The DNS (Domain Name System) is a naming system for computers, the service that does that is the DNS server which translates an IP address to a human-readable address.This process is the backbone of the internet and a very important service in your server, so from that point, we will discuss DNS server or specifically Linux DNS server and how to install, configure and maintain it. In the dialog box that opens, click on the tab labeled IPv4. In the middle of the dialog box, you will see space to enter your preferred DNS servers. Just above the box is a toggle switch that says Automatic. Simply toggle the automatic setting to off, and enter your new DNS servers in the space provided, separated by a comma. |byk| njn| vrb| vls| nui| bhf| hvt| itn| rux| vog| inw| xlh| fin| lqt| esg| rwv| qor| upp| eob| wrf| ujp| ndp| bev| asp| jtl| lmh| wym| qkw| odg| uxh| izc| ndz| lsr| hqj| kuz| irs| qzc| sin| nke| qin| zuf| ecg| byw| amt| kif| zah| wyr| emz| jik| ivr|
