command-line-interfacedhcpmac addresswindows
From my computer, I want to query my DHCP server to find a specific mac adress.
I want to enter the hostname to search, and getting back the Mac address.
Something like :
netsh dhcp server scope show clients |find hostname
This command line doesn't works, but maybe you have some tips ?
Thank you,
Windows systems that are members of a domain can automatically register their hostname in the domain DNS; but this can be done only by Windows systems.
Microsoft DHCP can be configured to register DNS names on behalf of those clients which can't do that by themselves (like Linux ones); this is what should be done if you want your device to automatically appear in your DNS. You can configure this on the DHCP server's properties.
Be careful, though, as this will mean any client will get registered in the DNS if a DHCP lease is handed to it.

If you are comfortable with Powershell, this script will help you find what you need: https://sites.google.com/site/assafmiron/ServerScripts/get-dhcpleases
This script almost works as well. It currently lists extra clients. Some regex magic with the find command parameters could fix this. Save to to a .cmd file and specify your dhcppserver and a valid scope.
Output should look like this
