DHCP Explorer

Performing specific network tasks will often require specialized utilities and subnet and LAN scanning to discover a particular type of servers is one of those jobs.
DHCP Explorer is a tiny but very useful application that can scan a network for Dynamic Host Configuration Protocol (DHCP) servers and return valuable information, including subnet mask or DNS servers.
Getting to know DHCP servers in very large networks is quite important for most of the users, and DHCP Explorer comes to lend them a hand with a clean interface and easy to use features.
It takes just a few seconds to install and run the application, so you shouldn't spend too much time trying to deal with these two steps.
The interface you'll see when running the app for the first time is quite user friendly and straightforward. You have to pick an adapter from the list, supposing you have more than one, and hit the 'Send DHCP Request' to get the information.
The program works very fast and all details should be provided in just a few seconds. DHCP Explorer thus shows you the IP address of the DHCP server, the subnet mask, the DNS server, the gateway address, the broadcast address and the IP lease time.
There's also an option to save the DHCP data separately in a text document and also to copy the information with the help of a single right click.
DHCP Explorer works without hampering computer performance at all, so it's safe to say that older machines will handle it just fine.
To sum up, DHCP Explorer is a handy utility if you want just that: get information on local Dynamic Host Configuration Protocol servers.
