IPCONFIG
Using
ipconfig /all or winipcfg Post your questions, comments, feedbacks and suggestions Using ipconfig /all or winipcfg When troubleshooting a TCP/IP networking problem, you can use the ipconfig command to get host computer configuration information, including the IP address, subnet mask, and default gateway. If it is running Win9x, ME, use winipcfg instead. An error occurred while renewing interface
I have a situation here where I could ping an IP of a 1. Incorrect WINS and DNS settings. Can ping IP but not hostname after installed/upgraded software Cause: the may modify the networking configuration in registry. Can receive IP packets but not send them Symptoms: When using ipconfig command, you may have no IP address or no Automatic Private IP Addressing (APIPA) address. You may be receiving IP packets but not sending them. Cause: These issues may occur if the Winsock registry keys are damaged or corrupted. Can't ping
my own IP address
Can't
obtain/renew IP addresses from the DHCP server
Resolutions: 1)
If this
is XP, obtain the latest service pack for Windows XP.
2) Use the Network Diagnostics tool to identify any failed settings. To do this, go to Help and Support>Use Tools to view your computer information and diagnose problems>Network Diagnostics>Scan your system. When the process finishes, check for any items marked "FAILED" in red, expand those categories, and view the additional details about what the testing showed. 3) Assign a static ip on the client and ping the DHCP server. If you can't ping the DHCP server, check the connection and hardware. 4) If you can ping the DHCP after assigning static ip, check the DHCP settings. 5) Make sure no firewall is running on your LAN. 6) Run Repair this connection if it is XP. Or use netsh to reset TCP/IP configuration. 7) If it is win98/w2k, remove and reinstall TCP/IP. 8) Try to upgrade the new NIC driver. 9) Make sure you don't run out of IPs in the DHCP scope. 10) If you use a router as DHCP, you may want to upgrade the firmware. Q: When I ping the server using one of the clients it says the host is
unreachable. Why?
Still need help, contact consultant Your feedback and contributions to this web site IP address conflicts
RESOLUTION:
|
Symptom: The Internet Assigned Numbers Authority (IANA) has reserved 169.254.0.0-169.254.255.255 for Automatic Private IP Addressing. If the computer can't get ip from DHCP, APIPA provides an address that is guaranteed not to conflict with routable addresses. |
Resolutions: 1) Make sure you have good
connection.
2) Check the hardware and settings.
3) Make sure the DHCP is working.
4) For the test, you can assign static ip. If static ip works, it is possible
DHCP issue. If static ip doesn't work, check the hardware or connection.
5) WinSock2 stack may be corrupted and need to repair.
Why the ipconfig shows 0.0.0.0 ip even you have assigned a static ip
Question: I have assigned a static ip, subnet to the computer, but the ipconfig shows IP address is 0.0.0.0 and subnet mask 0.0.0.0.. Why?
Answer: An existing IP address on the network has the same IP address. You may use tracert ip, WINS and DNS records to find out another computer using the same IP.
If your laptop users frequently disconnect from one network segment and reconnect to another network segment, they may not be able to access the second network. Resolution will be run ipconfig /registerdns.
