If I am standing physically next to an active server, but I cant

Depends what the server is used for, whether it's cloud "based" or not, and what tools you have at your disposal.

Quickest way could be to gain physical access to one of the right ports.

Why do you ask OP?

open a browser
open google
type "what is my ip"

you have to psychically connect with the server

see the mac address and ask the isp of this

When ask what ip, you have to ask which interface has this IP?

So if it's an ethernet port, you can find it by jacking in and running tcpdump.

That's only if he's connected to it though.

You probably can't find out the IP address.

Then again, from experience, I know that some IT guys actually give servers static IP addresses and often put a sticker on the server with aforementioned IP address. Look around, maybe there's an IP address written on it.

It is generally a common practice to give servers static IP addresses and to write such addresses down.

OP get out of your middle school's server closet and get back to class.

>>60227049
Run a script that loops through all IPs and hacks the computer so it plays a tune then when the tune appears on the server you can just check what IP you were hacking and you know the IP of the server

Insert dick in a port than you will be physically connected than do what other anons said

Guys like you are the cancer that's killing /g/.

OP is a joke though. Why is he asking such a shady question? Sounds like he's not supposed to be in that server closet if he doesn't know how port hijacking works.
