Detect invalid entries in the ARP cache
The invalid entry exists in the ARP cache may be due to the two computers on the network caused by the same IP address. These conflicts are likely to be an incorrect static IP address because the address assigned by DHCP is not It will cause an address conflict.
Verify incorrect static IP address
One with the allocation of the static address maintains a static address (and the corresponding MAC address) table.
2 By looking for the manufacturer bytes of the MAC address of the corresponding network adapter, inference, the adapter has a given Mac. Other OUIS can compare the MAC address in the ARP cache to determine if the input static address is wrong. .
