Understanding the Basics of DNS

Before delving into DNS Server Error 1070, it’s important to understand the basics of DNS. The Domain Name System (DNS) is like a phonebook for the internet. It’s responsible for translating human-readable domain names like into machine-readable IP addresses like Without DNS, we’d have to remember numerical IP addresses to access websites, which would be impractical.

  1. DNS Hierarchy: DNS is structured as a hierarchy, with the root at the top, followed by top-level domains, second-level domains, and subdomains. This hierarchical structure makes it easier to manage the millions of domain names on the internet.
  2. DNS Resolution: When you type a domain name into your browser, your device sends a request to a DNS resolver to look up the IP address associated with the domain name. The resolver then queries authoritative DNS servers to find the IP address.
  3. DNS Caching: To speed up the DNS resolution process, resolvers cache IP addresses for a certain period. If you try to access the same domain name again, your device can retrieve the IP address from its cache rather than having to query a resolver again.
  4. DNS Records: DNS records are used to store information about domain names and their associated IP addresses. There are many types of DNS records, including A records, MX records, and CNAME records, each with a specific purpose.

Understanding the basics of DNS is crucial to troubleshoot and fix DNS Server Error 1070. In the next section, we’ll discuss the common causes of this error.
