HoverIP is a powerful set of IP utilities, all inside a single box ! With HoverIP you can display your IP configuration (on all network cards), perform different tasks like NSLOOKUP, PING, TRACEROUTE, SCAN PORTS or network, and manage your ROUTES in a very convenient way !
IPconfig: Displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings.
NSLOOKUP: look up and find IP addresses in the DNS
Routing table: contains information about the topology of the network immediately around it. The construction of routing tables is the primary goal of routing protocols. Static routes are entries made in a routing table by non-automatic means and which are fixed rather than being the result of some network topology 'discovery' procedure.
Traceroute: a tool used to show the route taken by packets across an Internet Protocol (IP) network
fine, very useful :-)
