What device determines the point where one local network ends and another local network begin?
A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination.
What type of network address space allows for nodes?
Non-routable address space
Non-routable address space allows for nodes to communicate with each other on same network.
How many possible host IDs Do you always lose per network?
How many possible host IDs do you always lose per network? 2; You always lose two host IDs per network. So, if a /24 network has 2^8 or 256 potential hosts, you really only have 256 – 2 = 254 available IPs to assign.
What protocol is used to find the hardware address of a node with a certain IP?
ARP
ARP is a simple query–response packet protocol used to match workstations hardware addresses to IP addresses. In other words, ARP is the protocol used to identify nodes in a LAN. ARP is described in RFC 826.
What device determines the point where one local network?
A router is a physical or virtual appliance that passes information between two or more packet-switched computer networks. A router inspects a given data packet’s destination Internet Protocol address (IP address), calculates the best way for it to reach its destination and then forwards it accordingly.
What does ARP stand for and what does it do?
Address Resolution Protocol
Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).
What is a node in LAN?
LANs and wide area networks. These nodes are devices that perform a specific function. Each one must have a Media Access Control address for each network interface card. Examples include modems with Ethernet interfaces, wireless LAN access points and computers.
How many IPS is a Class C?
IP address classes
| Class | Leading bits | Addresses per network |
|---|---|---|
| Class A | 0 | 16,777,216 (224) |
| Class B | 10 | 65,536 (216) |
| Class C | 110 | 256 (28) |
| Class D (multicast) | 1110 | not defined |
What is the number of network and host IDs in a Class C network?
Class C networks have 21 bits for the Network ID (Bits 22, 23, 24 are set and can’t be changed) and 8 bits for the Host ID, that means you can have up to ‘2 to the power of 21’ = 2,097,152 Networks and ‘2 to the power of 8’ = 256 Hosts in each Network, of which 2 cannot be used because one is the Network Address and …
What is ARP protocol in networking?
Address Resolution Protocol (ARP) is a protocol or procedure that connects an ever-changing Internet Protocol (IP) address to a fixed physical machine address, also known as a media access control (MAC) address, in a local-area network (LAN).
What protocol is used to discover the hardware address of a node with a certain IP address subnet mask?
ARP table – ARP is a protocol used to discover the hardware address of a node with a certain IP address.
