Domain Monitoring

Don't let a domain expiry kill your business

A lapsed domain can take your entire business offline — or worse, get snatched by someone else. Vantaj tracks domain registration expiry, DNS records, and WHOIS changes so you're never caught off guard.

5 stages

90 / 60 / 30 / 7 / 1 day alerts

Expiry date tracking

Monitors WHOIS registration data to know exactly when your domain expires. Get alerted at 90, 60, 30, 7, and 1 day before — even if auto-renewal is on.

DNS record monitoring

Tracks A, AAAA, CNAME, MX, TXT, and NS records. Any unexpected change triggers an alert so you catch misconfigurations and unauthorized changes fast.

WHOIS change detection

Detects changes to registrant info, nameservers, and registrar. If someone transfers your domain without authorization, you'll know immediately.

Multi-stage alerts

Configurable alert thresholds give your team time to act. Escalating notifications ensure the renewal doesn't fall through the cracks.

DNS change history

Every DNS record change is logged with before/after values and timestamps. A full audit trail for debugging and compliance.

Protect your brand

An expired domain can be registered by anyone — including competitors and squatters. Continuous monitoring is the simplest insurance policy.

What we monitor for each domain

Check	Details
Registration expiry	WHOIS-based expiry date tracking with 5-stage alerts at 90, 60, 30, 7, and 1 day
Nameserver records (NS)	Detects nameserver changes that could indicate unauthorized transfers
A / AAAA records	Tracks IP address changes for your domain's DNS resolution
MX records	Monitors mail server configuration to prevent email delivery failures
TXT records	Watches SPF, DKIM, DMARC, and other TXT records for changes
CNAME records	Alerts when aliases change, which could break CDN or service routing

How it works

01 — Add your domains

Paste a domain, we handle the rest

Enter any domain name and Vantaj automatically looks up WHOIS data, DNS records, and registration details. No verification steps, no DNS changes required.

02 — Continuous scanning

WHOIS and DNS checked regularly

Domain registration and DNS records are polled continuously. Changes and approaching deadlines trigger alerts automatically — no manual checking needed.

03 — Early warning alerts

Up to 90 days of warning

Receive alerts at 90, 60, 30, 7, and 1 day before your domain expires. For DNS or WHOIS changes, you're notified within minutes of detection.

04 — Full audit trail

Every change is logged

DNS record changes are recorded with before/after snapshots. Trace exactly what changed, when, and spot misconfigurations before they cause outages.

Frequently asked questions

How does domain expiry monitoring work?

Vantaj queries WHOIS/RDAP data for your domain on a regular schedule. It extracts the registration expiry date and sends you countdown alerts at 90, 60, 30, 7, and 1 day before expiry.

Will I get alerted even if auto-renewal is enabled?

Yes. Auto-renewal can fail silently due to expired payment methods, registrar policy changes, or domain disputes. Vantaj alerts you regardless, so you can verify the renewal happened.

What DNS record types are monitored?

A, AAAA, CNAME, MX, NS, and TXT records are all tracked. Any change to these records triggers an alert with before/after values.

Can I monitor domains I don't own?

Yes. Domain monitoring works by querying public WHOIS and DNS data, so you can monitor any domain — including competitor domains or domains belonging to critical vendors.

Does domain monitoring count against my monitor quota?

Domains are tracked separately from uptime monitors. Adding a domain gives you expiry, DNS, and WHOIS monitoring without consuming an uptime monitor slot.
