Another possible explanation is that there could be several hosts of one
sort or another whose addresses are 194.72.6.160 through 194.72.6.75 which
one wants to limit to receiving UDP traffic only. Time servers, perhaps,
receiving updates from an external source? SNMP logging database servers
receiving update from a monitoring station? Some ISP guy can probably come
up with better examples.
Given the information contained in the access list, it is not necessarily
true that the destination IP range is a whole subnet.

This is the subnet information.....Inverse Mask is 0.0.0.15 so the mask that
the
destination range resides on is 255.255.255.240 or /28.....
No. Subnet Hosts Hosts
Broadcast
Address From To
Address
10 194.72.6.160 194.72.6.161 194.72.6.174 194.72.6.175
Rose, if you look as the access-list this is a inverse mask working with the
subnet mask of the destination network.....What this is doing is filtering
out
on < udp port's > from the host listed below to the 10th Subnet of the Class
C destination address only.....Subnet=194.72.6.160
Hosts=194.72.6.161--194.72.6.174
Broadcast=194.72.6.175.....Hope this helps......
