6.3 DHCP Service
DHCP (Dynamic Host Configuration Protocol) is a communication protocol used to
distribute IP addresses and other configurations between Client PSs and DHCP server. It
mainly features to enable one computer broadcasts through its own MAC address to
obtain configurations related to IP, Netmask, Default Gateway and DNS. Thus a network
administrator only needs to configure DHCP server, so that Client PC can automatically
obtain IP related configurations through DHCP protocol, saving efforts to configure on
each client PC.DHCP and NAT (transferred Virtual IP to legal IP) are not directly related.
Please make sure not to error.
DHCP servers are all easy to use and set up. Therefore, if your PC fails to obtain an IP
address, the problem generally originates in such PC devices as network cabling, NIC of
PCs, HUB, switches, NT servers, printer servers, or / and interweaving of internal and
external networks.
