... Address Resolution Protocol (ARP)
According to computerhope.com, ARP is short for Address Resolution Protocol. ARP is a protocol used with the IP protocol for mapping a 32-bit Internet Protocol address to a MAC address that is recognized in the local network specified in RFC 826. Once recognized the server or networking device returns a response containing the required address. ... For example, you would use arp –s to change the IP address and associate it with a physical address. ... 212 00-aa-00-62-c6-09, will change the physical address of 00-aa-00-62-c6-09 to IP address 157. ... The term ARP refers to the process of finding an address of a computer in a network. The address is found by using a protocol in which a piece of information is sent by a client process executing on the local computer to a server process executing on a remote computer. The information received by the server allows the server to provide the required address. The ARP is completed when the client receives a response from the server containing the required address. ... Packet InterNet Groper (PING)
According to Webopedia, the acronym “ping” is short for Packet InterNet Groper, and is a utility used to verify if a network data packet is capable of being distributed to an address without errors. ...
Ping is a basic Internet program that lets you verify that a particular IP address exists and can accept requests. ...

Using ping, you can also see the number form of the IP address. ... Ping operates by sending a packet to a designated address and waiting for a response. ... DHCP vesus DNS
Dynamic Host Configuration Protocol (DHCP)
Dynamic Host Configuration Protocol (DHCP), a networking protocol, provides a means to allocate IP addresses dynamically to computers on a local area network (LAN). A network administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address automatically from the DHCP server when that client computer starts up. ... It is a protocol for automating the configuration of computers that use TCP/IP).
In networking, a network protocol is the specification of a set of rules for a particular type of communication.
In addition to the IP address, a DHCP server can provide other information like DNS server addresses, a DNS domain or a gateway IP address. But despite a broad level of support for the protocol, surprisingly few DHCP installations go beyond its most basic features. Most DHCP products and their users treat it as if it were nothing more than an advanced address-assignment protocol, and few users truly leverage the host configuration aspects that define DHCPs true power. ... The most significant piece of information distributed in this manner is the IP address
DHCP run over UDP, utilizing ports 67 and 68. The User Datagram Protocol (UDP) is a minimal message-oriented transport layer protocol. ... (For this reason UDP is sometimes expanded to "Unreliable Datagram Protocol"). ... When a computer in this setup sends a request to the Internet, its private IP address is transmitted to the Internet. ... This is done by using the Dynamic Host Configuration Protocol (DHCP). ... You can also disable the automatic addressing service and statically assign an IP Address to each computer. ... Every computer on the Internet has a unique address - just like a telephone number - which is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol"). ... The DNS makes using the Internet easier by allowing a familiar string of letters (the "domain name") to be used instead of the IP address. ... Information about who is responsible for domain names is publicly available to allow rapid resolution of technical problems and to permit enforcement of consumer protection, trademark, and other laws. ... You can only make connections by providing the IP address of the computer you wanted to establish a link with. For example, a typical IP address might be 216. ... coms IP address. ... So does this e-mail address: brain@howstuffworks. ... Every time you use a domain name, you use the Internets DNS servers to translate the human-readable domain name into the machine-readable IP address. ... It specifies the name of a specific machine (with a specific IP address) in a domain. ... It can answer the request with an IP address because it already knows the IP address for the requested domain. ... It can contact another DNS server and try to find the IP address for the name requested. ...
