DNS (Domain Name System) are a mechanism with which domain names are translated into IP addresses so that browsers can load the resources of that website and vice versa. This helps us as users, instead of entering the IP of the site, we simply write its domain name, honestly it is easier to enter solvetic.com in a browser than 190.157.8.109, remember that each device that is connected to the network has a unique IP address which is used by other devices for its detection, so that the DNS resolution process allows us to convert a host name into an IP address compatible with the equipment we use..
Important aspects in DNS
When we connect to a website, the following aspects come into play:
- DNS resources which is a server that allows receiving queries from clients using applications such as web browsers
- Root nameserver: this is the initial step to translate hostnames that are understandable to us into IP addresses
- TLD nameserver: its task is to perform the lookup for a specific IP address and save the last part of the hostname
- Authoritative nameserver: In the event that the authorized nameserver has access to the requested record, the IP address of the requested hostname will be returned to the DNS Recursor for later access by us
TechnoWikis will teach you what is the DNS that we use in our system and remember that this is generated by the Internet provider ISP or in case of failures we can resort to public domain DNS servers.
