Domain nameservers are part of the Domain Name System (DNS). They handle requests for where a domain’s services are located, such as its website files, email hosting, and other connected services.
When someone visits a domain, a DNS lookup checks the domain’s nameservers. These nameservers then point to the correct DNS records, which tell the internet where to load the website or deliver email.
In simple terms, nameservers act like the “address book” for your domain, translating the domain name into the correct IP address.
