DNS Monitoring

FlareWarden tracks DNS records for all your uptime monitors. Detect unauthorized changes to your DNS configuration and troubleshoot resolution issues.

Automatic DNS Monitoring

DNS monitoring is automatic for all uptime monitors

FlareWarden resolves your domain's DNS records with each check and tracks changes over time.

What We Detect

Comprehensive DNS change detection and alerting

Resolution Failures

When DNS stops resolving entirely (NXDOMAIN, timeout, etc.)

IP Address Changes

When A or AAAA records point to different IP addresses

MX Record Changes

Changes to mail server configuration that could affect email delivery

TXT Record Changes

SPF, DKIM, or verification record modifications

WHOIS Tracking

Monitor domain registration and ownership information

FlareWarden tracks WHOIS records for your domains to help you stay informed about registration status and ownership changes.

Expiration Tracking

Know when your domain registrations expire so you can renew them before losing ownership.

Registrar Changes

Detect when a domain is transferred to a different registrar, which could indicate unauthorized transfers.

Nameserver Changes

Track when nameserver records change in WHOIS, which affects where your DNS is hosted.

Status Changes

Monitor domain status flags like clientTransferProhibited, serverHold, and other registrar locks.

Why DNS Monitoring Matters

Critical security and operational insights from DNS tracking

Detect DNS Hijacking

Unauthorized DNS changes can redirect your visitors to malicious sites. Early detection limits exposure.

Troubleshoot Outages

DNS issues can look like server outages. Knowing DNS is the problem saves debugging time.

Track Infrastructure Changes

Keep a record of when IPs changed during migrations or CDN switches.

Webhook Events

Integrate DNS alerts with your existing tools

DNS events can trigger webhooks:

dns.failed - DNS resolution failed

dns.recovered - DNS resolution recovered
