The Domain Name System DNS is among the most foundational and most overlooked components of Nigerian business digital infrastructure. It is the system that translates the human-readable domain name of your website into the numerical IP address that computers use to locate your server. When a visitor types your website address into their browser, a DNS query resolves your domain to the correct server address before the first byte of your website is delivered. When you send an email from your business domain, DNS records verify that your email server is authorised to send on behalf of that domain. Every element of your business’s online presence website, email, subdomains, cloud services depends on DNS configuration being correct. And yet most Nigerian businesses have never consciously managed their DNS.
DNS misconfiguration is a deceptively common and disproportionately consequential source of business digital problems in Nigeria. An incorrectly configured MX record the DNS record that directs email to the correct mail server results in business email being undeliverable, often without the sender receiving a clear error message. An incorrectly configured A record the record that points a domain to the correct web server results in the website being inaccessible. And an absent or incorrectly configured SPF or DKIM record the records that authenticate the business’s email as legitimate results in business emails being classified as spam by recipients’ email providers, invisibly destroying email communication that the sender believes is being delivered.
Email deliverability the reliable arrival of business emails in recipients’ inboxes rather than spam folders is heavily dependent on three DNS records that most Nigerian businesses have never configured correctly. SPF Sender Policy Framework specifies which servers are authorised to send email on behalf of your domain, helping recipient systems distinguish legitimate messages from spoofed ones. DKIM DomainKeys Identified Mail adds a cryptographic signature to outgoing emails that allows recipient systems to verify that the message was sent by an authorised server and was not modified in transit. And DMARC Domain-based Message Authentication, Reporting, and Conformance builds on SPF and DKIM to specify how recipient systems should handle messages that fail authentication. Without all three correctly configured, Nigerian business emails are vulnerable to spam classification and their domain is vulnerable to being spoofed in phishing attacks.
DNS infrastructure is also an attack surface that requires deliberate security management. DNS hijacking where an attacker modifies DNS records to redirect website traffic or email to malicious servers is a known attack type that has affected Nigerian businesses and their customers. DNSSEC DNS Security Extensions provides a layer of cryptographic verification that protects against DNS record tampering. And the security of the registrar account that controls DNS records the account where domain registration and DNS management occur requires the same strong credential and MFA practices as any other critical business account.
E15 Technologies Limited’s Infrastructure and Support service includes DNS audit and management for clients whose DNS configuration requires verification, correction, or ongoing maintenance. Our DNS audit reviews all records associated with your domain verifying that website, email, and any cloud service DNS configuration is correct, complete, and optimally configured for deliverability and security. Where misconfiguration exists, we correct it with a systematic understanding of the dependencies between records.
