a dhcp server needs to see a packet on the network from a host requesting a dhcp configuration message. therefore we need to mimic a dhcp request,, and this tool will do that and print the response, which will be an ip address, netwmask, default router, and optionally dns resolvers, ntp servers etc. – Paul M Jun 22 at 14:28
The IPv4 address is your PC’s IP address on the local network. The address is assigned by the router, using something called DHCP. The subnet mask is a type of filter that helps PCs on the network better see each other. The default gateway is the IP address of the router. Make a note of it. DHCP. Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (i.e., a scope) configured for a given network. DHCP assigns an IP address when a system is started, for example: A user turns on a computer with a DHCP client.
