Every device on a TCP/IP network has a unique number assigned to it called the MAC (Media Access Control) address. The MAC address is used by the network hardware such as routers, switches, etc. To send traffic from one device to another device on your network.

• What Is The Mac Address

I think you require to supply more information. Are you attempting to do the name/ip search for on some other machine than the one whose Mac pc address you have got? The translation bétween IP and MAC addresses is definitely done using the address resolution protocol (ARP) - the command-line program to check out the windows ARP cache will be simply 'arp' (test arp -a to discover current cache items) You'll possess to have got a machine on the exact same LAN portion, at minimum, because past á router, I wear't believe you can gét to them.

Mac computers can get malware the same as a windows computer. That's why a good anti malware for mac is very important. We recommened using a malware scanner regulary to avoid having any issues with your mac. Compact and efficient: Malwarebytes Anti-Malware for Mac takes up little space on your computer.

Start at the router or L3 switch that holds the IP to MAC address in the ARP cache. That's step one. You need the MAC address. You can get that from the ARP cache. TCP/IP computer networks use both the IP addresses and MAC addresses of connected client devices. While the IP address changes over time, the MAC address of a network adapter always stays the same. Looking up an Internet protocol (IP) address by directly pinging a MAC address is not possible. However, there are several ways to determine an IP address from a MAC address. An IP address is the unique address of any computer that is connected to the Internet or to a local intranet connection.

ln any situation, ARP is certainly developed to move from IP to Mac pc, not the additional way around, so I put on't know if there't a common way to go about the change. Originally published by euzeka: Even more or much less. 'arp -a' will list everything in the ARP dining tables. So you might find what you wish there.

I put on't understand about a scripted way though. Just 5 systems are shown in that desk and generally there's various hundred computer systems on the network. I can see all of them in home windows networking as it's one subnet. I doubt generally there's reverse dns. What it is is usually a coworker is functioning in SQL machine. She gets mac handles detailed with remotely run hung procedures and wants an simple way to discover the computer responsible.

I'meters attempting to create a software to determine the computér with that mác address. A group or vbscript (or anything that offers a built in interpreter in home windows xp) I can appear into nmap I assume.

If both your device and the target machine are on the same subnet, you can just ping it to result in its IP⟷MAC association to end up being authorized via Deal with Resolution Process (ARP). Ping -d1 $IP arp -n grep $IP for illustration if I want to discover the IP óf 10.1.135.150: # ping -c1 10.1.135.150 PING 10.1.135.150 (10.1.135.150) 56(84) bytes of information. 64 bytes from 10.1.135.150: icmpseq=1 ttl=64 period=1.88 ms - 10.1.135.150 ping statistics - 1 packets transmitted, 1 obtained, 0% packet loss, period 0mh rtt minutes/avg/max/mdev = 1.883/1.883/1.883/0.000 ms Then query the ARP table # arp -d grep 10.1.135.150 10.1.135.150 ether 8c:ae:4c:f4:4d:e1 M eth0 So the MAC of 10.1.135.150 is usually 8c:ae:4c:f4:4d:e1.

If you begin with a MAC address, you very first need to get thé IP addréss. This indicates that you require accessibility to a gadget that provides the IP address connected with the Mac pc. As per the issue, arp -a will listing the MAC tackles and matching IP tackles. In purchase to fill that listing, the device will have got experienced to at some stage issued an arp demand, stating 'who offers IP x.x.x.x' - the owner will answer back and upon invoice, the arp table will be populated. In order for this to work, both gadgets must become on the same layer 2 network - the same change/vlan.

You can bring about arp requests manually by pinging évery IP on thé network, or making use of a power like nmap to perform them all in one move. As soon as you have the IP address, you are depending on a title resolution provider to perform a change search engine and return a hostname that is associated with an lP. ln DNS this is usually accomplished through PTR information. For each lP address, there can be a PTR record in which is stored the associated hostname. However, there is no responsibility to store PTR information therefore they may not really be existing, in which case the look for will fail. They look like this: 13.12.11.10.in-addr.arpa. 900 IN PTR hostname.area.com.

What Is The Mac Address

The lP address in thé PTR report can be reversed. So to get thé hostname of 10.11.12.13, we state to DNS 'Provide me the PTR report for 13.12.11.10.in-addr.arpa.' It returns the above record. You can achieve this in by carrying out nslookup 10.11.12.13 When nslookup is provided an IP addréss, it will attempt to perform a PTR hunt. As per the additional answer, if the IP belongs to a Windows device, you can also do nbtstat -A 10.31.46.59 (be aware the uppercase -A).
