ISP Checklist

If you are contracting with an Internet service provider (ISP) for Internet access, you must choose
between a single-user account and a multiuser LAN account. You can connect your multiuser
network through a single-user account by using the Network Address Translation (NAT) feature of
your router.

Single-User Account

With a single-user account, your ISP assigns only one registered Internet Protocol (IP) address.
This address may be a permanent fixed address or it may be a different address assigned
dynamically each time you log in to the account. The NAT feature of your router maps the
IP addresses of your network to this address for accessing the Internet. Some applications may
be incompatible with NAT.
