Question: Why Don’t We Need To Know The IP Addresses For Your Favorite Sites?

Because we have the domain name system (DNS).

It registers friendly names, e.g., google.com that represent IP addresses.

Your computer will consult a DNS service to query the IP address for a domain name you enter, and under-the-hood the connection is made to the IP address.

Why don’t we need to know IP addresses quizlet?

What should I understand from this?! The best way to solve with a unique IP is to just multiply itself by itself. you would use it as an exponent on the number two. example, 6 bits, so you would solve by using the 2^6 which equals 64!

Why do we need a DNS?

What is a DNS address?

Tweet. Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses

What is an Internet Protocol IP address How is it organized hierarchically?

-It is organized hierarchically by each number is represented by bits. IP addresses are 32 bits with 8 bits per part of the address. The system of hierarchy works like this first numbers are usually the country/network, 2nd numbers are region/network, then its subnetwork and finally its the device.

Can you know in advance the path a message will take between you and another computer on the Internet?

Can you know in advance the path a message will take between you and another computer on the Internet? No, because depending on how much traffic there is between other routers the message will take the fastest route possible to the other computer which could change day to day or hour to hour based on the traffic.

Why do computers need to periodically check the DNS for websites you have already visited?

Answer Expert Verified

Computers need to periodically check the DNS for websites you have already visited because the IP address associated with a given URL or domain is not static rather dynamic-changes with time, and it can change over course of time.
