In this article, we’ll show you how to find all ip addresses on a network along with device vendors using MAC addresses with different methods for free. But RARP is an obsolete protocol with many disadvantages, so it was quickly replaced by other protocols like BOOTP and DHCP, which deal directly with IP addresses. Or your computer is unable to display its IP due to various reasons, and you are getting a “No Valid IP Address” error.įinding the IP from a known MAC address should be the task of a ReverseARP application, the counterpart of ARP.
You might be in a situation where you don’t have the IP address of a device in a local network, but all you have is records of the MAC or hardware address. If I don’t use quotation marks (” “), Terminal will only use the first word (Ankur) and ignore the rest (M1 MacBook Pro).Īs always, feel free to ask if you have any questions.How would you communicate with a device when you don’t have the IP? For example, to rename my Mac to Ankur M1 MacBook Pro, the Terminal command will be sudo scutil -set ComputerName "Ankur M1 MacBook Pro". Note: If you want to set a computer name that has spaces, enclose it in double quotation marks (” “). sudo scutil -set ComputerName YourNewComputerNameĥ) Reboot your Mac if the new name doesn’t reflect in System Preferences > Sharing. Rename your Mac with Terminalįor those that are comfortable with the command line, you may use Terminal to set a different name for your Mac.Ģ) Type in the following command, making sure to replace YourNewComputerName with the name you want to set. On macOS Monterey and earlierġ) In the menu bar, go to > System Preferences.ģ) In the Computer Name box, type in the name you want to use for your computer.Ĥ) Close the window, and you’re done.
These steps will work to change your Mac device name, no matter what Mac you’re using (iMac, MacBook, MacBook Pro, Mac Pro, Mac mini, Mac Studio, etc.) On macOS Ventura and laterġ) Click the Apple icon () and choose System Settings.Ĥ) Add the new name in the Name field. If not, I’ll show you how to do just that. The steps to set or change your Mac’s name are quick and easy, but I figured that if you already know how to do it, maybe this post will be a reminder for you to check that your Mac has indeed been given a name that makes sense to you. I wasn’t sure how that happened, but I knew I wanted to have a proper name for it just so I could recognize it when looking for it on the local network or when sharing files and documents with it over AirDrop. When in Find My iPhone, it would just show up as Unknown. While working on a series of posts about Find My iPhone, I realized that my iMac didn’t have a specific Computer Name attached to it. Changing the Computer Name of your Mac is a great way to not only personalize it but, more importantly, to easily locate it within a network when multiple other Macs are present.
