How to avoid IP conflicts from occurring.Types of IP conflicts and how to fix them.It is important that you detect and resolve IP address conflict to ensure smooth network operations. where nge0 is whatever your ethernet device is.Windows abstractly describes the cause of this error in the network error message as, "Another computer on this network has the same IP addresses as this computer." This means your device is experiencing an IP conflict with another device or host in your network.
Google suggests you can release/renew your lease on the Solaris 10 system by doing this: # ifconfig nge0 dhcp release If you set your dhcp server's syslog to pick up *.debug, dhcpd will drop all kinds of detail into your messages file and you can see exactly what it thinks is happening. (Sometimes when the server says "no", the client just hangs on to the lease until it expires before starting the dhcp process over again.) Sometimes it will ask the server, "can I renew this existing lease?" and the server will say "yes, you can keep using it." Most of the time though the server will say "no", forcing the client to begin the dhcp process from scratch, resulting in the reservation being issued. The only exception to this rule is if the client already has a lease. So either your reservation is wrong (typo, or server not restarted to pick up the reservation), or your client isn't using your server.
DHCP client requests for IP lease (MAC & ID are included in the request) and your server saves it as combination of MAC address and OS ID in the database (some file usually for dnsmasq and dhcpd). Let's say you have some host with Windows or Linux. How can I take the advantage of it, why a wildcard could be good or bad.
