How much does adding static IPs on AT&T cost?

I currently have AT&T Fiber internet service. It ranges anywhere from 300Mbps to 1,000 Mbps (Gigabit). If you are interested in renting static IPs along with internet service, AT&T customer service stated the following rental cost for a block of usable static IPs.

The block of addresses you receive will always have 3 deducted for the network base address, gateway, and broadcast address. For example, if you purchase a block of 8, you will only have 5 usable addresses. Below is a chart showing you the cost per IP based on the usable addresses you receive.

Usable Address Price Per Month Cost Per IP
5 $15 $3.00
13 $25 $1.923
29 $30 $1.034
61 $35 $0.574
125 $40 $0.320

More details here if you want  to learn about static IPs:

They bill you immediately and charge a percentage based on the number of days left in your current billing cycle. Customer service did not immediately tell me what my network settings would be, so I had to call them the next day to get the full network details.

Below is the guide I followed after customer service gave me the details. They offered to plug the details into the modem for me, but I chose to to perform the steps myself. Up to you depending on your comfort level.

The instructions below are perfect and worked exactly how I needed to.

Remember, once you enter in your network details, you have to navigate to IP Allocation to allocate an existing device to the WAN IP.

If you want to navigate to the screen manually:

  1. Navigate to
  2. Enter the access code that is on the modem
  3. Click on Home Network
  4. Click on IP Allocation

They don’t mention a policy of providing even greater number of IPs (128 IPs) but this is currently possible. It is not clear if you can rent a block greater tahn 128 IPs.
