DNSinfrastruktuuria

DNSinfrastruktuuria refers to the interconnected system of servers and protocols that enable the Domain Name System (DNS) to function. This infrastructure is essential for translating human-readable domain names, such as www.example.com, into machine-readable IP addresses, like 192.0.2.1, which are used by computers to locate each other on the internet. The DNS infrastructure is hierarchical, with root name servers at the top, followed by top-level domain (TLD) servers (e.g., .com, .org), and then authoritative name servers responsible for specific domains. When a user types a domain name into their browser, their computer queries a local DNS resolver, which then traverses this hierarchy to find the correct IP address. This process ensures that users can access websites and online services without needing to remember complex IP addresses. The robustness and security of the DNS infrastructure are critical for the stable operation of the global internet. Various organizations and entities manage different parts of this infrastructure to ensure its reliability and accessibility.
