Workstation TCP/IP Utilities

Workstation TCP/IP Utilities

In addition to using ping, tracert, and Telnet on a Windows workstation to test Network- and Application-layer connectivity, you can use the following utilities to verify the configuration of the workstation.

Utility	Description
Ipconfig	Ipconfig displays IP configuration information for network adapters including: IP address and mask Default gateway DNS and WINS server addresses IP address of the DHCP server used for configuration MAC address Use the ipconfig command as follows: Use ipconfig to view IP address, subnet mask, and default gateway configuration Use ipconfig /all to view detailed configuration information. Use ipconfig /release to release the IP configuration information obtained from the DHCP server. Use ipconfig /renew to request new IP configuration information from the DHCP server.
Arp	The ARP cache keeps a mapping of IP address to MAC addresses. If the IP address or MAC address changes, the value in the cache might be out of date. Use the arp -a to list a host's ARP cache. Use arp -d to clear the ARP cache. Use arp -d * to remove all dynamic ARP entries from the ARP list. Note: Switches used with arp are case-sensitive. Arp -a is not the same thing as arp -A.
Nslookup	Nslookup resolves (looks up) the IP address of a host name. Displays other name resolution-related information such as the DNS server used for the lookup request.
