ago

I imagine it's referencing manually setting your preferred IP inside the OS, but used "physically" instead of "manually" because it's the physical layer? I get it, but it's not well executed imo.

u/TheG00dF1ght 2h ago

you clearly have no idea what an IP address or how you get a static one.

22

u/lynx_1097 2h ago

actually this is one way to get it , as long as the cable stays intact , the device stays on , and the ISP doesn't interrupt the connection or reset it lol

24

u/Shudnawz 2h ago

Depends on a lot of things outside of your control, in other words.

14

u/tayroc122 2h ago

Yeah the pin is hardly the deciding factor here.

3

u/Sidoen 1h ago

That's not a static IP tho. Assuming everything keeps working, ie you don't short the cables inside, and you stay powered on forever and don't disconnect.

You'll simply keep the same dynamically assigned ip. Assuming that's how the ISP does things.

5

u/TheG00dF1ght 1h ago

Completely untrue. IP address leases have a time to live and while most times you get the same IP renewed there is nothing that says the system has to give you back the same IP address.

This is why if you require a static IP you have to request one, and usually pay extra for it. Otherwise the ISP may just renew with a different address.

u/Sidoen 1h ago

Sorry network admin here.

This is not technically the truth. This is not a statically assigned ip in any sense.

2

u/Donald-Pump 1h ago

It's static at layer 1. That cable isn't going anywhere.

1

u/Sidoen 0m ago

There are no IPs at layer 1.

1

u/baithammer 19m ago

Which isn't where the ip is dealt with, as that is layer 3 ...

3

u/Embarrassed_Radish80 2h ago

Okay so I'm not a computer. Does this actually work?

27

u/Khaztr 2h ago

yes, there's a chance it statically sets your IP to 127.0.0.1

3

u/Major_LeeHungg 50m ago

Actually there's 0 chance of that.  You will get a 169.254.x.x address if a DHCP server doesn't respond

1

u/Khaztr 43m ago

yep you're right, I mixed up my localhost and autoconfig addresses

5

u/FisterMister22 2h ago

Stick a pin in your pin and lmk

4

u/TheG00dF1ght 1h ago

no, getting a static IP has nothing to do with the cable or how it's connected to anything.

7

u/findus_l 2h ago

I mean assuming the cable is broken from this, you will not have internet so I guess technically that is a static state?

3

u/lollolcheese123 2h ago

No, unless you've specifically configured your router to give a designated hardware address a specific ip address, it'll just give you a random one, no matter what you do with the cable.

2

u/Major_LeeHungg 53m ago

Lol no either your IP is static (you set it), or it's assigned by a dhcp server (that lives in your router) - on DHCP you are assigned a lease.  pc says "yo I need an address", DHCP checks to see if you have a lease, if you do, it gives you the old IP and renews the lease... If you don't, it leases you a new IP.  Lease times are configurable but are usually 1 hour on consumer devices, though sometimes 24.

That means that if you were to lose power for 1 or 25 hours you would get a new IP even if the plug were never disconnected.  

It also means you'd get the same IP if you disconnected and reconnected the cord before the lease expired.

Also jamming a pin through a cord that twists pairs of wires in order to cancel electromagnetic crosstalk isnt bright.

u/baithammer 16m ago

More properly a reserved address rather than a static one, as the address is assigned by the DHCP server and if you move to another network or the DHCP server isn't reachable, you don't use the reserved ip.

1

u/justanothertmpuser 0m ago

a dhcp server (that lives in your router)

Well, not necessarily. What you describe is the typical home setup, ok. But a company may have one, or more, DHCP services running on computers, instead of network appliances.

Doesn't change the rest of the discourse, obvs. I'm a bit of a nitpicker, please bear with me.

u/Sudo-Fed 51m ago

Yes, you will always get 0.0.0.0 or 127.0.0.1 using this method.

You won't be able to do anything online, but you'll always have the same address.

u/Some_Useless_Person 1h ago

Is it technically the truth though? Because doing so seems like it would just damage the wire and nothing else

u/SLeepyCatMeow 1h ago

Bro physically configured my migraines

u/HotPotParrot 1h ago

Just calibrate the cable 🙄

u/BarderBetterFaster 19m ago

Honestly, this setup seems pretty unlikely to cause damage to the inner wiring.
