A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?
A. hosts file
The predecessor to DNS, a static text file that resides on a computer and is used to resolve DNS hostnames to IP addresses. Automatically mapped to a host’s DNS resolver cache in modern systems. The hosts file has no extension.
Hosts file is checked before DNS. It's actually a fun and simple way to hack a system. I had to use it once to keep users from using a PC running an XRAY controller to get on Facebook and other social media sites. Quick 'n' dirty ;-)
The hosts file is a local system file that maps hostnames to IP addresses and can override normal DNS resolution
. When only one user is experiencing resolution issues while others can access the website normally, this strongly suggests a local configuration problem rather than a network-wide DNS issue.
