[Whilst the topology shows only two hosts on each LAN, you should configure four hosts on each LAN.] Network Information
The WAN IP network address between Dundee and Glasgow is with a subnet mask of The WAN IP network address between Edinburgh and Glasgow is with a subnet mask of This is clearly shown on the network topology.

Dundee information
The LAN for Dundee has been assigned an IP network address of Each subnet of the above network needs to accommodate 14 host addresses. The subnet mask will be This is worked out by borrowing 4 bits from the final octet and is shown in the table below.

Table 1 Custom Subnet Mask for Dundee

Use the 6th usable subnet for the LAN. Do not use subnet zero as the first usable subnet. The table below shows how the 6th usable network can be identified. |Network |Network ID...
