What are nameservers?

The authoritative servers (NS records) that answer DNS queries for a domain — in practice, which DNS provider controls the domain’s records.

Why do my nameservers still look wrong after a change?

Nameserver delegation updates on the parent zone’s TTL, so allow time and recheck. If they remain wrong, confirm the change actually saved at your registrar or DNS host.
