DNS (Domain Name System) records control critical aspects of your domain's functionality—from where your website points to how your email is delivered. Unexpected DNS changes can cause website downtime, email delivery failures, or even indicate security issues like DNS hijacking. Domainyze's DNS Monitoring helps you detect and respond to unauthorized or unexpected DNS changes immediately.
How It Works
DNS monitoring is available for domains within your Portfolio monitoring type.
- Initial DNS Snapshot: When you add a domain to your Portfolio, Domainyze performs a comprehensive DNS lookup to capture all current DNS records (A, AAAA, MX, NS, TXT, CNAME, CAA, SOA, SRV, SPF, DKIM, and DMARC).
- Regular Checks: Our system periodically queries your domain's DNS records to detect any changes.
- Change Detection: We compare each new check against the previous snapshot to identify what records were added, removed, or modified.
- Immediate Alerts: When DNS changes are detected, Domainyze sends you instant notifications via email and webhook (if configured), detailing exactly what changed.
Why Is DNS Monitoring Important?
- Detect Security Threats: Identify potential DNS hijacking attempts or unauthorized nameserver changes that could redirect your traffic.
- Prevent Email Delivery Issues: Get alerted when MX records change unexpectedly, which could disrupt your email service.
- Avoid Website Downtime: Know immediately if A/AAAA records are modified, potentially causing your website to become unreachable.
- Track SPF/DKIM/DMARC Changes: Monitor email authentication records to maintain email deliverability and prevent spoofing.
- Audit Trail: Maintain a complete history of all DNS changes for compliance and troubleshooting purposes.
Supported DNS Record Types
Domainyze monitors the following DNS record types:
- A & AAAA: IPv4 and IPv6 addresses (where your domain points)
- MX: Mail exchange servers (email routing)
- NS: Nameservers (DNS authority)
- TXT: Text records (general purpose)
- CNAME: Canonical name (domain aliases)
- CAA: Certificate Authority Authorization (SSL control)
- SOA: Start of Authority (zone information)
- SRV: Service records (service location)
- SPF: Sender Policy Framework (email authentication)
- DKIM: DomainKeys Identified Mail (email authentication)
- DMARC: Domain-based Message Authentication (email policy)
By integrating DNS monitoring into your Domainyze Portfolio, you add a critical layer of security and reliability monitoring for your domains.
