Domain Name Service (DNS) is the standard naming service in TCP/IP-based networks. It converts IP addresses, such as 192.168.1.1, to human-readable domain names, such as myserver.example.com, and it reverses the conversion process as required.
The Dynamic Host Configuration Protocol (DHCP) assigns IP addresses and configuration parameters to hosts and network devices.
OES 2015 SP1 includes a ported version of the NetWare DNS service, and an eDirectory integration with ISC DHCP as explained in the sections that follow.
As you plan to upgrade from NetWare to OES 2015 SP1, consider the following differences between DNS on NetWare and OES 2015 SP1:
