DNS Tips, Tricks,, and Tangles


That stands for Domain Name System. Internet users do not have to be able to define the term in order to use it. It is enough to know that this is how Internet surfers are able to reach websites using popular names. In fact, everything reachable on the Internet must have a numeric address, i.e., IP address, and Internet spaces are reachable only at their IP address location. However, who would ever remember or ever use 216.58.217.206 in order to reach Google? No one could, nor does anyone need to. The domainn name system provides the valuable service of translating Google.com into 216.58.217.206 so that the Google website is reachable with that catchy website name Google.com.
