How many Static IP addresses are available?

When you purchase a block of AT&T Static IP addresses, the installation technician will allocate three of the addresses to the following network functions - 1 address as the network base address; 1 address for your AT&T Gateway; and 1 address as your broadcast address. Therefore, the number of usable addresses is three less than the total number of addresses in your block. The current block sizes are:

Total Block Size	Usable Addresses
8	5
16	13
32	29
64	61
128	125
