The DHCP server (Dynamic Host Configuration Protocol)

What is DHCP?Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (i.e., a scope) configured for a given network.

DHCP assigns an IP address when a system is started, for example:

  1. A user turns on a computer with a DHCP client.
  2. The client computer sends a broadcast request (called a DISCOVER or DHCPDISCOVER), looking for a DHCP server to answer.
  3. The router directs the DISCOVER packet to the correct DHCP server.
  4. The server receives the DISCOVER packet. Based on availability and usage policies set on the server, the server determines an appropriate address (if any) to give to the client. The server then temporarily reserves that address for the client and sends back to the client an OFFER (or DHCPOFFER) packet, with that address information. The server also configures the client's DNS servers, WINS servers, NTP servers, and sometimes other services as well.
  5. The client sends a REQUEST (or DHCPREQUEST) packet, letting the server know that it intends to use the address.
  6. The server sends an ACK (or DHCPACK) packet, confirming that the client has a been given a lease on the address for a server-specified period of time.

How dhcp service may be provided?

DHCP (Dynamic Host Configuration Protocol) service can be provided through a dedicated DHCP server that assigns IP addresses and network configuration settings to devices on a network automatically. This server can be software-based, running on a server operating system, or hardware-based, integrated into network routers or switches. Additionally, DHCP can be implemented in a failover setup for redundancy, ensuring continuous service availability. The server communicates with clients using broadcast messages to dynamically allocate IP addresses from a predefined range.


What mode of networking uses a DHCP server?

The mode of networking that uses a DHCP (Dynamic Host Configuration Protocol) server is typically a client-server architecture within local area networks (LANs). In this setup, the DHCP server automatically assigns IP addresses and other network configuration settings to devices (clients) on the network, allowing them to communicate effectively without manual configuration. This simplifies network management and ensures that IP address conflicts are minimized.


HOW DO you CONFigure your router to assign ip addresses to network devices?

Read the section of the manual concerning enabling the router to be a DHCP server. DHCP is the magic that assigns IP numbers.


What type of server does a window client use to resolve host names to IP addresses?

Strictly speaking, Windows clients will use a DNS server to resolve host names to IP addresses. In a Windows environment, the DNS server is almost always a Domain Controller as well (Active Directory Integrated DNS). Windows also has another naming system called NETBIOS. Clients will use a WINS server to resolve NETBIOS names (do not confuse with host names) to IP addresses. Short answer: DNS


Who assigns IP addresses to computers?

In North America, the American Registry for Internet Numbers (ARIN) is the organization that allocates IP Addresses for Internet Service Providers (ISP).


What is DHCPINFORM?

DHCPInform is a DHCP message used by DHCP clients to obtain DHCP options. While PPP remote access clients do not use DHCP to obtain IP addresses for the remote access connection, Windows 2000 and Windows 98 remote access clients use the DHCPInform message to obtain DNS server IP addresses, WINS server IP addresses, and a DNS domain name. The DHCPInform message is sent after the IPCP negotiation is concluded. The DHCPInform message received by the remote access server is then forwarded to a DHCP server. The remote access server forwards DHCPInform messages only if it has been configured with the DHCP Relay Agent..

What are the components of the DHCP?

The components of DHCP (Dynamic Host Configuration Protocol) include the DHCP server, which assigns IP addresses and configuration settings; the DHCP client, which requests and receives these settings; and the DHCP relay agent, which facilitates communication between clients and servers on different subnets. Additionally, the protocol relies on a database to track assigned IP addresses and lease times, ensuring efficient management of IP address allocation.
