NDS replication is similar to time synchronization in that servers must
keep and share accurate information to maintain fault tolerance and
distributed access to the database.
Devices on networks must be uniquely identified so that other devices can find
and use their services. Since

addressing protocols.
Two kinds of addresses identify hosts on the network: hardware or media
access control (MAC) addresses, and software addresses. IPX
MAC address of the Ethernet or token ring network board to identify the host
on the network. Since the MAC and node addresses are the same, there is no
further translation required to identify the host. IP addresses are not the same
as the MAC address of the network board, so IP addresses must be translated
into MAC addresses. Address Resolution Protocol (ARP) translates IP
addresses to MAC addresses on IP networks.
Dynamic Host Control Protocol (DHCP) is an Internet protocol that provides
dynamic distribution of IP addresses to workstations. DHCP helps network
administrators with the task of assigning IP addresses to workstations and
lessens the problems associated with a shortage of IP addresses. There is no
equivalent to DHCP in IPX networks because of the abundance of IPX
addresses and their ability to use the MAC address as the software address.
