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?
We don’t need to know the IP addresses for our favorite sites because the DNS stores them all for us in a directory like database. It would be too difficult for us to remember each IP address for each individual website. What feature of DNS and IP allow the internet to scale?
Why don’t we all maintain our own DNS?
Why do we need a Domain Name System? Domain Name System allows users to have the same url or consistent domain name while IP addresses change frequently. We need DNS because without it users would need to keep on checking the IP addresses of others and of themselves to send messages or view sites.
Why do we need an IP address?
An Internet Protocol address, or IP address is a unique identifier given to every machine in a network. An IP address serves two primary functions. Because an IP address is a unique identifier, it allows computers to send and receive information to and from specific computers in a given network.
How many unique IP addresses can a fixed length using 6 bits?
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?
DNS (Domain Name Server) is mainly used to convert human meaningful name (domain name) to computer meaningful name (IP address) in Internet. It allows you to use internet more easily by allowing you to specify a meaningful name on your web browser instead of using IP address.
What is meant by IP address?
An IP address, or simply an “IP,” is a unique address that identifies a device on the Internet or a local network. It allows a system to be recognized by other systems connected via the Internet protocol. There are two primary types of IP address formats used today — IPv4 and IPv6.
What are 2 benefits of using domain name system?
DNS translates the names of domain into meaningful to humans into binary identifiers that are associated with the equipment of network to locate and address these devices. Advantages: – More Reliable: Delivers messages to the users with zero downtime. – Faster: DNS are connected well at intersections of internet.
Is there one big DNS for the Internet?
Is there one big DNS for the entire Internet? No. There are many DNS servers that individually connect to form the internet.
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.
