What is DNS Server?

Domain name system (DNS) is the system that is used to translate human-memorable domain names like todhost.com and hostnames like gh.todhost.com into the corresponding numeric Internet Protocol (IP) addresses as well as to identify and locate computer systems and resources on the Internet. So a DNS (Domain Name System) server is a type of web server used to interact with the domain name system, which is the global directory of domain names and corresponding IP addresses. DNS technology automatically translates long and confusing IP address (which are segmented number sequences separated by dots, such as 127.0.0.1) into standard domain names that are easier to remember.

When you use an alphanumeric address like "todhost.com" your computer needs to understand what numerical IP address it should contact to show up the content. Domain name server is a server responsible for keeping the file that contains information about the domain name(s) and corresponding IP addresses (zone file) as well as for providing the above-mentioned information during DNS queries.

Domain name servers are a fundamental part of the Domain Name System. Nameserver is a server on the Internet specialized in handling queries regarding the location of the domain name’s various services. In easy words, name servers define your domain’s current DNS provider.

All domains usually have at least two DNS servers which can be checked via Whois lookup tool.

For example: we provide name servers for all domains registered with us (they are called Todhost BasicDNS) and their values are:

ns1.todhost.com
ns2.todhost.com

When you make a request for anything related to the domain name, it gets sent to one of the name servers. In response, the DNS server sends back the IP address.  This works for the Web Site, Mail Servers, and anything else based on the domain name.

Free Email Forwarding and Dynamic DNS are some of the pros of using our default name servers.

What is the DNS Hierarchy?

The domain name system is operated in a hierarchy that keeps the domain name database separate, and the only servers that house the entire database are the aforementioned DNS root servers.
