Nameserver is a specific server that has DNS software installed on it. Nameserver is an important part of the Domain Name System (DNS). It allows using domains instead of IP addresses.
When you register a domain name for your WordPress website, you need to specify one or more nameservers that are responsible for resolving your domain name to the correct IP address.
When a user enters your website’s domain name into their web browser, the browser sends a request to the nameserver specified for your domain. The nameserver then looks up the IP address associated with your domain name and returns it to the user’s browser. The browser then uses the IP address to connect to your website’s server and load your website.
In order for your WordPress site to be accessible on the internet, you need to make sure that your domain name is properly configured with the correct nameservers. This can typically be done through your domain registrar’s control panel, where you can specify the nameservers for your domain.
It is important to note that changes to your nameservers can take up to 48 hours to propagate across the internet, so it is important to plan ahead if you need to make changes to your nameservers. Additionally, if you are using a managed WordPress hosting provider, they may handle nameserver configuration for you, so you may not need to worry about it.
