| Nameserver lookup or DNS Lookup is just a tool for obtaining information about any domain name registered with a specific host. Generally, DNS is a query/response system, designed to provide a point of contact for hosts and visitors alike. It is implemented through a domain name server, which is a computer which runs queries on behalf of customers, returns the results based on a specific pattern, usually a dot-com or dot-net. The customer then gets the address (IP address) assigned to that domain name, which is typically represented by its IP address in an Internet Protocol (IP) address. Nameserver lookup works in reverse too. As previously explained, DNS is an acronym for Domain Name System. It is also known as root server, or DNS root. A DNS resolver, is the application responsible for translating domain names into IP addresses and vice versa. In simple terms, a resolver acts as a "bridge" between a domain name and an IP address. Resolvers are commonly used as part of reverse or recursive DNS applications, or sometimes independently as well. There are two types of DNS servers - the first is the authoritative, or root, server. This server is given the domain name from which all other DNS servers will access. The second type is called the authoritative server but is not a root server. Instead, it is responsible for maintaining information about the Top Level Domain (TLD) and DNS zone files and serves as a connection gateway between the DNS system and other servers. Nameserver lookups are basically DNS lookups that depend on the information contained in the nameservers. In simple terms, nameservers translate domain names into IP addresses. They do this by delegating reads and writes to DNS zones or names. However, there are some cases where nameservers can't translate domain names and rely on DNS zone files alone. For example, a business may have multiple mail servers but want to maintain separate email addresses for each staff member. This means that every person has his or her own email address and can make local copies of important documents. To solve this problem, nameservers are added to the domain name system so that each staff member can add his or her own dns records to the system. Each new record corresponds to the corresponding IP address. Thus, when a person sends an email to his colleague, the colleague's email address is notified and the person's record is updated accordingly. Another popular use for nameservers is when a domain name system is combined with a domain registrar. Some registrars offer domain registration services while others allow customers to buy up domains directly from the domain registrar. Customers can then use their nameservers to log in to their domain names at the domain registrar. This is a convenient way to manage multiple dns records and because the records are maintained in the companies own servers, users can be assured of privacy. However, the main reason why people use nameservers for the purpose of nameserver lookup is to access publicly available domain name databases. There are many places on the internet where you can search for domain name extensions, such as whois and domain registers. Most of these places are free, but there are some which charge minimal fees. In this case, users make use of their nameservers to access these databases, since the only cost is the few dollars per search. For instance, most cloudflare customers make use of dns lookup by domain name to look up common misspellings. There are also times when clients make use of cloudflare's private cloud, which offers better security. Some of cloudflare's private cloud services are name explorer, which allows users to enter domain names into the search bar, to browse through all available names, or to restrict searches to a particular level. These level dns nameserver services are usually more expensive than other cloud services. Therefore, it is not uncommon for business owners to pay an annual fee to cloudflare for maintenance and support of its private cloud. |
