The AdapterCount property returns the number of local and
remote dial-up networking adapters available on the local system.
This value can be used in conjunction with the AdapterAddress
property array to enumerate the IP addresses assigned to the various
network adapters.
Note that it is possible that the AdapterCount property
will return 0, and AdapterAddress(0) will return an empty
string. This indicates that the system does not have a physical
network adapter with an assigned IP address, and there are no dial-up
networking connections currently active. If a dial-up networking
connection is established at some later point, the
AdapterCount property will change to 1, and the
AdapterAddress(0) property will returned IP address allocated
for that connection.
