How would you describe the DHCP leasing process?
FROM MSDNDHCP Lease ProcessA DHCP-enabled client obtains a lease for an IP address from a DHCP server. Before the lease expires, the DHCP server must renew the lease for the client or the client must obtain a new lease. Leases are retained in the DHCP server database approximately one day after expiration. This grace period protects a client's lease in case the client and server are in different time zones, their internal clocks are not synchronized, or the client is off the network when the lease expires.The DHCP lease process is a process that occurs when a computer which is a DHCP client initially boots up on the network, to provide an IP address and any additional TCP/IP configuration parameters to these clients.The terminology and concepts used when discussing DHCP leasing or the DHCP lease process is summarized below:DHCP lease: This is the amount of time for which a DHCP client is allowed to make use of a specific IP addresses. The default setting for the DHCP lease is 8 days.DHCP lease process: The process which occurs when the client initially boots up on the network. The DHCP lease process enables DHCP clients to automatically obtain IP addresses from a DHCP server.DHCP Discovery Broadcast message: This is a message sent over the network by a client computer that wants to obtain an IP address from a DHCP server.DHCP Offer message: This is message sent by DHCP servers that serves as a reply to a Discovery Broadcast message.DHCP Request Broadcast message: This message indicates that the client accepted an IP address offer from the first DHCP server which responded to it. The client broadcasts this particular message so that all the other DHCP servers that offered addresses to the client can withdraw their IP addresses.DHCP Acknowledge message: This message is sent by the DHCP server to the DHCP client, and is the process whereby which the IP address lease is assigned to the client.Unlimited lease duration: If you do not want the IP address assigned for a particular client to expire, you assign an unlimited lease duration.DHCP scopes: A scope can be defined as a set of IP addresses which the DHCP server can allocate or assign to DHCP clients. A scope contains specific configuration information for clients that have IP addresses which are within a particular scope. Scope information for each DHCP server is specific to that particular DHCP server only, and is not shared between DHCP servers. During the DHCP lease process, the DHCP scopes configured for a DHCP server is used to provide a DHCP client with an IP address.You can configure different lease duration settings for each DHCP scope.The lease duration rules which should be implemented when you determine the lease duration time for the scope of each of your subnets are:Use a shorter lease duration time if you have numerous mobile users, and if you are working in an environment that constantly has configuration changes.Use a longer lease duration time if the following statements are true:There are no mobile computersThe environment does not continually experience configuration changesIncrease the default setting of 8 days if the number of IP addresses for each subnet is by far greater than the number of DHCP devices within your environment.Use a shorter lease duration period if you have a limited number of IP addresses for each subnet, and you are near to meeting limit.Understanding the DHCP Lease ProcessThe DHCP lease process is a four-step process that occurs when a DHCP client initially boots up on the network. The DHCP process remains unchanged since its initial introduction with Windows NT 4.0. During the DHCP lease process, negotiation for an IP address occurs between a DHCP server and a client that needs to obtain an IP address. In a TCP/IP based network, to uniquely identify computers on the network, each computer must have a unique IP address. To communicate on the Internet and private TCP/IP network, all hosts defined on the network must have IP addresses. The 32-bit IP address identifies a particular host on the network. With DHCP, the system assigns IP addresses to clients, which in turn leads to less incorrect configurations of IP addresses. This is mainly due to IP configuration information being entered at one location, and the server distributing this information to clients. Duplicated IP addresses are also prevented.The DHCP lease process that occurs between the DHCP server and client is a simple process. The negotiation process for an IP address consists of four messages sent between the DHCP server and the DHCP client.Two messages from the clientTwo messages from the DHCP serverWhen the server assigns IP addresses to DHCP clients, it starts allocating addresses commencing from the bottom of its scope range, and starts moving to the top of its scope range.All unused addresses have to be used before the DHCP server:Allocates a previously used IP addresses to a new DHCP client. The DHCP server first assigns IP addresses that have not been used for the longest amount of time prior to assigning other previously used IP addresses.Allocates an expired IP addresses to a new DHCP clientDuring the four-step DHCP lease process, the events that occur are defined by the types of DHCP messages which are exchanged between the DHCP server and DHCP client:DHCPDISCOVER message: This message is used to request an IP address lease from a DHCP server. The message is sent when the client boots up on the network. The message is sent as a broadcast packet over the network, requesting for a DHCP server to respond to itDHCPOFFER message: This message is a response to a DHCPDISCOVER message, and is sent by one or numerous DHCP servers.DHCPREQUEST message: The client sends the initial DHCP server which responded to its request a DHCP Request message. The message basically indicates that the client is requesting the particular IP address for lease. The other DHCP servers who offered addresses withdraw those addresses at this point.DHCPACK message: The DHCP Acknowledge message is sent by the DHCP server to the DHCP client and is the process whereby which the DHCP server assigns the IP address lease to the DHCP client.The four steps involved in the DHCP lease process is often called DORA:DiscoverOfferRequestAcknowledge
What is SAP an acronym of in technology?
SAP is a technology for provision of Enterprise Resource Planning (ERP) solutions for specific industries. SAP also refers to the German software company that owns the technology.
How many IP addresses must you obtain from your ISP in order for all five clients in your office to be able to access servers on the Internet?
One - and it doesn't necessarily have to be a public IP address. Then you share this single IP address over the entire network, with NAT.
What technology automatically assigns IPA addresses to clients?
DHCP (Dynamic Host Configuration Protocol) assigns IP Addresses & other DHCP Options to Clients.
When an integrated router is configured to be a DHCP server for the local network it automatically does what?
Assigns addresses and configures clients for network access.
Configure the dhcp clients to retrieve dynamic ip addresses from dhcp server?
Just make sure you set the clients to "automatically receive IP Addresses".
What is the best description of a dhcp?
it assigns IP address to clients
What is the correct way to write this sentence Please verify our clients client's or clients addresses and phone numbers when taking orders?
Please verify our clients' addresses and phone numbers when taking orders.

Can push technology be applied to thin clients?
Yes.
What do you initially need to configure on a DHCP server in order to give out IP addresses to clients?
a scope
What dhcp option should you modify to make sure you are not wasting addresses that were used by clients who've completed a class and no longer need them?
To keep from wasting addresses you need to use a short lease time so that the IP addresses are reused after the class. Set the lease time interval to a value that is shorter than the class period.
What is the potential benefit of using a DHCP server within a network?
The benefit would be to automatically assign network addresses to clients that need them to work on a local area network. Without DHCP you would have to assign each device an address, subnet mask, and default gateway, plus DNS and WINS server addresses, which can be time consuming and error prone. With DHCP, most of those problems disappear.
