Introduction to 'DNS'
Your guide to pathway services
DNS is an abbreviation for Domain Name System.
Internet services can only be addressed by numeric addresses (IP addresses). There are millions of internet services (websites, etc.) that use these numeric addresses and these numeric addresses are mapped to names to make it easy for human beings to access these services.
DNS servers take care of these numeric addresses and point domain names to correct numeric addresses. For example, the domain qwert.us translates to 66.212.164.12. It’s much easier to remember URLs and email addresses than having to remember a number. With the DNS system, website users only need to remember www.qwert.us and not qwert's numeric IP address.
DNS plays an equally important role in ensuring that emails get delivered correctly. This is done using MX records.
Domain names need to be registered with Name Registrars or with Pathway. This ensures that everyone gets a unique domain name on the World Wide Web. Registrars are authorities that maintain and keep DNS records.
