DHCP

Dynamic Host Configuration Protocol was derived from the Internet standard Bootstrap Protocol (BOOTP) (RFCs 951 and 1084), which allowed dynamic assignment of IP addresses (as well as remote-booting of diskless work stations). In addition to supporting dynamic assignment of IP addresses, DHCP supplies all configuration data required by TCP/IP, plus additional data required for specific servers.
As noted, this makes life easier for the network administrator, who can now manually configure just one machine-the DHCP server. Whenever a new host is plugged into the network segment that is served by the DHCP server (or an existing host is turned back on), the machine asks for a unique IP address, and the DHCP server assigns it one from the pool of available IP addresses.
Advanced Network Monitor can check DHCP servers. It works as described above: connects to the DHCP server and asks for a unique IP address. If the DHCP server returns a correct IP address then the DHCP server protocol is working correctly.

You need to enter the following parameters:
  • Server address - Address of the DHCP server. It may be a domain name, URL or IP address. If you enter an IP address Advanced Network Monitor will try to resolve it.
  • Port - Port of the POP3 server. The default TCP/IP port for the DHCP protocol is port 135.

    Advanced Network Monitor tries to connect to the specified DCHP server and receive a proper IP address. If the program receives an IP address from the DCHP server correctly then the DHCP server is marked as "Success".
    Otherwise the DCHP server is marked as "Error".
