Need to find computer name from MAC address


Recommended Posts

Ok so here at the company i work for we have determined that someone has been doing things they should not with the computers and all i had was an ip address and a MAC address and i have tried ARP and NBTSTAT and i am unable to get the computer name from either of the numbers is there another way that i can find the computer name from either the IP address or MAC address.

Depending on your network setup you could also Browse the computer using a domain admin account etc.

Just go to any computer and type \\ipadd\c$ in the address bar of explorer.

This should let you browse the mydocuments folder which should give you enough information to figure out where they are.

http://www.coffer.com/mac_find/ may help you at least determine what kind of device it is.

You really have no WINS, DNS, or DHCP servers? most logs here are small and will often tell hostname requesting the info.

Do you have managed switches to set up port mirroring or if connected to a hub or at least if managed. Disconnect them or thier lan segment as last resort.

You can sniff the traffic.

If you can't get the Hostname using a NBTSTAT -a xxx.xxx.xxx.xxx (replaces x with ip) then the box is either firewalled. Does not respond to because it isnt a PC might be like a router, switch , printer etc.

try http or https to the hosts IP

attempt to telnet to it

try SSH to it.

lastly GO look for strange devices or PC

is your dhcp server a box (computer, windows, linux) or a router (cisco, netgear, etc.)?

If its a windows or linux box, you can look up the host name in the dhcp scope. If you have absolutely no idea what the box is, or who it is, then run nmap on it to see what ports the machine has open and what the make of the network card is. usually that might point you in the right direction.

if all else fails, kick them from the network or quarantine them, and first person who comes and bitches about it, is the culprit.

We know that it is a Dell computer, We know that it has to be wired in (our wireless network has a different IP set) and we know what the MAC address is. Also we know there is no current computer on the network that has the ip address that it had when it was causing problems. I think i might just have to go from computer to computer and check their mac addresses.

Block the MAC and see who complains they can't access the network.

"to go from computer to computer and check their mac addresses. "

Why is that? And why do you need the name? Are you switches not managed? On a managed switch you can always track down what port a mac address is connected too.. Even if the cheapest smart switches support this.

For example from $80 my home gig switch!

Ports with more than one mac address on them have downstream switches connected, etc.

finding what port a mac is connect to on cisco swith is as easy as

show mac-address-table | inc partofmacaddress

Once you no the port -- go to that port and follow the wire and you have your computer ;)

    • Sony unveils its first fight stick 'Project Defiant', supports PC and PS5 by Pulasthi Ariyasinghe In a surprise twist, Sony announced a new piece of hardware at its State of Play presentation today. Currently going by the codename Project Defiant, it is Sony's first attempt at making a fight stick. Considering the company is currently partnered with Marvel to make a first-party fighting game featuring heroes and villains from the popular comic universe, this seems to be the right time to unveil the project. As seen in the teaser trailer above, the wireless fight stick follows the modern black and white PlayStation hardware style of the consoles and standard gamepad controllers. The controller will ship with a toolless design for changing the restrictor gates, with square, circle, and octagon options incoming for the stick. Meanwhile, the buttons are confirmed to have mechanical switches. Plus, a dedicated touchpad, much like on the DualSense controller, is available on the top of the fight stick. "It’s built in a sturdy, ergonomic design for a comfortable feel during intense fight sessions," adds the company. Sony is leveraging its PlayStation Link technology in the device. With it, the company is promising ultra-low latency wireless connectivity, making sure it provides players "precise in-game response to each button press and digital stick movement." Interestingly, PlayStation Link is Sony's proprietary wireless connectivity standard designed for PlayStation 5's audio transmissions, which is now being used a little differently for this piece of hardware. The controller has built-in storage for holding both the restrictor gates and the PS Link USB adapter. As expected, a wired connection is also possible, with a USB-C port available on the device for connecting to a PlayStation 5 or PC. To make sure the device remains in good condition during travel, Sony is throwing in a sturdy sling carry case with each Project Defiant fight stick. More details, like the official name, internal hardware, release date, and most importantly, price, will be revealed later. The hardware has a 2026 launch window right now.
    • Precisely. I didn't give Reddit permission to sell my posts to any AI vendor from any of my accounts. Since I've been on Reddit since before the current pseudo-AI existed, I don't think anyone did...
    • The character tech looks awful, like something from 10 years ago.
    • lol net-negative? They're worth $29 billion, so they aren't hurting. They're just money hungry and don't care at all about the free videos on their platform. They shouldn't be making money off of those, but they are. Those content creators that are uploading their videos they made aren't making anything, but YouTube is making tons of money off of them, along with being exorbitant. If they want to do what they did before and lock Premium videos in a paywall, then fine. But no one is going to put up with them strong-arming people into paying just to have an ad-free experience while watching super old videos uploaded by John Doe at 360p.
    • Sony unveil Marvel fighting game 'Tōkon: Fighting Souls' for PlayStation 5 and PC by Pulasthi Ariyasinghe Sony held a massive surprise in store for those who made to the end of its State of Play presentation today. Coming in as a collaboration between PlayStation Studios, Arc System Works, and Marvel Games, Tōkon: Fighting Souls is slated to be a tag team fighter featuring everyone's favorite heroes and villains from the Marvel comics universe. Watch the debut trailer above. Developer Arc System Works, which has previously worked on series like Guilty Gear and Blazblue, has revealed that the focus on this project was making sure it was easy to pick up and play by anyone. To put this into perspective, the studio says that while other fighting games require learning each character's moves to play them effectively, Tōkon will only have one way of playing for all available fighters. "From the beginning, we aimed to make MARVEL Tōkon: Fighting Souls a title that could be enjoyed by a wide variety of players," explains Game Director and Lead Battle Designer, Kazuto Sekine. "We have designed the mechanics in such a way that you can perform a variety of actions with either traditional fighting game inputs or simple inputs. With the press of a few buttons, multiple characters can appear on screen to provide backup or attack together – creating a new and exciting team VS battle experience." So far, Captain America, Iron Man, Spider-Man, Doctor Doom, Storm, Ms. Marvel, Star-Lord, and Ghost Rider (Robbie Reyes) have been revealed as playable characters, neatly filling the trailer's four versus four battle. Each character has a Japanese flair to them too, such as Iron Man's unique Gundam style for his armor. As for why the studio went with the 4v4 Tag Team battle solution, the team said that the team-up nature of superheroes was the inspiration for that, making sure that players can fill the screen with all sorts of powers they are familiar with. Tōkon: Fighting Souls is coming to both PlayStation 5 consoles as well as PC sometime in 2026. More announcements with reveals for characters, stages, gameplay modes, and online mechanics will be coming up until launch as well.
