About Domain Name System (DNS)

DNS

Domain Name System (DNS) is the Internet’s mechanism for linking all the host names and IP addresses on the Internet. In other words, DNS is a distributed and linked system of resolving names to IP addresses. The DNS system is similar to an environment in which all telephone information operators are linked together so that your request can get passed to the appropriate operator.

All the URLs that you need to get resolution for on the Internet are in a DNS database somewhere. A DNS database administrator has entered the name and IP address into the database. When you use a browser and request Who Is for www. find-ip-address.org, www refers to a service, and find-ip-address.org to the host name. The .org refers to the portion of the domain space where this host is found. A URL is a combination of the service, host name, and domain where the host can be found.

Multicasting Additional Notes that You have to Read

To understand what we are going to talk about, you must be familiar with how MAC addresses are structured and how they work. The MAC Addresses page is available to help you learn more about them..

A multicast is similar to a broadcast in the sense that its target is a number of machines on a network, but not all. Where a broadcast is directed to all hosts on the network, a multicast is directed to a group of hosts. The hosts can choose whether they wish to participate in the multicast group (often done with the Internet Group Management Protocol), whereas in a broadcast, all hosts are part of the broadcast group whether they like it or not :).
