Understanding name resolution with Domain Name System (DNS)

- In this section, we're going to talk about name resolution.…Name resolution is the process of converting…a name into an IP address.…Computers all over the world have IP addresses,…and when those machines talk to one another,…they base that communication on the IP addresss.…However, me as a human being,…I don't want to have to remember hundreds of IP addresses.…I would rather remember names, such as,…www.google.com.…Google.com corresponds to a particular IP address,…and the process of determining what IP address…is signified by a particular name is called name resolution.…

The most popular and most common name resolution…technique currently used is called…the domain name system or DNS.…DSN is a distributed system.…It would be impossible for one server…to contain a record of every IP address…and every name on the internet.…Therefore, DNS has to be distributed.…Different servers contain different list of addresses,…and when one server needs an address…that isn't on the current server,…it can freely communicate with other DNS…
