OK, instead of netmasks it looks like he gave you Cisco wildcard patterns where the 0's are the bits that are constant and the 1's are the bits allowed to change. For this trivial case of a sequence of zeros followed by ones simply take the ones complement to get the desired netmask. > ... > [work-10_10] > ID-type= IPV4_ADDR_SUBNET > Network= 10.10.0.0 > Netmask= 0.0.255.255 Use 255.255.0.0 to identify the 10.10/16 network. -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote."
