The DNS Service



DNS (Domain Name System) is a service that translates domain names into IP address, which are used by computers to communicate with each other. 

It acts as a directory that links a domain name to an IP address and enables users to access websites, email, and other internet services using a domain name instead of an IP address.

A DNS server is responsible for converting domain names into IP addresses. 

When a user types a domain name into their web browser, the browser first contacts the DNS cache (local) and then a DNS server to look up the corresponding IP address, and then the browser can communicate with the server hosting the website at that IP address. 

The DNS service is divided in a few different types of Servers:

  • Root
  • TLD
  • Non Authoritative

The wiring day (Raul Garcia)

This wednesday we had an special class. Instead of having or usual AWS lections, we had to make lots of Ethernet cables, wich, might sound boring, but sure it wasnt. We started slow, there was more than 2 hours left, and the recess was just around the corner, we only had to make 28 wires, which had to be more than 5 meters long. Only a few cables were made when the recess started, when we came back we kept going with our chore Every single wire had to be made with caution, just a small mistake and all the process had to be started again, which made the work quite stressful. Luckly I didnt make any mistake, and managed to make 4 cables. The last hour of the work was the worst, only then was when we realiced how many of them were missing, so all of us, tired and stressed started to make as many as possible to reach the goal. At the end all of the class managed to make 25 in total, which wasnt 28, but close enough to be ok. At least for me it was a really fun experience, and we will have

Today's class (Raúl García)

 I started my day with AWS class, we had to make diferent virtual machines on amazon web services, so we could put a web page, on which you had to register to see it. I wasn't sure about how to make the "EC2 instances" so I had to watch a YouTube video, I didn't had enought time, but next week we will have more time. Next we had english class, we started with an exam, for me it was easy, so I didn't had any problem there. After that the teacher presented the new project we had to do, on which que have to make a job interview with a teammate in two weeks. I will make the project with Samuel, he is one of my best friends here in puenteuropa, we will do great for sure!
