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.
DNS Record Types Monitored
Track all common DNS record types for comprehensive monitoring
| Record | Purpose | Example |
|---|---|---|
| A | IPv4 address | 192.0.2.1 |
| AAAA | IPv6 address | 2001:db8::1 |
| MX | Mail server | 10 mail.example.com |
| CNAME | Alias to another domain | www.example.com |
| TXT | Text records (SPF, DKIM, etc.) | v=spf1 include:... |
| CAA | Certificate authority authorization | 0 issue "letsencrypt.org" |
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
