Mac OS X Server comes with a number of DHCP options available; most notably the options available in the GUI. But what about options that aren’t available in the GUI, such as NTP. Well, using /etc/bootpd.plist, the same file we used to define servers allowed to relay, you can also define other options.These begin with the following keys that can be added into your property list.

If you want to determine the IP address of the DHCP server from which a Mac OS X system received its IP address, subnet mask, etc., you can obtain that information from a command-line interface (CLI), i.e., a Terminal window by using the command
ipconfig getpacketinterface where interface is the relevant networkinterface, which will usually be en0 or en1 .You can issue the command ifconfig -a in a Terminalwindow to see the network interfaces on the system and which haveIP addresses assigned to them.
getpacket interface-name
Prints to standard output the DHCP/BOOTP packet that theclient accepted from the DHCP/BOOTP server. This command isuseful to check what the server provided, and whether thevalues are sensible. This command outputs nothing ifDHCP/BOOTP is not active on the interface, or the attempt toacquire an IP address was unsuccessful.
When you issue the command, you will see output similar to that shownbelow:
Mac Os X Dhcp Server Download Windows 10
Some of the values displayed include the following:
You can also use the ipconfig's
getoption parameter to getspecific values individually.
Os X Dhcp Server
getoption interface-name (option-name | option-code)
Prints the BOOTP/DHCP option with the given name or optioncode integer value. Steam download unblocked at school mac. See bootpd(8) for option code names. Ifan option has multiple values e.g. Photoshop cs5 for mac download bittorrent. domain_name_server, onlythe first value is printed. Dhcp Mac Address
E.g., the commands below get the DHCP serverIP address, the router's IP address, the subnet mask, and the domain nameserver's IP address. In this case the router is also functioning as the DHCP server and DNS server. You can also get the lease time in seconds and thedomain name, if one has been assigned, though in the example belownone has been assigned. The value below of 86,400 seconds for the lease timemeans the lease of the IP address is good for 1 day, since86400 / 24 / 60 / 60 = 1. When the lease time expires, a system has to querythe DHCP server again for an IP address and associated information. It mayget the same IP address again.
