pinged before offer ( dhcpd )
Q : What does this error log message mean ?
dhcpd Error Abandoning IP address 192.168.10.16: pinged before offer
A: Before the DHCP server assigns an IP address to a client, it pings the address to make sure nobody is using it already. In this case, the test failed, so the server “abandons” the address and picks another one to assign. Another computer may have already had that IP address statically assigned, or maybe it was dynamically assigned but the server and that client miscommunicated.
In either case, it is a harmless message and no action is necessary.
