Whitelist AT&T IP addresses

Hello,

I have a few employees at my company who need to be able to access their email on their AT&T smartphones. I will need to whitelist the IP address block(s) of AT&T before they can access the email server however. Can anyone provide the IP address block?

 

Thanks in advance.

Hi @Toasterman 

 

I am not aware of what our IP blocks. I would send a PM to ATTCustomerCare.

 

Keep in mind though that although you need to Whitelist the AT&T IP's, if your employees connect to WiFi anywhere, you will need to also Whitelist those IP addesses as well as that will become the overall IP address the device connects to. Many Home ISP's don't assign static IP's (Including AT&T) that may block access. 

 

Hope this helps!
