About DNS Jumper

DNS Jumper is a Windows utility for changing DNS servers without editing network settings manually. Users select a server from a list and apply it, with an IPv6 option, and can restore ISP default settings, add custom servers, manage groups, back up settings, and test response times with an option to apply a result at startup. The site states it does not run in the background after the change is applied, describes its DNS list as a sample and warns against using unsecure servers, and notes that some security software can affect resolve times or ping measurement. It lists support for Windows XP through Windows 11 in x86 and x64.
