As mentioned, it’s possible to change the nameservers for a domain. Nameservers direct your domain’s name to the company in control of its DNS settings. This is commonly the domain name registrar (the company you registered the domain name with). If your domain is hosted by anyone else, they provide alternative servers to point to instead.
This process, known as DNS propagation can take up to 72 hours to take effect, during which the ISP updates its caches with the new DNS information for your domain. It takes seemingly an age in internet time to update because your changes pass through several ISP nodes before reaching the hosting server.
If you want to change your nameservers, you need to find out who your domain service provider is. To find out the hostname of an IP Address, you may look up the domain name DNS records using WHOis DNS Lookup. Use this browser-based network tool for information regarding who is hosting a particular domain or to find out who your DNS provider is if you’re unsure.
Most domain registrars offer Whois Lookup options. ICANN regulates the Whois database, this database stores contact information for the owners of all domains registered. The database lists the name, address, email, and phone number of each domain owner alongside information regarding the domain availability status, your registration/expiration dates, and related info.
