An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is connected to a computer network that uses the Internet Protocol for communication. As I understand it, two computers cannot have the same public (external) IP address unless they are connected via the same router. An Internet Protocol (IP) address is essentially a unique identification number for machines connected to any network. An IP address is like a phone number, whereas your computer is like a phone. 3) device don't need to communicate with themselves. There is a standard of communication which is called an Internet Protocol (IP) standard. Harvard architecture has two separate buses for instruction and data.

DHCP , for Dynamic Host Configuration Protocol , is one of the ways that ISPs re-use IP addresses when computers aren’t continuously connected (and even sometimes when they are). Typically, the information includes the … A computer network is a set of computers sharing resources located on or provided by network nodes.The computers use common communication protocols over digital interconnections to communicate with each other. Just as a street address determines where a letter should be delivered, an IP address identifies computers on the Internet. I understand if two IP addresses are AND'd with a subnet mask if the result is the same then they are on the same network. They may be dynamically assigned (they can change automatically) or statically assigned (they're intended not to change, and must be changed manually). But if you are not sure about the IP address then you should use the above details. For example, to communicate between two computers on remote networks it may be necessary to pass through several routers. 192.168.1.64 is the IPv4 address the physical interface with MAC 00:1f:f3:5a:77:9b is using.
