Todo o mundo What’s DHCP? And why it’s recommended to use it? Imagine that you’re working as a SysAdmin for a large company with 500 desktop computers; you need to set to each desktop computer IP address, subnet mask, default gateway, DNS servers, and other network settings. How could you do that?
If you’ll try to perform this task manually you’re probably going to waste a lot of time on sitting on each computer 5-10 minutes, beside time, you can for example accidentally enter wrong IP address to few clients, or to type the same IP address to few clients too.
In order to solve these “problems” you can use Dynamic Host Configuration Protocol (or DHCP) in your network.
DHCP allows you to manage the networks’ IP addresses scopes and other TCP/IP settings like DNS, Default Gateway, etc. from central place, this central place called DHCP server. Beside the management, if there’s any problem you don’t need to run between your clients, you just need to connect to your server and to check the DHCP settings, as I mentioned – the DHCP works from central place, so if there’s a problem, it’s probably from the server, so you know where to go in case of problem and your saving time.
The DHCP server can provide easily IP addresses to clients automatically so you don’t even need to configure and set options in the client side, all you need is to setup DHCP server, configure scope options and some other TCP/IP settings in the server side and that’s it. You can provide to your clients IP addresses from the selected range that you’ve configured and some other TCP/IP options. |
