DHCP

(Dynamic Host Configuration Protocol) The automatic assigning of IP addresses to client machines logging into an IP network. The same address, although technically temporary, may remain with a machine indefinitely unless a conflict arises with other devices on the network.

The DHCP software, which resides in the router or a server, eliminates the need to manually assign permanent "static" IP addresses to devices. In a home network, the DHCP is typically in the wireless router. See DHCPv6, IP network, static IP address, IP address, DDNS, APIPA and link-local address.

To maximize the unpredictability, we must increase the randomness of IP address assignment. We can separate the IP time interval into two parts ([T.sub.1] and [T.sub.2]).

Infrastructure based IP address assignment solutions do not suffice the need for auto-configuration.
Moreover the built-in Active Devices database keeps the history of IP address assignment to individual devices."
According to Infoblox, its IPAM platform reduces network downtime by simplifying IP address management, increasing the reliability of domain name system (DNS) and IP address assignment (DHCP) services, and automating error-prone network infrastructure-related tasks.
UK-based international commercial law firm Stephenson Harwood is now using Infoblox appliances to run internal and external domain name resolution (DNS), IP address assignment (DHCP) and IP address management (IPAM), the provider of platforms for core network services announced on Monday.
DHCP and DNS network services provide automated IP address assignment and host name lookup services, respectively, and are critical to providing efficient and easy-to-use converged services.
This client software enables user-level authentication, virtual IP address assignment, NAT traversal, and remote policy update and administration.
To gain access to the Internet using IPv4, one must either manually set the IP address, network mask and default gateway or connect through a Dynamic Host Control Protocol (DHCP) server, which allows for automated IP address assignment. While IPv6 does allow manual configurations, it can be handled automatically with no reliance on outside systems using its "Stateless Address Autoconfiguration Protocol." This is accomplished by setting the right-most 64-bits of the IPv6 address to be the host's Interface ID, which is based on the system's unique 48-bit Media Access Control (MAC) address on its Ethernet device.
-- Support for the Dynamic Host Configuration Protocol (DHCP), a dynamic IP address assignment system that simplifies network administration by eliminating the need to assign a unique IP address to every computer on the network; and DNS Proxy, a standard that simplifies configuration by handling translation of domain names into the corresponding IP addresses.
Plug & Play features designed to get users connected quickly and reduce service costs include Dynamic IP Address Assignment with a built-in DHCP Server.
