How To Get A New Ip For Mac Rating: 7,6/10 4327 votes

However, if the computers are connected to the same TCP/IP network, you can determine the MAC address through a technology called ARP (Address Resolution Protocol), which is included with TCP/IP. Using ARP, each local network interface tracks both the IP address and MAC address for each device it has recently communicated with.

For Comcast customers, IP addresses are not static. Your IP address is assigned by Comcast and is an essential part of routing your data from the computer to a website's server.

Unfortunately, this connection can sometimes become slow or cause conflicts with different sites. When this happens, it it is possible to 'roll' your IP address by forcing Comcast to assign you a new IP. These addresses are assigned based on your Media Access Control (MAC) address and are easily changeable using a router.

I thought the aim of this exercise was to FIND an IP address. Doesn't using PING imply you already know the IP (or hostname) which makes ARP redundant?

The X Power offered me the option the first time I hit the house button after setting up the tool: I might either opt for or without the application cabinet. Lg phone drivers for mac.

How do you PING a MAC? Assuming no IP or hostname info, I have used a portscanner (like LanSpy or Zenmap) to get MAC > IP info. Currently my preferred method if the device isn't listed in Spiceworks:-) There was a time when I was a baby admin and I didn't want to raise alarms by installing a scanner that I wrote a batch file (yes, that long ago) that PINGed every IP on a subnet, then immediately ran ARP redirecting output to a text file. But that depends on the device in question being set to respond to PING requests. I realize this is an old topic, but someone like myself may be looking for an answer.

I became admin of a network with little over 200 devices, which none of the cabling was mapped. I was told I was responsible for the cabling, so I began looking for a way other than toning out all the cables. I was fortunate to have Cisco switches and Windows Server 2008. I was able to use the Cisco Network Assistant to grab MAC addresses and the port number, then in DHCP on the Server 2008 I could find the MAC and corresponding IP. Furthermore I could also get the computer name from DHCP and correlate that to which user was on the machine using PDQ inventory to see who was logged in to the machine. Most of this of course depends on the devices being in use. I've been able to create an accurate map of about 90% of my network without touching the cables.

Great for finding an IP if you have the MAC address. My instance where I found this useful was after updating the firmware on a switch remotely via TFTP, the IP of the switch would change (making pinging redundant, obviously). Trying a network scan over Spiceworks or rescanning the single device would not update the IP and I needed an alternate way to find it. This method worked perfectly. Hopefully this helps those trying to understand the purpose of this practice and how it was in-fact useful. I understand the issues in attempting to use a MAC address to locate a device from outside of its local network.
