particular row and the subnet mask for the subnet in the Subnet Mask ﬁeld in that row.

For example:

	IP Subnets
	IP Address	Subnet Mask
	----------------	---------------
#1:	192.128.117.162	255.255.255.0
#2:	192.128.152.162	255.255.0.0
#3:	0.0.0.0	0.0.0.0
#4:
#5:
#6:
#7:
#8:

■To delete a conﬁgured subnet, set both the IP address and subnet mask values to 0.0.0.0, either explicitly or by clearing each ﬁeld and pressing Return or Enter to commit the change. When a conﬁgured subnet is deleted, the values in subsequent rows adjust up to ﬁll the vacant ﬁelds.

Note that the subnets conﬁgured on this screen are tied to the address serving pools conﬁgured on the IP Address Pools screen, and that changes on this screen may affect the IP Address Pools screen. In particular, deleting a subnet conﬁgured on this screen will delete the corresponding address serving pool, if any, on the IP Address Pools screen.
