It's an unsung hero that allows us to use the internet in the simplest way possible. Without DNS, our connected lives would look very different. DNS will take our domain name, and translate, or resolve it, into an IP address. Let's say you want to go to your favourite website, so you type, 🤍certbros.com. Remember, web servers do not work with domain names, so your computer needs to translate this into an IP address. The first thing it does is check its local cache both on the computer and the browser. There’s also a local configuration file that's checked. If there are no cache entries, your computer will send a query to something called a DNS recursive resolver asking for the IP address of certbros.com. Once the DNS resolver receives your query, it checks its cache. If it can’t find an entry for certbros.com, it will send a request to another server, this is called a ROOT server. The root server will then refer us to the top-level domain server (TLD) for .com. A TLD server is a server that contains information for domains with a specific extension. For example .com .org .net etc The TLD server will then refer us to the authoritative nameserver. The authoritative nameservers will have a record for Certbros.com and it will return the IP address to our DNS Resolver which will then send it back to our computer. Out computer will now be able to contact the webserver using the newly discovered IP address. #ccna #cisco #networking

A look at something you've just used, DNS! Note in my demo I request just the child part of the FQDN that the name server is authoritative for to avoid any cached entries return the final resolution too soon but as I said in the whiteboard the full FQDN is asked each time and you just get referred to the next nameserver down. 👂 I have manually updated the captions to be as accurate as possible. Enable the subtitles and from there you can translate to your native language via the auto-translate feature in settings! 🤍 for a demo of using this feature. 🔎 Looking for content on a particular topic?

Learn about DNS, DNS Server or DNS name server, DNS lookup, what is dns server and how it works, how DNS server or Domain Name System works. DNS or Domain Name System translates domain names to their IP addresses so that browsers can load the requested website. Servers are computers storing HTML files, images, sounds, videos or any other file types. Servers that work together to provide IP address of the requested website to the web browser are called DNS servers. Notes : 🤍 Facebook : 🤍 DNS resolver connects the web browser of our computer to the DNS name servers. There are 13 sets of root name servers, logically named as Letter.root-servers.net, where Letter ranges from ‘a’ to ‘m’, and are operated by 12 different organizations. Each set has a number of servers placed around the world. TLD name server stores the information of all domain names sharing a common domain extension. Authoritative name server is the last server in the Domain Name System. It stores the IP address of the requested website When we purchase a domain name from a registrar, Registry updates the authoritative name server for the purchased domain in the TLD name server. So, when TLD name server receives a DNS query, it forwards DNS resolver to the correct authoritative name server. DNS servers eliminate the need for humans to memorize these complex IP addresses. The only thing we need to memorize is the domain names which are easier to remember. #TechTerms Must learn: DHCP Protocol : 🤍 ARP Protocol : 🤍 DNS Explained : 🤍 OSI Model : 🤍 IP Address : 🤍 NIC : 🤍 Network Protocol : 🤍 Network Topology: 🤍 Network Router : 🤍 Network devices : 🤍 Firewall : 🤍 Firewall types : 🤍 Firewall vs : 🤍 Firewall working : 🤍 Firewall limits : 🤍 Domain name : 🤍 LAN cable : 🤍 Hostname : 🤍

Your home internet has a privacy problem! DNS, or Domain Name System, is the lookup system responsible for converting human-readable domain names like google.com into IP addresses, which is the format that computers need to communicate with each other. But in this process, a LOT of data is leaked about your internet activities, and collected by all kinds of entities like ISPs and government organizations. In this video, we’ll explain how DNS works, and how to set up your DNS to make your internet browsing far more private. 00:00 Intro 00:37 What is DNS? 01:09 How Does DNS Work? 07:02 Privacy Concerns 09:07 How to Protect DNS Queries 10:14 Quad9 13:50 How to Switch to Quad9 15:33 Conclusion DNS privacy is a critical part of your home network security. Take 5 minutes to create more private DNS settings. Special thanks to John Todd, Brent Cowing, Kieran Mesquita, and Alex Wied for their help with this video!
