Maythux Maythux Why do you place! It is not necessary and only used in cases where the question is shouted or of high importance. Try just: sudo nmap -sn Or as man nmap says: sudo nmap -sn This will need to be adjusted so that I don't know if that is the reason, but on Linux I use nmap -sP Do you know why root priveleges are required to read MAC addressees from the network? Edit Per davidcl's comment, this answer isn't as perfect as I'd first hoped. Just to play through the arguments quickly But what about hackers in my network?!
They can block all responses to every type of scan. Oh but surely nmap is still best possible solution When run here, it's still missing out four devices. Four devices that are active on the network. Either they're not responding to the pings or nmap isn't waiting long enough for them to respond I don't know. And don't call me Shirley. Maythux For all network users its origin is generally unknown, so no, it can't.
Ruslan That's just paranoid me blanking them out I'm sure it would be fairly hard for an individual to do anything with them but you never know who's stalking you. I'm surprised by this answer. If there has been no communication between the local machine and another machine on the network recently, that machine will not show up in the "arp" listing.
If the computer running arp hasn't received a packet from another device, it won't be on the arp list. I'd be interested in knowing more about the devices that nmap failed to detect on your network; there are ways to hide from nmap but I've found the default nmap scan pretty effective. That said, There's no failsafe answer because if a device isn't generating traffic and isn't answering requests, it is invisible-- but most devices will answer some type of request. Eric Carvalho Yes, arp-scan is indeed the "best tool for the job". This isn't working for me You can use arp-scan.
TCP/IP networks track IP addresses and MAC addresses
This isn't finding a device that doesn't have an ip yet GUI You can try avahi-discover. Install it with this command or by clicking the above link : sudo apt-get install avahi-discover Run Avahi Zeroconf Browser or avahi-discover from a terminal. You should see a window with a list of devices on your local network. The MAC address will be the string in the square brackets.
Command line You can use this command in a terminal: avahi-browse -a -t -d local It is installed by default. Does this work to show the MAC address of a machine that is not running any services of any kind? In my case this doesn't work for every device on the network.

Does it query sequentially or in parallel? This only works for those devices that have been connected to e. Featured on Meta. Congratulations to our 29 oldest beta sites - They're now no longer beta! Unicorn Meta Zoo 7: Interview with Nicolas. Linked Related 3.
Hot Network Questions. Question feed. For more advanced users, nmap is an even better option for a network discovery tool, but nmap requires installing either directly, compiling through source, or through something like homebrew. The above ping and arp trick will find and list all IP addresses of any devices or computers on the network. This means the IP address of any same network connected Mac computers, Windows PC, Linux machines, iOS devices like iPhone and iPad, Android phones and tablets on the same network, even set-top IP enabled boxes like an Apple TV or Playstation will be found, assuming those devices and computers are connected to the same local network as the computer doing the searching.

Find the MAC Address of a Computer or Device
Enter your email address below:. This can be used in unix systems. In what kind of situation would you use this? What would you be trying to find out and why?
There are many situations this can be useful, from network discovery to connecting to network resources. Same idea with networking to some Windows machines too.

Another great use of this tip is to find the IP address of an IP camera when first setting it up. You should always ping the network broadcast address and then run arp -a for the most up to date list. That is, unless you have already contacted other network machines, then it will be up to date with hardware.
Every device will show up on the arp list though, not just computers in the networked sense. That means the Windows, Androids, iPhones and iPads too. Name required. Mail will not be published required. All Rights Reserved. Reproduction without explicit permission is prohibited.
