BENEFITS OF DYNAMIC IP
Network administrators face a host of challenges building and maintaining
their TCP/IP networks. Typically, they must assign IP (internet protocol)
addresses, host names, and other network information at individual computers.
This forces them to track changes every time a computer is either added,
removed or relocated in the network. Users or administrators must also
manually configure computers for network access. These tasks are
time-consuming, error prone, and can disrupt network operations. IBM has
addressed these challenges with a new networking technology called Dynamic IP.
IBM is introducing Dynamic IP in OS/2 Warp Server. Dynamic IP implements a
true TCP/IP "plug-and-go" network solution, greatly simplifying both IP
network access and IP network administration. Furthermore, Dynamic IP is
well-suited for networking mobile hosts and is fully compatible and
interoperable with existing IP network hosts and routers.
Dynamic IP is the integration of the Dynamic Host Configuration Protocol
(DHCP) and Dynamic Domain Naming System (DDNS). Both DHCP and Dynamic DNS are
new features to OS/2 Warp, and Dynamic DNS is a first in the industry.
DHCP and DDNS are complementary open networking standards developed by the
IETF (Internet Engineering Task Force). Each protocol implements half of the
TCP/IP "plug-and-go" network solution. The DHCP protocol centralizes and
automates the configuration of IP hosts, including IP addresses, while the
Dynamic DNS protocols automatically record the association between IP hosts
and their DHCP-assigned addresses.
Using DHCP and DDNS, a host automatically configures itself for network access
wherever it "plugs-in" to the IP network. That host can then be located and
accessed using its permanent, unique DNS host name. Mobile hosts, for example,
can therefore freely move about a network without knowledge of the local IP
network addresses or services and without end-user or administrator
intervention.
The OS/2 Warp Server software package includes a Dynamic IP client, a DHCP
server, and a Dynamic DNS Server. The Dynamic IP client consists of both a
DHCP and a Dynamic DNS client component. The DHCP client may be configured to
operate as a simple DHCP client or as a Dynamic IP client, integrating Dynamic
DNS client services with the DHCP client. The Dynamic DNS server is a superset
of the industry-standard "BIND" DNS server and may be configured to operate as
a traditional static DNS server or a new Dynamic DNS server, or both.
