Important Notes :
If using a BT phone line you must use an ADSL modem router, if using a NTL or
cable phone service you must use an appropriate cable router.
Be aware that when connected to the Internet, the router has two IP addresses:
internal and external. The internal address is seen by devices connecting to it’s
Ethernet ports, the external address represents it’s connection to the local
exchange via the telephone line.
Tasks :
•
Find out what the external IP address is, this is assigned by the customer’
s Internet
Service Provider
•
Find out : is this a fixed IP address, ie: “Static, or does it change, ie: “Dynamic” ?
•
