Unable to ping my local computer IP from the same computer

[reneeshonnet]

My computer network is configured to have DHCP. When I issue “ipconfig” the IP address subnetmask and gateway are displayed, (IP address 192.168.1.10, Subnet mask 255.255.255.0, Default gateway 192.168.1.1) but I am not able to ping my machine by its own IP (from the same computer).

In my knowledge, for a machine to get the IP address the DHCP server should be reachable, or one can assign the IP address manually. (If DHCP server is not reachable APIPA may be taken by the client machine). In my case IP address is allocated to the Client machine, the ping to the self-address was fail.

In my knowledge in LAN knows that the reason of failure of self ping is due to the host based firewall rules or antivirus firewall functions. Otherwise there corrupted device driver or faulty NIC card.

That's correct. Do you have a question?

thank you very much for the valuable reply.

one technical persons says that this can be also due to

1. the wrong VLAN assignment.
2. switch trunk port-channel the allowed VLAN number was misconfigured.
3. ip helper-address misconfiguration in DHCP realy agent.

and I strongly disagree with what he says.
