The OUI. C. The device identifier. D. The physical address. - B. The OUI. - MAC ADDRESSES The first 24 bits are known as the OUI (Organizationally Unique Identifier) which identifies the NICs manufacturer. A manufacturers OUI is assigned by the IEEE.

IP address An IP address is a unique number assigned to every device connected to a network that uses the Internet Protocol for communication. Each IP address identifies the device’s host network and the location of the device on the host network.

A) It is a unique identifier burned into the NIC when it is manufactured. B) It is a unique dotted decimal number assigned to every network node. C) It is a number shared by all computers on the same network. D) It is a number assigned only to routers identifying their priority ratings.

What is a MAC Address and How Do I Find It? | TechTarget

A MAC address (media access control address) is a 12-digit hexadecimal number assigned to each device connected to the network. Primarily specified as a unique identifier during device manufacturing the MAC address is often found on a devices network interface card ( NIC ).

Data traversing the Internet is divided into smaller pieces called packets. IP information is attached to each packet and this information helps routers to send packet... See full list on cloudflare.com In networking a protocolis a standardized way of doing certain actions and formatting data so that two or more devices are able to communicate with and understand each other. To understand why protocols are necessary consider the process of mailing a letter. On the envelope addresses are written in the following order name street address city... See full list on cloudflare.com An IP address is a unique identifier assigned to a device or domain that connects to the Internet. Each IP address is a series of characters such as 192.168.1.1. Via DNSresolvers which translate human-readable domain names into IP addresses users are able to access websites without memorizing this complex series of characters. Each IP packet w... See full list on cloudflare.com The fourth version of IP (IPv4 for short) was introduced in 1983. However just as there are only so many possible permutations for automobile license plate numbers and they have to be reformatted periodically the supply of available IPv4 addresses has become depleted. IPv6 addresses have many more characters and thus more permutations; however I... See full list on cloudflare.com IP packets are created by adding an IP header to each packet of data before it is sent on its way. An IP header is just a series of bits (ones and zeros) and it records several pieces of information about the packet including the sending and receiving IP address. IP headers also report 1. Header length 2. Packet length 3. Time to live (TTL) or ... See full list on cloudflare.com The Internet is made up of interconnected large networks that are each responsible for certain blocks of IP addresses; these large networks are known as autonomous systems (AS). A variety of routing protocols including BGP help route packets across ASes based on their destination IP addresses. Routers have routing tables that indicate which ASes ... See full list on cloudflare.com The Transmission Control Protocol (TCP) is a transport protocol meaning it dictates the way data is sent and received. A TCP header is included in the data portion of each packet that uses TCP/IP. Before transmitting data TCP opens a connection with the recipient. TCP ensures that all packets arrive in order once transmission begins. Via TCP the... See full list on cloudflare.com The User Datagram Protocol or UDP is another widely used transport protocol. It is faster than TCP but it is also less reliable. UDP does not make sure all packets are delivered and in order and it does not establish a connection before beginning or receiving transmissions. See full list on cloudflare.com A network switch is an appliance that forwards data packets within a local area network (LAN). Most network switches operate at layer 2 the data link layer not layer 3 the network layer and therefore use MAC addresses to forward packets not IP addresses.
