The DNS translates memorable Domain Names/Hostnames into corresponding IP Addresses. Routers across a network route traffic utilising IP Addresses which are unsuitable for use by humans as a means to access websites, email addresses, etc. Instead more suitable representations in the form of HTTP URL (Uniform Resource Locator) or SMTP email addresses are used.
