Domain and Nameserver Lookup
Enter a domain to see its authoritative nameservers, their IPs, RDAP details, SOA data and approximate IP geolocation.
How it works
We query NS and SOA through DNS, registration details through RDAP, and approximate IP geolocation through ipwho.is.
Limitation: RDAP dates can reflect broader registration changes, while an SOA serial reflects a DNS-zone update. Neither confirms the exact date when nameservers changed.
Frequently asked questions
Can I know the exact date of an NS change?
Domains don’t have a public NS change log. We use RDAP “last changed” (usually matches registrar updates) and, if the zone’s SOA serial is in YYYYMMDDnn format, that date as an additional hint.
What counts as a “server IP”?
We show authoritative DNS-server IPs (NS A/AAAA). For convenience we also list the content-server IP (domain A/AAAA).
