DNS-02 / DNS RECORDS
NS Lookup
Find the authoritative nameservers responsible for a domain.
About the NS Lookup
NS (Nameserver) records identify the authoritative DNS servers for your domain — the servers that hold the real answers for all your other records. Checking them confirms your domain is delegated to the right DNS provider. This tool lists the authoritative nameservers for any domain.
What this tool checks
It resolves the NS records for your domain, showing which nameservers the domain is delegated to at the registry level.
Why this matters
If your nameservers don't match your DNS provider, none of your other DNS changes will take effect. This is the first thing to verify when DNS changes aren't propagating.
Frequently asked questions
What are nameservers?
Nameservers are the authoritative DNS servers that store and answer queries for your domain's records. Your registrar delegates your domain to them, and they serve your A, MX, TXT, and other records.
How many nameservers should a domain have?
At least two, for redundancy. Most providers give you two to four. Having more than one ensures DNS keeps working if one server becomes unavailable.
Why don't my DNS changes take effect?
Usually because your domain's nameservers at the registrar don't point to the DNS provider where you're editing records. Confirm the NS records here match your provider before troubleshooting individual records.
