Where are you?

Computers do not read website names the same way we look them up on the internet. While our language is literate, they work by binary numeric code. When we enter “www.usetelecom.com.br”, for example, it recognizes which website is searched through its IP (Internet Protocol). The IP is a numerical sequence that functions as a digital address and is used to identify computers on a network or web pages.

To find the IP corresponding to the name, the computer automatically queries a series of Domain Name System (DNS) servers.

For this, the servers are divided hierarchically into several types. Each type has different information. The most important of these is the root server, which has all the information on the world wide web.


The time that corresponds to the interval between the moment we look for the website and the loading of the page on our screen – the response of the consulted servers – is called latency. It takes milliseconds.

It does not seem like much, but we tend to be impatient with the least delay in responding to our demand.


One of the ways to ensure faster online browsing is to have your computer geographically close to the DNS servers – those that hold the mailing list of website names and their IPs.

You probably don’t know, but your ISP is probably already trying to connect to the nearest servers to perform this search.

To have an idea, Corporate Internet Premium users and everyone else on our network expect, on average, only a millisecond to receive the response from a searched website.

That’s because we have a copy of the “L-Root” root server in the Tascom Data Center, which is located at our headquarters in the Empresarial Mundo Plaza.
