Nameservers (also called DNS servers) are a fundamental part of the internet infrastructure. Here's what they do:
What are nameservers?
Nameservers are specialized servers that translate human-readable domain names (like (link unavailable)) into machine-readable IP addresses (like 192.0.2.1).
How do nameservers work?
1. When you enter a domain name in your browser, your computer sends a request to a nameserver.
2. The nameserver checks its database or caches to find the associated IP address.
3. If found, the nameserver returns the IP address to your computer.
4. Your computer then connects to the IP address, loading the website or online resource.
Types of nameservers:
1. Authoritative nameservers: Store the original DNS records for a domain.
2. Recursive nameservers: Query other nameservers to find the IP address.
3. Caching nameservers: Store recently resolved domain names and IP addresses.
Nameserver roles:
1. Primary nameserver: The main nameserver for a domain.
2. Secondary nameserver: A backup nameserver in case the primary fails.
In summary, nameservers play a crucial role in connecting users to online resources by translating domain names into IP addresses. If you have specific questions about nameservers or DNS, feel free to ask!
