What is Nameserver Lookup?
A nameserver (NS) lookup is a DNS query that retrieves the authoritative name servers responsible for a domain. These servers store the domain's DNS records and handle queries for subdomains or other record types.
NS records are crucial for DNS resolution, directing queries to the correct servers. They typically include the hostname of the nameserver and its TTL (Time to Live).
Common Uses of Nameserver Lookup
- Verifying domain configuration and delegation.
- Troubleshooting DNS issues or propagation delays.
- Identifying hosting providers or DNS services used by a domain.
- Ensuring proper setup during domain transfers or migrations.
Note: NS lookup results depend on the domain's DNS configuration. Changes to NS records may take time to propagate across the internet due to caching.
