Mac bind

can anyone tell me how to bind IP to a particular MAC address ?

thanks

Static ARP configuration example,
http://wiki.mikrotik.com/wiki/How_to_secure_a_network_using_ARP

is it also applicable if i am running Mikrotik OS in Bridge mode ? Cause when i am doing as per the instruction here, i only get that anything other than the existing mac entry can’t ping my router. But ping to yahoo or others is still existing. can you please tell me what should i do ?
