Promwad engineering cartoons: a DNS joke

 

The thing is, when there is a change in DNS, it needs to be propagated to all other servers. This process usually takes up to 24 hours.

In case you don’t know, DNS (short for Domain Name System), is basically an Internet service that translates domain names into IP addresses. It acts as an equivalent of a phone book for the Internet.

By the way, just a week ago Forbes reported that a DNS hijacking campaign has been targeting home routers of several producers. This was a threat to personal privacy leading to serious issues as capturing sensitive information and identity theft. How hackers managed to do this? They modified the DNS settings of the router and directed the traffic from clean well-known web services like Gmail, Netflix, PayPal, and Uber, to modified malicious ones. So, always be aware that you input your personal data to websites with the right address and domain name.
