Understanding DNS

If you run a website, you need to know how important it is to keep everything up to date and functioning properly. One crucial aspect of website maintenance is updating DNS records. DNS or Domain Name System is the system that translates a website’s domain name into an IP address that computers can understand. Without up-to-date DNS records, your website won’t be able to function properly.

In this step-by-step guide, we’ll walk you through the process and answer some frequently asked questions to make sure you have everything you need to keep your website running smoothly.

Some Common DNS Records

  • A record (Address record): This type of DNS record maps a domain name to an IP address. It’s the most commonly used type of DNS record and is used to direct traffic to a specific web server.
  • CNAME (Canonical Name) record: A CNAME record maps one domain name to another. For example, if you have multiple subdomains that point to the same IP address, you can create a CNAME record to avoid redundancy.
  • MX (Mail Exchange) record: An MX record specifies the mail server responsible for accepting email messages on behalf of a domain name. This type of DNS record is essential for email delivery and must be set up correctly to ensure reliable email service.
  • TXT (Text) record: A TXT record allows you to add arbitrary text to a DNS record. This can be used for a variety of purposes, such as adding SPF (Sender Policy Framework) or DKIM (DomainKeys Identified Mail) information to your DNS records.
  • SRV (Service) record: An SRV record is used to specify the location of a specific service, such as a SIP (Session Initiation Protocol) server for VoIP (Voice over Internet Protocol) calls.
  • AAAA (IPv6 Address) record: This type of DNS record maps a domain name to an IPv6 address. It’s used to support the newer IPv6 protocol, which provides more IP addresses than the older IPv4 protocol.
