What Is DNS?

DNS is the addressing system of the internet. Learn how it works and how SwishDNS keeps your domains fast, reliable, and always reachable.

Understanding the Domain Name System (DNS)

DNS (Domain Name System) is like the internet’s phonebook. When you type a domain name like example.com into your browser, DNS converts that name into an IP address so your device knows which server to connect to.

How DNS Works (Simplified)

When someone enters a domain name, their device performs a DNS lookup:

SwishDNS provides the authoritative DNS hosting for your domains — the source of truth that tells the internet where your services live.

Why Reliable DNS Matters

If DNS is slow, misconfigured, or offline, your website or application can appear down even if your servers are healthy. A single wrong record can break email delivery, stop users reaching your site, or send traffic to the wrong place.

Common DNS Record Types

A Record

Maps a domain or subdomain to an IPv4 address (e.g., 203.0.113.10).

AAAA Record

Maps a domain or subdomain to an IPv6 address.

CNAME Record

Creates an alias from one name to another. For example: www.example.comexample.com.

MX Record

Specifies which mail servers are responsible for receiving email for your domain.

TXT Record

Stores text data. Commonly used for verification, SPF, DKIM, DMARC, and other service-specific values.

NS Record

Points to the authoritative nameservers for your domain — for example ns1.swishdns.net and ns2.swishdns.net.
