Static or Dynamic IP Addresses
Static IP addresses are always recommended over dynamic IP addresses as they ensure
communication uptime (as long as the equipment is functioning). For mission critical
applications, such as alert notification, this communication uptime is required. For other
applications, using a dynamic IP address is more affordable. When using Dynamic IP
Addresses the IP address may not be available at all times.
For Cingular:
To use the Cingular/AT&T network, the cellular account will need to be setup with a
Custom APN. A Custom APN for static IP addresses incurs a one time setup fee of $500
and then a single fee of $3/month per account. Information on Cingular packages can be
found here:

To setup a Cingular dynamic IP address, the account will need to be setup with a Custom
APN, but does not incur the monthly fee.
