The web would not work at all without DNS servers. They are responsible for translating domain names into IP addresses. Then computers use those IP addresses to locate and connect to web servers, and send users to the right websites.
Can internet exist without DNS?
The Domain Name System (DNS) is a hierarchical naming system that allows communication across devices on a network. Most commonly, it translates human-readable domain names (like bluecatnetworks.com) to computer-friendly Internet Protocol (IP) addresses (like 104.239. 197.100).
What happens if DNS does not work?

What is the purpose of DNS in a network?
DNS servers convert URLs and domain names into IP addresses that computers can understand and use. They translate what a user types into a browser into something the machine can use to find a webpage. This process of translation and lookup is called DNS resolution.
Where is DNS located?
These servers reside in your ISP’s data centers, and they handle requests as follows: If it has the domain name and IP address in its database, it resolves the name itself. If it doesn’t have the domain name and IP address in its database, it contacts another DNS server on the internet.
Is changing DNS safe?
Switching from your current DNS server to another one is very safe and will never harm your computer or device. However, ensure you are changing to a known and reliable server, such as Cloudflare or another third-party server that does not sell your data.
Can I create my own DNS server?
There are 2 main types of DNS servers you can run: if you own a domain, you can run an authoritative nameserver for that domain. if you have a computer (or a company with lots of computers), you can run a resolver that’s resolves DNS for those computers.
Do browsers have DNS?
Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device.

What is DHCP How does it make the network admins life easier?
What is DHCP and how does it work? DHCP is an under-the-covers mechanism that automates the assignment of IP addresses to fixed and mobile hosts that are connected wired or wirelessly. When a device wants access to a network that’s using DHCP, it sends a request for an IP address that is picked up by a DHCP server.

How many DNS servers are there?
Root name server overview In total, there are 13 main DNS root servers, each of which is named with the letters ‘A’ to ‘M’. They all have a IPv4 address and most have an IPv6 address. Managing the root server is ICANN’s responsibility (Internet Corporation for Assigned Names and Numbers).
What is difference between DNS and DHCP?
Domain Name System (DNS) is an Internet service that translates domain names (e.g., its.umich.edu) into IP addresses. Dynamic Host Configuration Protocol (DHCP) is a protocol for automatically assigning IP addresses and other configurations to devices when they connect to a network.
Does DNS Affect Internet connection?
Although DNS is not directly related to your Internet speed, it can influence how fast an individual webpage appears on your computer. Once a connection has been established though, it should not affect download speeds. If you want to amend your router’s DNS servers however, this can help improve your overall speed.

How do I know if I have DNS issues?
Run ipconfig /all at a command prompt, and verify the IP address, subnet mask, and default gateway. Check whether the DNS server is authoritative for the name that is being looked up. If so, see Checking for problems with authoritative data.
What DNS server should I use?
Answer: Public DNS systems such as OpenDNS, Cloudflare, or Google DNS are better than the servers maintained by internet service providers. You should use public DNS servers as they offer maximum uptime, faster speeds, and increased security.
