DHCP server (Dynamic Host Configuration Protocol)
It is necessary to set an IP address for each computer or equivalent equipment when a network is
established by TCP/IP. If there exists DHCP server on the network, it will assign IP addresses to client
computers every time they request it. If there exists equipment with DHCP server functions (such
as a Windows 2000 server and a dial-up router) on the network, the DHCP server function may be
automatically operating. Ask your system administrator whether the DHCP server is operating.
MAC address (Media Access Control Address)
MAC address is a physical address for every network interface. The MAC address consists of 6-byte
hex number. The first 3 bytes are a Vendor ID controlled and assigned by IEEE. The last 3 bytes are
controlled and assigned by the manufacturers of network interface (no duplication of MAC address).
Therefore, MAC address is a unique physical address in the world. Ethernet sends and receives frames
on the basis of MAC address.
