Static IP Addresses

A Static IP Address is an IP Address that is associated with your account that never changes and can be assigned to a specific device. Every time that you connect to the AT&T Network the Static IP address will route traffic to the computer or other device that can be assigned an IP address (such as a Router or Firewall). This allows you to host a variety of applications on your computer that can be accessed remotely.

AT&T Static IP is useful for consumers and many small businesses that have needs such as:

• Host a web, mail or FTP server
  
• Access a corporate network remotely
  
• Host a webcam for video streaming
  
• Use some video conference applications
  

When you purchase a block of AT&T Static IP addresses, three of the addresses will be allocated to the following network functions - one address as the network base address; one address for your AT&T Gateway; and one 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

When you connect to the AT&T network you will get a Dynamic Wide Area Network (WAN) address. The Dynamic WAN address is then associated with your Static IP and acts as a gateway for the Static IP addresses to reach the network. AT&T doesn't automatically assign Static IP addresses to devices connected to the Dynamic WAN. In order to use your Static IP addresses you will need to configure your gateway by following the steps below (or you may contact us for assistance configuring your gateway).

1. Launch a browser window and navigate to IP address 192.168.1.254.
   
2. Click Home Network.
   
3. Click Subnets & DHCP.
   
4. Enter the system password, if prompted. The device access code (system password) is a 10-digit code found on the label side of RG (the label on the 589 is black with white letters). If the customer has changed their password, gather this information from the customer and enter it.
   
5. Under Public Subnet, toggle the Public Subnet Enable from Off to On.
   
6. In the Public IPv4 address field, enter the router address of the public static block. This is the second from last IP address in the IP block.
   
7. In the Subnet Mask field, enter the subnet mask.
   
8. Enter in the first and last usable IP address in the DHCPv4 start address field and the DHCPv4 end address field appropriately.
   
9. In the primary DHCP pool section, click Private radio button if you would like to statically assign your public IPs to your devices, or click Public radio button if you would like the gateway to automatically assign your public IP's by DHCP. Please note if the public option is selected, the gateway will assign your public IP's on a first come first serve basis to any device that makes a DHCP request, including computers, tablets, smartphones, etc. The Private option is recommended.
   
10. Click Save.
    

The gateway is now configured and you can now statically assign the public IP addresses in your devices. If you need assistance with configuring your 3rd party devices to use a static IP, please contact the manufacturer of the device for a further assistance.

Note: Any device using a public IP on a Motorola gateway will not have firewall protection.
