When you power on a diskless client or a VoIP phone, a four-step dance occurs: client_addr): opcode = struct.unpack('!H'

Now any PXE-enabled client on that subnet will boot from the network automatically. then use HTTP(S)

is a popular open-source firmware that extends PXE—it can still get initial network info from DHCP, then use HTTP(S), FTP, or iSCSI for faster and more secure downloads.
