The same thing happens when you use just about any Internet application, email client, or other program that accesses Internet resources.
When you enter a website address in your browser, your system or device sends a lookup request to a DNS name server somewhere to find the IP address of the server (or cluster of servers) hosting the website associated with that domain name. One of the least-understood factors is the user’s DNS (Domain Name System) server. Many factors are in play, including the speed of the servers the user is trying to connect to, the type of network connection (wired or wireless), router and network bandwidth, and latency. Most people assume that their Internet connection’s peak bandwidth determines their broadband connection’s overall performance.
