What does ARPA stand for?

ARP stands for Address Resolution Protocol, a network layer protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.

When will get apipa address in dhcp client?

A DHCP client will receive an Automatic Private IP Addressing (APIPA) address when it fails to obtain an IP address from a DHCP server after several attempts. This typically happens when there is no DHCP server available on the network or if the server is unreachable. APIPA assigns an IP address in the 169.254.0.1 to 169.254.255.254 range, allowing for local communication on the same subnet.

What is the protocol used at the network layer to obtain an IP address?

At the network layer, the protocol commonly used to obtain an IP address is the Dynamic Host Configuration Protocol (DHCP). DHCP allows devices to request and receive an IP address and other network configuration parameters automatically from a DHCP server. This process involves a series of messages exchanged between the client and server, including DHCP Discover, Offer, Request, and Acknowledgment. By using DHCP, devices can join a network with minimal manual configuration.

What does acquiring network address means?

The device is looking for a DHCP server to obtain a DHCP address.

How would you obtain the MAC address from a machine?

It depends on the machine. However, the MAC address is usually found in the network interface properties.

What is dhcp accept?

DHCP Accept is not a standard term in networking, but it may refer to the process where a DHCP client accepts an IP address and configuration parameters assigned by a DHCP server. During DHCP communication, after the server offers an IP address, the client sends a DHCP Request to accept that offer, and the server responds with a DHCP Ack to confirm the lease. This process enables devices to automatically obtain network settings without manual configuration.

What is an arp request packet for?

ARP stands for Address Resolution Protocol. This is IP's way of requesting a MAC address (or hardware address) from a host located at a certain IP address. In order for a host on a network to send a unicast packet across the network, it must know both the source and destination MAC addresses. ARP is used to obtain a MAC address similar to the way DNS is used to obtain an IP address from a domain name (www.anydomain.com).

What allows a host to obtain an IP address dynamically when it connects to the network?

Its very simple one when the host connects to the network it is DHCP dynamic host control protocol which is used to assign the IP address to the address seeking hosts in the network. it simply take any IP address from the pool of IP address and assign on to the host on lease based after using this must be sent back to the DHCP server ( your router in most cases )

How do you get a Network Rail Card?

If you are wishing to purchase a Network Rail card you will first need to obtain an application form. This form can be either downloaded from the internet or obtained from your local staffed railway station. Once you have filled in the form, you return it to the ticket office of your local station where you will be able to complete the purchase.

Describe the steps taken by the client and DHCP server in order to obtain an IP address?

Firstly, a DHCP server is needed which distributes the IP addresses. This machine will serve as a base for all DHCP requests and must also have a fixed IP address. Therefore, on a network there can only be one machine with a fixed IP address, the DHCP server.The basic communication system is BOOTP (with UDP frame). When a machine is turned on, it has no information on its network configuration, and there is nothing special that the user needs to do to find an IP address. In order to do this, the technique used is the broadcast: to find and talk with a DHCP server, the machine will simply send a special broadcast packet (broadcast on 255.255.255.255 with other information such as the type of request, the connection ports, etc.) over the local network. When the DHCP receives the broadcast packet, it will send back another broadcast packet (do not forget that the client does not obviously have the IP address and that therefore cannot be connected to directly) containing all the information required for the client.It could be believed that one single packet is enough for the protocol to work. In fact, there are several types of DHCP packets likely to be issued either by the client for the server(s), or by the servers to a client:DHCPDISCOVER (to locate available DHCP servers)DHCPOFFER (server response to a DHCPDISCOVER packet, which contains the initial parameters)DHCPREQUEST (varied request from the client for example to extend its lease)DHCPACK (server response which contains the parameters and IP address of the client)DHCPNAK (server response to indicate to the client that its lease has expired or if the client announces a bad network configuration)DHCPDECLINE (the client announces to the server that the address is already in use)DHCPRELEASE (the client releases its IP address)DHCPINFORM (the client requests local parameters, it already has its IP address)The first packet issued by the client is a DHCPDISCOVER type packet. The server responds with a DHCPOFFER packet, particularly in order to submit an IP address to the client. The client establishes its configuration and then makes a DHCPREQUEST to validate its IP address (a broadcast request since DHCPOFFER does not contain the IP address). The server simply responds with a DHCPACK with the IP address for confirmation of the allocation. Normally, this is enough for the client to obtain an effective network configuration, but it can be longer or shorter according to whether the client accepts the IP address or not.Hope this will help you to understand DHCP.Regards,Jaydeep.Gatlewar@gmail.com

What is the gateway on my computer?

The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world. If the default gateway is not configured correctly, the usual symptoms are that your computer can connect within the local network, but it can't connect to the outside.You have to obtain the address which you should assign as the default gateway from your network administrator, or from your ISP.The default gateway refers to the "next-hop address"; the server or router your computer has to send packets to, to connect with the outside world.
