tracert - a command used to determine the route taken by packets across an IP network.
usage : tracert ${IPADDR}
example : tracert yahoo.com
ipconfig - a command to display the network settings currently assigned and given by a network.
usage : ipconfig
example : ipconfig
Additional options : ipconfig/all, ipconfig/renew, ipconfig/release
arp - a command to show/remove the ARP informations
usage : arp -a
example : arp -d
sample result :
Interface: 192.168.0.188 --- 0x3
Internet Address Physical Address Type
192.168.0.254 00-02-44-73-ed-64 dynamic
Additional options : arp -d ( to remove and refresh the ARP table )
route - a command to display/add/remove routing table
To show the routing table
usage : route PRINT
example : route PRINT
To add a static route
usage : route ADD ${NETWORK} MASK ${NETMASK} ${GATEWAY} METRIC ${METRIC} IF ${INTERFACE}
example : route ADD 10.100.132.0 MASK 255.255.255.0 192.168.0.2 METRIC 3 IF 2
To remove a route
usage : route DELETE ${NETWORK} MASK ${NETMASK} ${GATEWAY} METRIC ${METRIC} IF ${INTERFACE}
example : route DELETE 10.100.132.0
To change a route
usage : route CHANGE ${NETWORK} MASK ${NETMASK} ${GATEWAY} METRIC ${METRIC} IF ${INTERFACE}
example : route CHANGE 10.100.132.0 MASK 255.255.255.0 192.168.0.2 METRIC 3 IF 2
pathping - a command with combinations of ping and tracert.
This command have more advantages comparing to tracert and ping as it provides statistics between each nodes from end-to-end but it has disadvantage whereby it would takes up more than 5 minutes to accumulate the results.
usage : pathping ${IPADDR}
example : pathping yahoo.com
The results showns will be as :

By using this command, you can have better analysis on the "lost" may have along the paths with how many packets are loss over 100 samples ping.
netsh dump - Dump all the network information as a script to the screen.
usage : netsh dump
With this command you can gather all the informations for your network devices. You may also dump all the informations into a text file for easier references.
usage : netsh dump > dump.txt
netsh interface ip - Configure the IP settings
To show IP config
Besides using the conventional "ipconfig/all", you may also use this command for all the IP settings informations .
usage : netsh interface ip show config
example : netsh interface ip show config
