Windows Server DHCP server reservation list

  • 772

In Windows Server acting as a DHCP server, how can I get a list of the DHCP reservations from the CMD? I need to know

  • the MAC address and
  • the IP address reserved to that MAC address inside the DHCP server.

Right now I have to right click every single item and go to Properties.

dhcp windows-command-prompt

  1. Since Windows Server 2003 there has been netsh dhcp server. You need a command prompt with administrative privileges to use it. E.g. for the list of the DHCP reservations:

    netsh dhcp server scope 192.0.2.0 show reservedip

    Or from another machine:

    netsh dhcp server \\SERVERNAME scope 192.0.2.0 show reservedip
netsh dhcp server <ServerIP> scope 192.0.2.0 show reservedip

    If you don't know the scope address, you can list all scopes on the server with:

    netsh dhcp server show scope

    Or you could even export the whole server configuration into a file (only on the local server):

    netsh dhcp server export c:\temp\dhcpdb

    The netsh has its documentation baked in: you can get a list of commands currently available by giving an incomplete command. You could start with:

    C:\Windows\system32>netsh dhcp server
list                          - Lists all the commands available.
dump                          - Dumps configuration to a text file.
help                          - Displays help.

  2. PowerShell module DhcpServer has Get-DhcpServerv4Reservation:

    Get-DhcpServerv4Reservation -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0

  3. arp -a Shows list of current reservations on your network. Addresses with type=dynamic are reserved addresses
