WHOIS registrar change monitoring detects changes to your domain's SOA record and nameservers — the signals most likely to indicate a registrar transfer, domain hijacking, or unauthorised account changes.
⚙️How it works
Uptrue queries DNS SOA and NS records for your domain on each check cycle. If the hostmaster, primary nameserver, or NS records change from the baseline, an alert fires.
✓What Uptrue checks
- SOA hostmaster
- SOA primary nameserver
- Authoritative nameservers (NS)
- Combined change detection
⚠Alert conditions
- SOA or NS record snapshot changes from baseline
Why this matters
Domain hijacking often starts with an unauthorised registrar transfer. Catching it immediately via DNS changes gives you the best chance of reclaiming the domain before propagation completes globally.

?Frequently asked questions
Is this the same as a full WHOIS lookup?
We use DNS SOA and NS records as a proxy for registrar/registrant changes. Full WHOIS is rate-limited by most registries, making frequent polling impractical.
