Dynamic Host Configuration Protocol
In order to configure PCs automatically, centralized and uniformly in a TCP/IP network, a dynamic assignment
of IP addresses is used. DHCP is used. The system administrator determines how the IP addresses are to be
assigned and specifies the time lapse over which they are assigned. DHCP is defined in the Internet standards
RFC 2131 (03/97) and RFC 2241 (11/97).
For SIPROTEC 5, a device can also be assigned an IP address via DIGSI via DHCP.
