Nameserver change monitoring resolves your domain's NS records on each check cycle and alerts when the authoritative nameservers differ from the stored baseline. Nameserver changes cause global DNS propagation and can cause service outages.

⚙️How it works

Uptrue resolves NS records for your domain and sorts them for consistent comparison. If the set of authoritative nameservers changes from the baseline, an alert fires with the old and new nameservers.

⚠Alert conditions

Nameserver records differ from stored baseline

Why this matters

Nameserver changes happen during domain transfers, registrar migrations, and DNS provider switches. Unauthorised nameserver changes may indicate account compromise. Authorised changes still need monitoring to verify correct propagation.

?Frequently asked questions

What's the difference between this and DNS record monitoring?

DNS record monitoring watches A, MX, NS, TXT records together. Nameserver monitoring focuses specifically on NS changes which affect all records globally.

How long does DNS propagation take?

Typically 24-48 hours, though often much faster. TTLs determine how quickly cached records expire.
